Atypical gynecomastia mimicking breast malignancy on mammography,sonography, and 18F‐fluciclovine PET/CT in the setting of biochemical recurrence of prostate cancer

A 60‐year‐old man with metastatic prostate cancer presented with breast swelling for one year. Suspicious breast masses were identified in both breasts with mammography and ultrasound. Biopsy of both masses showed florid gynecomastia without malignancy. Sixteen months later, the patient underwent 18F‐fluciclovine PET/CT for biochemical recurrence of prostate cancer; this showed focal radiotracer uptake in both breasts. Repeat mammogram and ultrasound showed these areas to correspond with the previously biopsied masses, which were stable. To our knowledge, this is the first reported case of gynecomastia mimicking malignancy on 18F‐fluciclovine PET/CT.     

Digital Breast Tomosynthesis: A New Diagnostic Method for Mass‐Like Lesions in Dense Breasts

To compare the rates and accuracy of digital breast tomosynthesis (DBT) and 2D digital mammography (DM) for detecting and diagnosing mass‐like lesions in dense breasts. Mediolateral and craniocaudal images taken with DBT (affected breast) and DM (both breasts) of the dense breasts of 631 women were assessed independently using Breast Imaging Reporting and Data System (BI‐RADS) scores. Images were compared for detection and diagnostic accuracy for masses; sensitivity and specificity of diagnosis; false‐negative and recall rates; and clarity of display, particularly of margins and spicules. Histopathology was conducted via surgical biopsies of all patients. The detection and diagnostic accuracy rates of DBT images (84.3% and 82.3%, respectively) were significantly higher than that of DM (77.3% and 73.4%; p < 0.01, both). The sensitivity and specificity of DBT (68.1% and 95.2%) were higher than that of DM (58.8% and 86.7%), whereas the recall rate of DBT was lower (3.6% cf. 9.8%). The number of cases of benign circumscribed masses and malignant spiculated masses detected by DBT (172 and 182) was significantly higher than the number detected through DM (75 and 115; p < 0.01, both). Radiologists assigned higher BI‐RADS scores for probability of malignancy to DBT images than DM, to lesions proved malignant (p = 0.025); for benign cases, the methods were comparable (p = 0.065). Compared with DM, DBT yielded significantly higher rates of detection and diagnostic accuracy for benign and malignant masses, with greater sensitivity and specificity and lower recall rates. In addition, DBT images facilitated analysis of margins, and the rate of accuracy for judgments of malignancy probability was higher, as proved on biopsy.     

Bilateral breast metastases from prostatic carcinoma: a case report]

We report a case of bilateral breast metastases from prostatic carcinoma. A 49-year-old man with stage D2 prostate cancer, who had been treated by chemoendocrine therapy and radiotherapy for 2 years, complained of bilateral enlarged breasts. Oral administration of diethylstilbestrol diphosphate was started 2 months before the onset of this symptom. A firm mass that was not tender was palpable beneath the skin without fixation on each side. A needle biopsy of the masses showed poorly differentiated adenocarcinoma with positive immunohistopathological staining for prostate-specific antigen. The masses were diagnosed as metastatic adenocarcinoma of prostate gland origin. The patient died 3 months after the diagnosis of breast metastases. Autopsy revealed diffuse lymphogenous metastatic disease. Metastatic prostatic carcinoma to the breast is uncommon. Breast metastases in this patient might be associated with diffuse lymphogenous metastases as well as increased local blood and lymphatic supply caused by extrinsic estrogens.     

Non–Germ Cell Malignancy in Residual or Recurrent Mass After Chemotherapy for Nonseminomatous Testicular Germ Cell Tumor

Background:After chemotherapy for nonseminomatous testicular germ cell tumor (NSTGCT), residual masses or recurrent disease may contain a non–germ cell malignancy (NGCM).Methods:Over 20 years, 369 patients with disseminated NSTGCT were treated with cisplatin-based polychemotherapy at the University Medical Center Groningen. Residual tumor masses were resected in 244 patients and recurrent tumor masses in 37 patients. Histology was reviewed, focusing on the presence of NGCM.Results:Nine patients developed an NGCM. Four patients had an NGCM in the resected residual tumor mass after chemotherapy: three patients had a sarcoma, and one patient had both a sarcoma and an adenocarcinoma. Five patients developed a late recurrence with an NGCM after 39, 40, 72, 72, and 84 months. One patient had a primitive neuroectodermal tumor, one had a sarcoma, and three had an adenocarcinoma in the resected recurrent tumor mass. A complete surgical resection was achieved in five (56%) of the nine patients. After a median follow-up of 48 months (range, 3–271 months), five patients had no evidence of disease (56%), three patients were dead of disease (33%), and one patient was alive with disease (11%).Conclusions:Sarcoma, adenocarcinoma, or both in residual or recurrent tumor masses after combined-modality NSTGCT treatment are rare. Complete surgical resection of the tumor mass is the only curative treatment option.

Tc-99m Sestamibi Scintimammography for the Evaluation of Breast Masses in Patients with Radiographically Dense Breasts

Abstract: The objective of this study was to evaluate the usefulness of technetium-99m sestamibi (MIBI) scintimammography for the diagnosis of breast cancer in patients with palpable breast masses that cannot be adequately evaluated by mammography due to the presence of radiographically dense breasts. At 5 minutes after intravenous injection of MIBI, scintimammograms were obtained in 80 patients who had grade 3 or 4 glandular density on mammograms and a palpable breast mass. Excisional biopsy or FNA biopsy was obtained in 68 lesions in 67 patients. Scintimammography (22 true positive, 4 false positive, 41 true negative, 1 false negative) resulted in a sensitivity of 95.6%, specificity 91.1%, positive predictive value 84.6%, and negative predictive value 97.6%. Mammography (19 true positive, 21 false positive, 24 true negative, 4 false negative) resulted in a sensitivity of 73.9%, specificity 53.3%, positive predictive value 44.7%, and negative predictive value 80%. MIBI scintimammography has a higher sensitivity and specificity than mammography in patients with radiographically dense breasts. It is useful as an adjunct to mammography in those patients with radiographically dense breasts for the characterization of palpable masses. Although sensitivity of mammography in this cohort was high, its specificity was significantly lower than scintimammography. If validated in prospective studies it could provide a safe way of avoiding a breast biopsy in patients with benign findings on clinical exam, mammography, and needle aspiration cytology.     

Mucinous Adenocarcinoma Arising From a Suprapubic Cystostomy Site Without Bladder Involvement

Abstract

Carcinoma arising from a suprapubic cystostomy site in patients with spinal cord injury has been infrequently described. In all previously reported cases, they have been squamous cell carcinomas. Our patient is a 68 year old male with T10 complete thoracic paraplegia who presented with an exophytic mass extending from his suprapubic cystostomy tract. Biopsy revealed mucinous adenocarcinoma. Carcinoma of the suprapubic cystostomy tract should be considered in those patients who present with bloody drainage and/or masses arising from the suprapubic cystostomy site.

Assessing the Relationship of Mammographic Breast Density and Proliferative Breast Disease

Increased breast density and a history of benign breast biopsy are both considered risk factors for developing breast cancer. Understanding the specifics of these risk factors and their relationship to each other can lead to a better understanding of a patient's propensity for breast cancer development and improved surveillance strategies. We included 245 women who underwent a benign breast biopsy without atypia between October 2011 and June 2013. Biopsies were performed for suspicious calcifications as well as masses and architectural distortion. Lesions biopsied were divided into two groups: calcified and noncalcified lesions. The patient's breast density was assessed on most recent mammogram and was classified using the American College of Radiology BI‐RADS density categories. Based on histologic diagnosis, each case was classified as proliferative or nonproliferative breast disease. The median age of the cohort (n = 245) was 55 years (range, 40–84 years). There were 162 (66%) postmenopausal women in the study. A core biopsy was performed for calcifications in 33.5% cases and for noncalcified lesions in 58% cases. In patients with dense breast tissue, an underlying proliferative histology was found significantly more frequently with calcifications (66.7%) as opposed to noncalcified lesions (35.9%) (RR = 2.3 (1.3–4.0); χ² = 8.7; p = 0.003). In nondense breast patients, there was no significant difference (RR = 1.1 (0.7–1.8); χ² = 0.1; p = 0.738). In the postmenopausal group, women with dense breasts had proliferative histology significantly more frequently than women with nondense breasts (55.3% versus 38.3%; p < 0.05), regardless of the underlying lesion type. Postmenopausal women with dense breasts who underwent a breast biopsy with benign histology had a significantly higher likelihood of having proliferative breast disease, regardless of underlying lesion type. Women with dense breasts also showed proliferative histology significantly more often for calcifications as opposed to noncalcified lesions.     

Disseminated high-grade malignant lymphoma involving both breasts

Primary or secondary involvement of the breast is a rare form of extranodal lymphoma. In this paper, we present a 36-year-old female patient admitted to the hospital with bilateral breast masses. Histological examination confirmed high-grade malignant lymphoma involving both breasts.     

Appendiceal carcinoma presenting as a rapidly enlarging abdominal mass

IntroductionAppendiceal adenocarcinomas, although rare, usually present as slow-growing masses. Rarely, do they rapidly enlarge into large abdominal masses over a short period of time. Generally, we attribute rapidly growing abdominal masses to sarcomas, desmoid tumors, or gynecological masses. We present a case of a rapidly growing appendiceal adenocarcinoma in an elderly patient.Case presentationWe report a case of an 83-year-old-male who presented with a one-month history of abdominal pain. A computer tomography (CT) scan identified a lower pelvic mass measuring 7.39 cm × 5.40 cm. A biopsy was done which revealed appendiceal carcinoma. A plan for radiotherapy to reduce the tumor size was made and the patient was discharged. However, the patient returned after three weeks due to worsening abdominal pain and a CT scan identified a significant enhancement in the tumor size. The patient underwent debulking surgery. Pathology of the specimen identified adenocarcinoma of the appendix.DiscussionA rapidly growing carcinoma of the appendix is rare as they are known to have a slow growth rate. A swift diagnosis and intervention are required as these rapidly enhancing neoplasms in the abdomen can become unresectable and metastasize. Although there are various methods of treatment for appendiceal carcinomas, the rapid growth rate and lack of response to radiation required debulking surgery.ConclusionThere exist a myriad of differential diagnoses for a rapidly growing mass in the abdomen. We are presenting the first documented case of a rapidly growing appendiceal adenocarcinoma. Surgeons should be aware of the variety of differentials in such cases.     

Impact of F18-fluorodeoxyglycose positron emission tomography/computed tomography on the management of resectable pancreatic tumours

Background: Positron emission tomography/computed tomography (PET/CT) using F18‐fluorodeoxyglucose has been shown to be valuable in the management of malignant disease. The aim of this study is to investigate the impact of this technique on the management of patients with resectable pancreatic tumours. Methods: Thirty‐six patients with 37 potentially resectable pancreatic tumours on diagnostic CT imaging underwent PET/CT scans. Operative findings, histological reports and/or clinical follow‐up served as standard of reference. The impact of PET/CT on patient management was estimated by calculating the percentage of patients whose treatment plan was altered due to PET/CT. Results: Pancreatic adenocarcinoma was diagnosed in 30 patients, neuroendocrine tumours in 3, mass‐forming pancreatitis in 3 and serous cystadenoma in 1. The median standard uptake (max) value was 5.0 (range 2.2–12.0). Sensitivity and specificity of detecting extrapancreatic metastatic disease were 73% and 100%, respectively. Three occult liver metastases were detected at laparotomy following negative PET/CT. PET/CT findings influenced the management of 8 (22%) patients – 3 with liver metastases, 3 with bone metastases, 1 with lymph node metastases and 1 by identifying the benign appearance of the pancreatic tumour. Conclusion: PET/CT achieves a significant diagnostic impact in detecting extrapancreatic metastatic disease. F18‐fluorodeoxyglucose PET/CT appears to be useful in assessing suspicious pancreatic masses.

Bilateral adrenal gland metastasis of renal adenocarcinoma--a case report

A 72-year-old male patient, who suffered from a renal adenocarcinoma with bilateral adrenal gland metastasis, is reported herein. The patient consulted the urology clinic with complaints of fever and dysuria. On drip infusion pyelography, a mass lesion was discovered in the upper pole of the left kidney. Computerized tomography (CT) revealed the presence of bilateral adrenal masses. On the basis of aortography and CT studies, the patient was diagnosed as having renal cancer with metastasis in bilateral adrenal glands. No other metastasis could be found. Radical left nephrectomy and bilateral adrenectomy were performed. Thereafter, interferon alpha of 3 million units every day was administered intramuscularly for the first 2 months and then, the same dose was given once a week to the present. Supplementary corticosteroids were also administered. His course was uneventful for 18 months after the operation, with no evidence of recurrence.     

Synchronous mucinous adenocarcinoma of the recto sigmoid revealed by and seeding an anal fistula. (A case report and review of the literature)

IntroductionThere are few cases of synchronous rectal adenocarcinoma revealed by an anal fistula. The diagnosis of synchronous mucinous adenocarcinoma of the recto sigmoid and anal canal remains difficult. The chronic anal fistula can be mistaken as the common manifestation of a benign perianal abscess or fistula.Case presentationWe present a rare case of a Greek Caucasian 79 year old male patient with anal fistula and a recurrent perianal abscess who subsequently was found to have developed synchronous rectosigmoid and perianal mucinous adenocarcinoma on biopsy. The histological exam revealed mucinous adenocarcinoma in two sites, representing two tumors, cells were immunopositive for cytokeratin 20 and negative in cytokeratin 7. The patient underwent “laparoscopic extralevator abdominoperineal excision ” with both lesions being resected. There is no recurrence after four years of follow up.ConclusionsThis case highlights the importance of high suspicion, further investigation and the need of biopsy in all anal fistulae.     

Infrared Imaging Does Not Predict the Presence of Malignancy in Patients with Suspicious Radiologic Breast Abnormalities

The NoTouch BreastScan (NTBS) is a non‐invasive infrared imaging device which measures thermal gradients in breasts using dual infrared cameras and computer analysis. We evaluated NTBS as a predictor of breast cancer in patients undergoing minimally invasive biopsy. In this IRB‐approved prospective trial, 121 female patients underwent NTBS prior to scheduled tissue biopsy. Twenty‐two patients were excluded due to uninterpretable scans (n = 18), diagnosis of a nonprimary breast malignancy (n = 1), or no biopsy performed (n = 3) for a total of 99 patients. Five patients had bilateral breast biopsies and one patient had two ipsilateral biopsies, resulting in 105 biopsies. Patients were prospectively scanned using a high specificity mode, termed NTBS1. All 99 patients were retrospectively re‐evaluated in a high sensitivity mode, NTBS2. Of 105 biopsies performed in 99 women, 33 (31.4%) were malignant and 72 (68.6%) were benign. NTBS1 demonstrated a sensitivity of 45.5% and a specificity of 88.9%. Of 94 normal contralateral breasts, 9.6% had a positive NTBS1. In the retrospective evaluation, NTBS2 demonstrated a sensitivity of 78.8% and a specificity of 48.6%. Half (50%) of the normal contralateral breasts had a positive NTBS2. NTBS does not accurately predict malignancy in women with suspicious imaging abnormalities. The higher sensitivity mode results in an unacceptable number of false positives, precluding its use. Infrared imaging did not improve the sensitivity or specificity of mammography in this clinical setting.     

Etiology of Breast Masses after Autologous Breast Reconstruction

Background

Determining the nature of a breast mass after autologous reconstruction can be difficult.

Methods

A retrospective review of all autologous breast reconstructions was performed over 10 years. All postoperative breast masses were identified. Tumor characteristics, adjuvant treatment, timing of the development of the mass, and correlation with radiology were reviewed.

Results

A total of 365 flaps were performed on 272 patients [253 deep inferior epigastric perforator (DIEP), 35 superficial inferior epigastric artery (SIEA), 22 muscle-sparing free transverse rectus abdominis myocutaneous (free MS-TRAM), 25 latissimus, and 30 pedicled TRAM]. Breast masses were identified in 66 breasts (18 %). The majority of these were from fat necrosis, occurring in 54 breasts (15 % overall; DIEP 13.4 %, SIEA 5.7 %, free MS-TRAM 15 %, latissimus 0 %, pedicled TRAM 47 %), first identified at a mean of 3 months. Recurrent carcinoma was diagnosed in 13 breasts (3.6 %). Factors associated with the postreconstruction mass representing recurrent carcinoma were later time period after reconstruction (mean 24 months), closer surgical margins, and lymphovascular invasion. Radiographic imaging accurately diagnosed recurrent carcinoma in 11 (92 %) of 12 patients in whom it was utilized and suggested a benign diagnosis in all 16 patients with fat necrosis in whom it was utilized.

Conclusions

Breast masses frequently present after autologous reconstruction. Fat necrosis is the most common cause. Recurrent carcinoma can occur in the reconstructed breast and presents later. A higher index of suspicion for recurrence should accompany any mass in which prior lymphovascular invasion was present or if original margins were <1 cm. Radiographic imaging accurately identifies the cause of these masses.     

Imaging Characteristics of Male Breast Disease

Abstract: The purpose of the study was to describe the imaging findings of male breast disease. One hundred and sixty‐four male patients, who underwent mammography and ultrasonography (US) between January 1999 and December 2008, were retrospectively evaluated. Seventy‐five patients (46%) underwent biopsy, and 89 patients (54%) were diagnosed radiologically. The radiologic and pathologic diagnoses in 164 cases of this series were 13 cancers (8%), including one ipsilateral and one contralateral breast cancers, 147 cases of gynecomastia (90%), one fibroadenoma (0.6%), two cases of fibrocystic disease of the breast (1.2%), and one epidermoid inclusion cyst (0.6%). Three mammographic patterns were adequate to describe all 147 cases of gynecomastia in our series: 53 patients (36%) had nodular gynecomastia, 46 patients (31%) had dendritic gynecomastia, and 48 patients (33%) had diffuse gynecomastia. Gynecomastia was unilateral in 65% of cases (n = 95), and bilateral in 35% of cases (n = 52). On physical examination, two of the malignant lesions had no clinic features of malignancy (15%). On mammography, 11 of 13 malignant masses were demonstrated (85%). A mass with microcalcifications was seen on mammograms in one case (9%). The contours of the masses were irregular in nine cases (82%), well‐circumscribed in two cases (18%). The location of the masses was retroareolar in seven cases (64%) and eccentric to the nipple in four cases (36%). The size of the masses varied between 0.5 cm and 5 cm (mean 2.4 cm). Nipple retraction was evident in five cases (45%), and skin thickening in four cases (36%). All of the malignant masses were demonstrated on ultrasound; however, one of them was seen retrospectively after mammography. All of the masses were hypoechoic and solid, the contours were well‐defined and smooth in two masses (15%), and irregular in 11 masses (85%), and five masses (39%) had posterior prominent shadowing. Axillary lymphadenopathia was detected in two cases (15%). One patient had a previous contralateral breast cancer, and one had an ipsilateral. On mammography, breast cancer characteristically exhibits an irregular subareolar mass, nipple retraction, and skin ulceration or thickening, but sometimes breast cancer has a well‐circumscribed contour and punctuated microcalcifications. Ultrasonography is essential and useful for further characterization and helpful for demonstrating lymphadenopathies of the axillary region.     

Establishing prostate cancer patient derived xenografts: Lessons learned from older studies

Background

Understanding the progression of prostate cancer to androgen‐independence/castrate resistance and development of preclinical testing models are important for developing new prostate cancer therapies. This report describes studies performed 30 years ago, which demonstrate utility and shortfalls of xenografting to preclinical modeling.

Methods

We subcutaneously implanted male nude mice with small prostate cancer fragments from transurethral resection of the prostate (TURP) from 29 patients. Successful xenografts were passaged into new host mice. They were characterized using histology, immunohistochemistry for marker expression, flow cytometry for ploidy status, and in some cases by electron microscopy and response to testosterone. Two xenografts were karyotyped by G‐banding.

Results

Tissues from 3/29 donors (10%) gave rise to xenografts that were successfully serially passaged in vivo. Two, (UCRU‐PR‐1, which subsequently was replaced by a mouse fibrosarcoma, and UCRU‐PR‐2, which combined epithelial and neuroendocrine features) have been described. UCRU‐PR‐4 line was a poorly differentiated prostatic adenocarcinoma derived from a patient who had undergone estrogen therapy and bilateral castration after his cancer relapsed. Histologically, this comprised diffusely infiltrating small acinar cell carcinoma with more solid aggregates of poorly differentiated adenocarcinoma. The xenografted line showed histology consistent with a poorly differentiated adenocarcinoma and stained positively for prostatic acid phosphatase (PAcP), epithelial membrane antigen (EMA) and the cytokeratin cocktail, CAM5.2, with weak staining for prostate specific antigen (PSA). The line failed to grow in female nude mice. Castration of three male nude mice after xenograft establishment resulted in cessation of growth in one, growth regression in another and transient growth in another, suggesting that some cells had retained androgen sensitivity. The karyotype (from passage 1) was 43–46, XY, dic(1;12)(p11;p11), der(3)t(3:?5)(q13;q13), ‐5, inv(7)(p15q35) x2, +add(7)(p13), add(8)(p22), add(11)(p14), add(13)(p11), add(20)(p12), ‐22, +r4[cp8].

Conclusions

Xenografts provide a clinically relevant model of prostate cancer, although establishing serially transplantable prostate cancer patient derived xenografts is challenging and requires rigorous characterization and high quality starting material. Xenografting from advanced prostate cancer is more likely to succeed, as xenografting from well differentiated, localized disease has not been achieved in our experience. Strong translational correlations can be demonstrated between the clinical disease state and the xenograft model. Prostate 75: 628–636, 2015. © The Authors.

The Lateral Inframammary Fold Incision for Nipple‐Sparing Mastectomy: Outcomes from Over 50 Immediate Implant‐Based Breast Reconstructions

Nipple‐sparing mastectomy (NSM) as a therapeutic or prophylactic procedure for breast cancer is rapidly gaining popularity as the literature continues to support it safety. The lateral inframammary fold (IMF) approach provides adequate exposure and eliminates visible scars on the anterior surface of the breast, making this incision cosmetically superior to radial or periareolar approaches. We reviewed 55 consecutive NSMs performed through a lateral IMF incision with immediate implant‐based reconstruction, with or without tissue expansion, between June 2008 and June 2011. Prior to incision, breasts were lightly infiltrated with dilute anesthetic solution with epinephrine. Sharp dissection, rather than electrocautery, was used as much as possible to minimize thermal injury to the mastectomy flap. When indicated, acellular dermal matrix was placed as an inferolateral sling. Subsequent fat grafting to correct contour deformities was performed in select patients. Three‐dimensional (3D) photographs assessed changes in volume, antero‐posterior projection, and ptosis. Mean patient age was 46 years, and mean follow‐up time was 12 months. Twelve mastectomies (22%) were therapeutic, and the remaining 43 (78%) were prophylactic. Seven of the nine sentinel lymph node biopsies (including one axillary dissection) (78%) were performed through the lateral IMF incision without the need for a counter‐incision. Acellular dermal matrix was used in 34 (62%) breasts. Average permanent implant volume was 416 cc (range 176–750 cc), and average fat grafting volume was 86 cc (range 10–177 cc). In one patient a positive intraoperative subareolar biopsy necessitated resection of the nipple‐areola complex (NAC), and in two other patients NAC resection was performed at a subsequent procedure based on the final pathology report. Mastectomy flap necrosis, requiring operative debridement, occurred in two breasts (4%), both in the same patient. One of these breasts required a salvage latissimus dorsi myocutaneous flap to complete the reconstruction. Three nipples (6%) required office debridement for partial necrosis and operative reconstruction later. No patient had complete nipple necrosis. No statistically significant differences existed between therapeutic and prophylactic mastectomies for developing partial skin and/or nipple necrosis (p = 0.35). Three episodes (5%) of cellulitis occurred, which responded to antibiotics without the need for explantation. Morphological outcomes using 3D scan measurements showed reconstructed breasts were larger, more projected, and less ptotic than the preoperative breasts (196 versus 248 cc, 80 versus 90 mm, 146 versus 134 mm, p < 0.01 for each parameter). Excellent results can be achieved with immediate implant‐based reconstruction of NSM through a lateral IMF incision. NAC survival is reliable, and complication rates are low. blechmanplasticsurgery.com     

Primary Pulmonary Adenocarcinoma Metastatic to the Uvea,Brain and Adrenal Gland in a Dog

A 10‐year‐old male Briard dog was presented because of listlessness, abnormal gait, fever, inappetence, and seizures. A non‐pigmented growth was observed in the ventral quadrant of the left iris. Thoracic radiographs revealed multiple pulmonary metastases and the owner opted for killing. On necropsy, lung masses and nodules in left iris, right adrenal medulla, and brain were detected. Histologically the primary tumour was diagnosed as pulmonary adenocarcinoma with predominant solid pattern. Metastases to regional lymph nodes, uvea, adrenal medulla, and brain were recognized. The metastatic behaviour resembled that occurring in humans. To the authors’ knowledge, this is the first report of a pulmonary adenocarcinoma with metastasis to the uvea in a dog.
