An autopsy case of triple cancers including signet-ring cell carcinoma of the breast —Report of a rare case with reference to a review of the literature—

A 67 year old Japanese woman who had been suffering from general fatigue was diagnosed as having metastasis of signet-ring cell carcinoma of the bone marrow from a biopsied specimen. A clinical effortive search to the systemic organs revealed a tumor of 4×3 cm in size in the lower part of her left breast, which was subsequently diagnosed as the primary site histopathologically. The patient was immediately treated surgically, however, her general condition generally deteriorated and she expired 5 months after the operation. Autopsy revealed dissemination of tumor cells in the bone marrow, bilateral pleura, and soft tissue around the operated site. The autopsy additionally revealed squamous cell carcinoma of keratinizing type in the uterine cervix and well differentiated tubular adenocarcinoma in the gallbladder. A review of the literature revealed this case to be the first reported case of triple cancers including signet ring-cell carcinoma of the breast, proven by autopsy in Japan.     

Spindle Cell Metaplastic Breast Carcinoma with Leiomyoid Differentiation: A Case Report

BACKGROUND: Metaplastic carcinoma of the breast is a rare but distinct entity within the group of undifferentiated invasive carcinomas. This entity accounts for less than 0.5% of all breast cancers and contains elements of epithelial (ductal), mesenchymal, and intermediate forms of differentiation. Of these metaplastic carcinomas, there have been reports of chondroid, squamous, osseous, and spindle differentiation. CASE REPORT: We describe the clinical course of a 52-year-old female patient with an unusual histopathology of a spindle cell carcinoma of the breast, discuss the literature, and recommend an approach to diagnosis and treatment. The patient initially presented to an outside hospital with a rapidly growing breast mass that was originally diagnosed as a malignant phylloides tumor. She presented 11 months after the primary treatment with a local subcutaneous relapse. She later developed a local relapse of her metaplastic carcinoma in the chest wall. Extensive histopathological analysis lead to the diagnosis of a spindle cell metaplastic breast carcinoma with leiomyoid differentiation, which has not been described previously. CONCLUSIONS: Overlap in morphology can lead to a misinterpretation or underdiagnosis of metaplastic carcinomas. However, the prognosis is similar to more common types of breast adenocarcinoma.     

Pure and primary squamous cell carcinoma of the breast

A case of a pure squamous cell carcinoma (SCC) of the breast is a 75 y.o. white female is reported. The cancer was discovered at the clinical exam requested by the patient for a growing mass in the left breast. Mammogram and an ultrasound exam showed a big cystic mass (4 cm x 4 cm) with a liquid content and a small polypoid mass of 0.5 cm x 0.5 cm arising from the inner surface of the cyst. A fine needle aspiration was done and the cytological report was consistent with squamous cell carcinoma. A left modified radical mastectomy was carried out. The skin was not involved and the lymph nodes were negative, and no other cutaneous tumor elsewhere was found. The stage was II (T 2a N o M o). The patient did well and was discharged 10 days post-op and now she is still doing well with no signs of recurrences or metastasis. This cancer should not be confused with a much more largely manifest metaplastic changes in a usual breast cancers. The criteria to define "pure" a squamous cell Ca of the breast are: 1) that no other neoplastic element such as ductal or mesenchymal ones are present in the tumor; 2) that the tumor is independent of adjacent cutaneous structure; 3) that no other distant epidermoid tumor exists in the patient. The origin of this tumor is controversial; it has been stated as arising from dermatoid cyst of the breast, chronic abscesses, complete metaplasia of glandular breast tissue. Despite the rarity of this neoplasia it should be kept in mind that in a cystic mass of the breast in older patient could arise a squamous cell carcinoma.     

Unusual collision tumor with infiltrating ductal carcinoma and breast skin squamous cell carcinoma: A case report and literature review

IntroductionBreast cancer is the most common diagnosed cancer among women worldwide. Invasive ductal carcinoma (IDC) is the most common type, on the other hand, squamous cell carcinoma of the skin (SCC) overlying the breast is a rare tumor. The co-presence of two tumor types in one organ is even a rarer entity, termed as collision tumor. Only 3 known cases of collision tumor with breast invasive ductal and skin squamous carcinoma were reported in the literature.Case presentationAn otherwise medically free 91-year-old, postmenopausal, female presented with left breast fungating mass for four months. Pre-operative core tissue biopsy and incisional skin biopsy revealed two distinct tumor subtypes of invasive ductal carcinoma, positive for progesterone, estrogen receptors and negative for human epidermal growth factor receptor 2, as well as skin squamous cell carcinoma, and axillary lymph node metastasis. Patient underwent left breast modified radical mastectomy and split skin grafting for wound closure. The final histopathology was consistent with grade 2 IDC. The nipple and areola complex were involved by moderately differentiated squamous cell carcinoma. Currently patient on adjuvant hormonal treatment. Follow up showed no local recurrence or distal metastasis.ConclusionCollision tumors of the breast with IDC and SCC of the overlying skin is very rare. The surgeon has to be aware of of such entity as the proper peri-operative management should be tailored to target the most aggressive histologic subtype.     

Thymic carcinoma (mixed small cell undifferentiated squamous cell carcinoma); report of a case

A 52-year-old man was admitted to our hospital on October, 1997 with complains of left anterior chest pain. A chest X-ray and computed tomography on admission showed evidence of a mass in the left anterior mediastinum. The patient was treated with combination chemotherapy [cisplatin (CDDP), etoposide (VP-16)] and radiation therapy (2 gray x 25 days), preoperatively. Median sternotomy revealed a tumor invading into the left anterior chest wall, the pericardium, and partial pleura. The tumor was extirpated with combined resection of invaded organs. Microscopically and immunohistochemically, the tumor was diagnosed mixed small cell and undifferentiated squamous cell carcinoma documented by Snover et al. The patient was discharge on March 1998, but 2 years later after operation, he was dead by recurrent. We reported a rare case of thymic carcinoma.     

The Development of New, Primary, Noninvasive Carcinoma of the Breast 29 Years after Bilateral Radical Mastectomy

Abstract: We present the case of a patient with a new, primary noninvasive breast carcinoma arising in residual breast tissue 29 years after radical mastectomy. The patient, a 75-year-old black woman with no family history of breast or ovarian cancer, had undergone left radical mastectomy in 1956 (age 35) and right radical mastectomy in 1965 (age 44). Examination revealed a 3-mm nodule in the right anterior axillary line. On excision, the lesion was a 1.5-mm intracystic papillary ductal carcinoma in situ arising in a background of atypical ductal hyperplasia (representing residual breast tissue). The patient has not agreed to testing for BRCA1 or BRCA2 mutations. The theoretical risk of new primary breast cancers arising in residual breast tissue has been suggested as a reason why prophylactic mastectomy may not be completely effective. This case suggests that even after what appeared to be aggressive radical mastectomy, enough breast tissue remained so that the patient was at risk for recurrent breast cancer.

Mohs Micrographic Surgery for Squamoid Eccrine Ductal Carcinoma

Background. Squamoid eccrine ductal carcinoma is a rare cutaneous malignancy. There are no accepted standards for surgical margins in eccrine carcinomas.
Objective. We report a case of squamoid eccrine ductal carcinoma resembling squamous cell carcinoma and discuss Mohs micrographic surgery as a surgical modality for eccrine carcinomas.
Method. The patient was a 30-year-old Korean woman with a 4-year history of a nodule on her neck. Following primary diagnosis of squamous cell carcinoma by punch biopsy, the tumor was completely removed by Mohs micrographic surgery with a 2 mm cancer-free margin.
Result. A one-stage Mohs micrographic surgical procedure was performed, and the size of the tumor mass was 2.3 × 2.5 cm in width and 1.5 cm in depth. On histopathologic examination, the tumor was characterized by both eccrine and squamous differentiation. The squamous cells expressed epithelial membrane antigen and cytokeratin 5 and 6, and the cells forming ductal structures expressed anti–carcinoembryonic antigen. Although eccrine carcinomas show a generally aggressive clinical course, the patient was disease free at 14 months after surgery.
Discussion. Squamoid eccrine ductal carcinoma should be considered in the differential diagnosis of squamous cell carcinoma and other cutaneous adnexal neoplasms showing squamoid and ductal features of differentiation. In addition, Mohs micrographic surgery can be an option sufficient for complete surgical removal of eccrine carcinomas such as squamoid eccrine ductal carcinoma.

Radiation-induced squamous cell carcinoma of the chest wall seven years after adjuvant radiotherapy following the surgery of breast cancer: a case report

A 54-year-old woman, who had underwent an adjuvant radiotherapy following the modified radical mastectomy in the left primary breast cancer in June 1988. She underwent second surgery and adjuvant radiotherapy (electronic radiotherapy) for recurrent breast cancer in the major pectoral muscle and received chemoimmunotherapy in May 1989. In May 1996 she complained of two ulcers of the chest wall. The ulcer biopsy findings was squamous cell carcinoma, and we diagnosed she fell the radiation-induced skin cancer. She underwent chest wall resection and reconstruction with vertical rectal abdominal musculocutaneous flap (VRAM). However two months later her chest wall resection, she again got the recurrent squamous cell carcinoma in the right axillary lymph nodes and left pleura. The third radiotherapy and the chemotherapy with pepleomycin were uneffective on her recurrent cancer. And she died in March 1997.     

Synchronous Bilateral Breast Cancer with Paget's Disease and Invasive Ductal Carcinoma: Report of a Case

We report a case of synchronous bilateral breast cancer with Paget's disease and invasive ductal carcinoma. A 60-year-old Japanese woman presented with an 8-month history of discharge from the left nipple with eczema and itching. Mammography showed grouped fine calcification in the right breast, which was highly suggestive of right breast carcinoma with an intraductal component. Ultrasonography did not reveal any mass lesions in the bilateral breasts, and computed tomography and bone scintigraphy showed no site of distant metastasis. We performed a modified radical mastectomy for Paget's disease in the left breast and breast-conserving surgery for ductal carcinoma in the right breast. The histological diagnosis was Paget's disease in the left breast and invasive ductal carcinoma with a predominant intraductal component in the right breast. There was no metastasis in any of the 24 left axillary lymph nodes resected. We also gave her postoperative adjuvant chemoendocrine therapy, comprised of tamoxifen (20mg) and UFT (uracil/tegafur) (400mg) daily. The patient has been disease-free for 4 years since her operation.     

Successful treatment of triple primary tumor

INTRODUCTIONThe occurrence of multiple primary tumors is rare. Only limited number of cases with triple malignancy have been reported. We report here a rare case of a woman presented synchronous triple tumors, in her lung, breast, skin.PRESENTATION OF CASEA 56-year-old woman presented with invasive ductal carcinoma of breast, non-small cell lung cancer and malignant melanoma. The patient undergone mastectomy and malignant melanoma tumor excision on-site. After operation stereotactic radiotherapy was given to her lung tumor. Six course of chemotherapy was given to her. She is alive with no progression.DISCUSSIONThe patient was diagnosed with melanoma and staging by FDG/PET. There is not any study about routine using PET/CT in the melanoma staging.CONCLUSIONThis is a very rare synchronous triple tumor case.     

Primary squamous cell carcinoma of the breast in a pregnant woman: Report of a case

Although reports on primary squamous cell carcinoma of the breast have been increasing in number, the morbidity rate of the disease is comparatively low. Its onset in pregnant women, especially, is quite rare. We herein report a case of primary squamous cell carcinoma of the breast in a pregnant woman. A 33-year-old woman was admitted with a lump in the right breast and an abnormal bloody nipple discharge. The breast mass was 5.6×5.4 cm in size, and both ultrasonogram and CT scanning showed that it consisted of a cystic tumor for the most part. A large amount of bloody cystic fluid was aspirated by fine-needle aspiration; squamous cell carcinoma of the breast was suspected by a cytological study on the fluid. Twelve days after an induced abortion was performed, a modified radical mastectomy was carried out. Histological findings of the resected specimen demonstrated that the tumor was squamous cell carcinoma which had been well differentiated with partial keratinization and cancer pearls. Noninvasive ductal carcinoma was also observed in a very small region of the specimen, which indicated that the tumor was probably originally adenocarcinoma which later transformed into squamous cell carcinoma.     

Invasive Ductal Carcinoma of the Breast Associated with Poland's Syndrome: Report of a Case

We report herein a rare case of invasive ductal carcinoma of the breast associated with Poland's syndrome. The patient was a 59-year-old woman who was referred to our department after a nodule had been found in the upper outer portion of the left breast by a breast cancer screening program. On physical examination, marked hypoplasia of the right breast and upper limb was noted. Preoperative computed tomography also revealed a defect in the right pectoralis muscles. A quadrantectomy of the left breast with lymphadenectomy was subsequently performed and pathological examination of the resected specimen showed invasive ductal carcinoma. Her medical history revealed that her mother had attempted to abort the pregnancy around the fifth week of her gestation. The present case suggests that such an event during gestational development may be associated with congenital anomalies predisposing to malignant disorders.

Breast cancer metastasizing to the contralateral axilla several years after treatment: A case report with literature review

Introduction and importanceLymph node metastasis is the most prominent prognostic factor in breast cancer. The aim of this paper is to report a case of contralateral axillary lymph node metastasis (CAM) which look like metachronous initially, but histopathologicaly confirmed as synchronous CAM.Case presentationA-44-year old female was a known case of left breast cancer five years prior to this presentation (T2,N2,M0, grade III, Triple negative, multifocal invasive ductal carcinoma). On follow up, multiple contralateral axillary suspicious lymph nodes were discovered. Fine Needle Aspiration Cytology from the lesion revealed grade III, Triple negative, invasive ductal carcinoma consistent with metastasis from the left invasive ductal carcinoma. Bilateral mastectomy and right axillary dissection were performed. The histopathological examination and immunohistochemistry showed left breast recurrent 0.5 cm grade III, Triple negative invasive ductal carcinoma.DiscussionIf a cancer is found in the contralateral axilla, three main potential sources should be considered: contralateral spread from the original breast tumor, metastasis from an occult primary in the ipsilateral breast, and metastasis from an extramammary site.ConclusionAlthough CAM in patients with breast cancer is an uncommon condition, it is still possible to occur. There is a controversy regarding the appropriate management.     

Internal mammary artery perforator propeller flap for contralateral mastectomy defect: A case report

The internal mammary artery perforator (IMAP) flap can be used as either loco‐regional or free flap, and provides thin flexible coverage for defects of the chest wall and cervical regions. In this report, we present a bilateral mastectomy case in which the left mastectomy defect was closed with an IMAP propeller flap harvested from the right breast. Our patient with a history of left breast conservation therapy was diagnosed invasive ductal carcinoma in her left breast 14 years later. On physical examination, the patient's left breast displayed the stigmata of radiotherapy including dark discoloration and firmness to palpation, compared to contralateral pendulous breast. After bilateral mastectomy, an IMAP flap with a size of 26 cm × 11 cm was harvested from right chest and was transposed 180 degrees clockwise in a propeller fashion to the left mastectomy defect without any tension. The flap survived without any complication and the patient was free of recurrence or metastases during the follow‐up of 18 months. The patient was satisfied with the outcome. IMAP propeller flap could be harvested safely to the anterior axillary fold in the subcutaneous fat plane. It may provide a large skin paddle especially in large breasted women. © 2016 Wiley Periodicals, Inc. Microsurgery 36:507–510, 2016.     

A case of squamous cell carcinoma of the thymus

A case of squamous cell carcinoma of the thymus was reported. A 60-year-old female was admitted because of swelling of left cervical and left axillary lymph nodes. Chest X-ray revealed left anterior mediastinal mass shadow. The histological examination on the excised left axillary lymph nodes revealed well differentiated squamous cell carcinoma. After radiotherapy, the operation was performed with median sternotomy and then the mediastinal tumor was diagnosed squamous cell carcinoma originated from the thymus. The postoperative course of the patient was unfavorable, though adjacent postoperative radiotherapy and chemotherapy. Compared with ordinary thymoma, squamous cell carcinoma of the thymus commonly metastasizes outside the thorax and has poor prognosis. In view of these differences, it should be separated histologically from ordinary thymoma.     

Metaplastic spindle cell carcinoma of the breast in a patient with neurofibromatosis type 1

We report a unique case of a 67‐year‐old woman with neurofibromatosis type 1, who was also diagnosed with metaplastic spindle cell carcinoma of the left breast. She had many neurofibromatosis lesions on her body, as well as the mass in the left breast. After the breast mass was diagnosed as a malignant mesenchymal tumor by core needle biopsy, the patient underwent left modified radical mastectomy. Subsequently, the pathological analysis of the tumor showed it to be a metaplastic spindle cell carcinoma. The co‐occurrence of neurofibromatosis type 1 and breast cancer, in particular metaplastic spindle cell carcinoma, is very rare.     

Malignant Eccrine Spiradenoma: A Case Report and Review of the Literature

BACKGROUND: Eccrine spiradenoma is a well-differentiated benign tumor of the sweat glands. Malignant change arising within eccrine spiradenoma is rare. OBJECTIVE: We describe a patient with malignant eccrine spiradenoma exhibiting both carcinomatous and sarcomatous differentiation. METHODS: Case report and literature review. RESULTS: A 37-year-old woman noted enlargement of a left axillary tumor that had been present for 20 years. The tumor was resected and the specimen, measuring 3.0 cm x 1.5 cm, revealed an encapsulated benign eccrine spiradenoma as well as an undifferentiated carcinoma possessing both carcinomatous and sarcomatous components. A transition zone was evident between the benign eccrine spiradenoma and the undifferentiated carcinoma, suggesting that the latter had arisen from the benign tumor. The malignant areas consisted principally of undifferentiated carcinoma (70%), although squamous cell carcinoma (10%), adenocarcinoma (10%), and chondrosarcomatous (10%) components were also present. Numerous mitotic figures were noted within the areas of malignant change, suggesting that the tumor was aggressive in nature. The patient died of systemic metastases 7 months after diagnosis. CONCLUSION: Although eccrine spiradenomas are usually benign, they can, on rare occasions, undergo malignant transformation. This case report describes one such occurrence of malignant transformation of a benign eccrine spiradenoma that unfortunately resulted in the patient's death from systemic metastases 7 months after diagnosis.     

Secretory Carcinoma of the Breast with a Cystically Dilated Intraductal Component: Report of a Case

A case of secretory carcinoma of the breast in a 61-year-old woman is described. She came to our hospital complaining of a bloody nipple discharge. The physical examination revealed a 2.8 × 2.1-cm, firm, irregular lump with bloody nipple discharge in her left breast. Mammography demonstrated an irregular mass and ultrasonography showed an irregular hypoechoic mass accompanied with a cyst. Ductgraphy was done. It showed a dilated mammary duct leading to the cyst which was partially occupied with carcinoma. A cytologic smear of the nipple discharge and fine-needle aspiration cytology revealed similar findings, and both findings were malignant. A modified radical mastectomy was performed. A pathological examination revealed secretory carcinoma of the breast which had spread inward and outward from the cyst. In addition, the nipple discharge flowed from the cyst through the dilated mammary duct. The patient is presently alive and well 2 years after the operation. Secretory carcinoma is an extremely rare tumor of the breast and 48 cases have been reported in Japan. The present case is the first known case of secretory carcinoma demonstrating a bloody nipple discharge to come from a cyst which has been invaded by carcinoma.

A case of squamous cell carcinoma of the renal pelvis accompanying an ectopic opening with vesicoureteral reflux of complete duplication of uretero pelvis

Squamous cell carcinoma of the renal pelvis is a relatively rare disease. Recently, we observed a case of squamous cell carcinoma of the renal pelvis with vesicoureteral reflux in a 49-year-old female patient. Her main symptom was abdominal pain on the left side. The complete duplications of uretero-pelvis on both sides, and vesicoureteral reflux in the upper left part of the kidney were recognized by means of various examinations. During the operation, a tumor was found in the upper left renal pelvis, and in the ureter belonging to the upper left renal pelvis. Pathologically, it was diagnosed as a squamous cell carcinoma. After the extraction of the left uretero-pelvis, 50 Gy of radiotherapy was administered to the patient. However, she died four months after the operation.
