A case of quadruple primary malignancies including breast,tongue, and thyroid cancers and osteosarcoma in a young female without karyotype abnormality

The patient was a 41-year-old, premenopausal woman with a chief complaint of well-circumscribed palpable, right breast mass without nipple discharge. Although she noticed the lump 3 months previously, the size of the tumor (1.1 × 0.9 cm²) had been stable. The patient’s mother suffered from gastric cancer. Her previous history of the triple different malignancies was as follows: (1) left osteosarcoma [amputation of left lower leg at 15 years old (y/o)]. After the operation, she was treated with various kinds of anticancer drugs including a total of 45 g ifosphamide and 342 g methotrexate; (2) tongue cancer (right radical neck resection; 23 y/o); and (3) thyroid cancer (right lobectomy; 40 y/o). There was no evidence of recurrence of these malignancies at the present consultation. At the time of tongue cancer operation, chromosome abnormality was investigated, but the results were normal. Physical examination showed a well-delimited, elastic-firm, mobile tumor in the central outer right breast. Regional lymph nodes were not palpable. Mammography showed a focal asymmetry in the right upper breast on the mediolateral oblique view. Ultrasonography revealed a hypoechoic mass with irregular margins. Distant metastases could not be detected by whole-body computed tomography scan. The histology of the Mammotome^® (vacuum-assisted core needle biopsy) specimen revealed that this tumor was low-grade ductal carcinoma in situ (DCIS). She underwent breast-conserving surgery with sentinel lymph node biopsy. On permanent histopathological examination, the diagnosis of the tumor was intracystic papilloma with low-grade DCIS. Surgical margin was negative, and sentinel lymph node metastases could not be observed. Estrogen and progesterone receptor (ER/PR) were strongly positive, but human epidermal growth factor receptor-2 (HER-2) overexpression was not tested because the lesion was DCIS. She has received no adjuvant therapy and is currently disease free 3 months after surgery.     

Synchronous bilateral male breast cancer: a case report

Synchronous bilateral breast cancer is extremely rare in men and has not, up to date, been reported in Korea. A 54-year-old man presented with a palpable mass in the right breast. The right nipple was retracted and bilateral axillary accessory breasts and nipples were present. On physical examination, a 2 cm-sized mass was palpated directly under the right nipple, and, with squeezing, bloody discharge developed in a single duct of the left nipple. There was no palpable mass in the left breast, and axillary lymph nodes were not palpable. Physical examination of external genitalia revealed a unilateral undescended testis on the left side. Synchronous bilateral breast cancer was diagnosed using mammography, ultrasonography, and core-needle biopsy. Histopathological examination revealed invasive ductal carcinoma in the right breast and ductal carcinoma in situ in the left breast. Bilateral total mastectomy, sentinel lymph node biopsy, and excision of accessory breasts in the axilla were performed.     

Non-invasive secretory carcinoma of the breast

A case of non-invasive secretory carcinoma of the breast is reported. The patient was a 33-year-old Japanese woman who complained of abnormal nipple discharge from the right breast. Although physical and radiological examinations failed to find any abnormal nodular lesions in the breast, a cytological examination revealed signet-ring-like atypical cells in the smears of nipple discharge. Radical mastectomy with axillary lymph nodes dissection was performed. No nodular lesions were macroscopically observed. However, intraductal proliferation of atypical cells was microscopically found in the excised breast. Diastase-resistant PAS-positive mucus was observed in the tumor-cell-forming-lumina and in the cytoplasm of tumor cells. No metastases were observed in the axillary lymph nodes.     

A case of occult breast carcinoma with irradiation therapy and axillary lymph node dissection

A 78-year-old woman was seen at the hospital for a swollen left axillary node. There was an elastic hard mass measuring 0.7 cm in diameter in the left axilla, but no breast mass was palpable in the bilateral breasts. Mammography did not reveal any tumor and calcification, and there was no abnormalities on breast ultrasonography (US), computed tomography (CT) and magnetic resonance imaging (MRI). Aspiration biopsy cytology of the left axillary node revealed adenocarcinoma. Systemic examination failed to reveal primary lesion. Thus, to make the diagnosis, we enucleated the axillary nodule. Immunohistochemical staining for the excisional specimen revealed an estrogen receptor, progesterone receptor and gross cystic disease fluid protein-15 (GCDFP-15) was strongly positive, so we diagnosed it as an occult breast carcinoma. After obtaining her informed consent, the patient underwent left axillary lymph node dissection and irradiation therapy of the left breast. The patient has been disease-free under adjuvant chemoendocrine therapy. We treated the occult breast carcinoma with radiation therapy of the breast and axillary lymph node dissection, and provided a review of the literature.     

Breast Carcinoma with Choriocarcinomatous Features: A Case Report

Nongestational choriocarcinoma differentiation is extremely rare in breast neoplasms. It is characterized by tumor cells similar to chorionic trophoblastic cells, which react with human placental lactogen and human chorionic gonadotropin (hCG). A 56-year-old woman presented with a palpable right breast mass without past history of trophoblastic tumors. An F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) scan revealed one focus with low accumulation of FDG in the right breast (maximum standardized uptake value, 1.98). The patient underwent a right mastectomy and biopsy of sentinel nodes. Microscopically, the tumor was a typical invasive ductal carcinoma with multiple foci of choriocarcinoma features. Immunohistochemistry showed that the tumor cells resembling choriocarcinoma were positive for hCG antibody, but negative for HER2/neu, estrogen receptor, and progesterone receptor. A pathologic diagnosis of breast carcinoma with choriocarcinomatous features was made. To our knowledge, this is the first report of invasive carcinoma with choriocarcinomatous features and an unusual finding of low accumulation in an F-18 FDG PET/CT scan in Korea.     

A case of non-palpating breast cancer with huge lymph node metastasis

We report a case of non-palpating breast cancer with huge lymph node metastasis. The patient was a 58-year-old woman who had a huge tumor at her right armpit. The tumor was 4 cm in diameter. Aspiration biopsy cytology for the tumor was performed. The diagnosis is Class V. Mammography showed an ill-defined mass at her right breast. Ultrasonography revealed a low echoic mass at the C area of her right breast. A core needle biopsy for the breast tumor led to a diagnosis of an invasive ductal carcinoma positive for estrogen receptor and progesterone receptor, and negative for HER2/neu protein expression. She received 4 cycles of CEF (E: 60 mg/tri-weekly) plus 12 cycles of paclitaxe (l80 mg/weekly). After chemotherapy, she received muscle preserving mastectomy plus axillary lymph nodes dissection. In histopathology, there were no carcinoma cells in resected breast tissue and resected lymph nodes. Therefore, the effect of chemotherapy was diagnosed as a pathological complete response. After operation, she was administered aromatase inhibitor. The patient has been well and remained disease-free during a follow-up period of 6 years.     

Is It Contralateral Axillary Metastasis or Occult Breast Cancer?: A Confusing Case Report

We report the case of a 43-year-old woman with primary left breast cancer presenting metastatic lymphadenopathy in the contralateral axilla. This patient represents a diagnostic and therapeutic challenge because primary breast cancer, occult contralateral breast cancer, and extra-mammary primary lesion can all be the source of the contralateral axillary metastasis. Left breast-conserving surgery, left sentinel lymph node biopsy, right breast mass excision, and right axillary lymph node dissection were performed. Immunohistochemical analysis revealed that the left breast cancer specimen was positive for estrogen receptor (ER) and progesterone receptor (PR), but negative for human epidermal growth factor receptor 2 (HER2). In contrast, the right axillary lymphadenopathy specimen was negative for ER and PR, but positive for HER2. Further investigation revealed no evidence of occult primary cancers or extra-mammary tumors. After surgical intervention, the patient was treated with adjuvant chemotherapy, adjuvant radiation therapy, and targeted therapy with trastuzumab. Two years after diagnosis, she is free of disease and presently being treated with tamoxifen.Key Words: Breast carcinoma, Occult primary tumor, Contralateral axillary lymph node metastasis, Immunohistochemistry     

Surgical resection for elderly patient with skin invasion of breast cancer

We report a locally advanced elderly breast carcinoma with skin invasion. The patient was a 96-year-old woman who had a breast lump. The palpable tumor was 3 .5 cm in diameter. Ultrasonography revealed a low echoic mass. A core needle biopsy for the breast tumor led to a diagnosis of an invasive ductal carcinoma positive for estrogen receptor and progesteron receptor, and negative for HER2/neu protein expression. She underwent a tumorectomy including the cancer invasive skin by local anesthesia. Because her respiratory function was unbearable to perform a muscle-preserving mastectomy with general anesthesia. The surgical margins of the resected specimen were negative. The clinicopathological stage, according to the UICC-pTNM classification, was Stage III C (T4b, N0, M0). After the operation, she was administered aromatase inhibitor. The patient has been well and remained disease-free during a follow-up period of 3 years. The surgical excision with local anesthesia was useful for locally advanced super senior breast cancer patients who were impossible to perform general anesthesia by various kinds of factors.     

Locally advanced breast cancer with a good response to sequential endocrine monotherapy--a case report

An 81-year-old woman with a right breast tumor exposed through the skin surface visited our clinic in June 2004. Pathological findings of the resected tumor specimen indicated invasive ductal carcinoma of the breast,positive ER/PgR status,and negative HER 2/neu status. The enlarged right axillary lymph nodes were palpable. Ultrasonography and computed tomography revealed that the tumor invaded the chest wall without any metastasis to remote organs. On July 5, 2004, we started anastrozole treatment. Its effects were confirmed in the first month,and the treatment was continued for 8 months. Substituting anastrozole with exemestane was not effective. However, the exposed part of the tumor completely responded to tamoxifen that was administered for 2 months. The effect of tamoxifen continued until February 2006, and most of the subcutaneous part of the tumor became nonpalpable. Thus, sequential endocrine monotherapy proved useful for an elderly woman with locally advanced breast cancer.     

A case of secretory carcinoma of the breast in a elderly Japanese woman

We report a case of a secretory carcinoma of the breast in a 72-year-old woman with a long history of a left breast mass. Rapid growth and skin invasion of the tumor was noticed three months before a radical mastectomy was performed and a lung metastasis was found one month after the operation. A metastasis to the axillary nodes was noted in 6 of 9 resected specimens and a receptor assay of the estrogen and progesterone proved to be negative. This patient is the oldest case of a secretory carcinoma of the breast reported in Japan.     

Isolated retromammary lymph node metastasis of breast cancer without axillary lymph node involvement: a case report with a false-negative sentinel lymph node biopsy

A 54-year-old woman visited our hospital with a palpable tumor in her left breast, which was diagnosed as invasive ductal carcinoma. Breast-conserving surgery was performed, in association with a sentinel lymph node (SLN) biopsy and back-up dissection of the axillary lymph nodes. One dyed axillary lymph node with high radioactivity was defined as an SLN, and intraoperative frozen-section analysis of the SLN was negative for metastasis. The final pathological diagnosis of the tumor was invasive ductal carcinoma, and one small lymph node, located in the retromammary space, just under the tumor, was positive for metastasis. The backup axillary lymph nodes were not metastatic. This patient was diagnosed false-negative by SLN biopsy, despite being positive for retroMLN metastasis. It should be recognized that retroMLNs are difficult to detect preoperatively, or intra-operatively, using dye or radiocolloid, if they are located in the post-tumoral retro-mammary space. RetroMLNs may be a pitfall in SLN biopsies.     

Sentinel Node Biopsy in Early Breast Cancer Patients with Palpable Axillary Node

Background: Sentinel lymph node biopsy is a reliable method for evaluation of the axillary lymph node status in early stage breast cancer patients with non-palpable lymph nodes. The present study evaluated the status of sentinel and non-sentinel lymph nodes in T1T2 patients with palpable axillary lymph nodes. Materials and Methods: One hundred and two women with early breast cancer were investigated in this study. Patients were selected for axillary sentinel lymph node biopsy and then surgery .Then the rates of false negative and true positive, and diagnostic accuracy of sentinel lymph nodes biopsy were evaluated. In addition, the hormone receptors status of the tumor was determined through IHC and data was analyzed in SPSS21. Results: In this study, the mean age of the patients was 49 years, 85% had invasive ductal carcinoma  in their pathology reports, 77% were ER/PR positive, 30% HER2 positive and 9.8% triple negative and 69% had KI67<14%. In frozen pathology, 15.7 and 84.3% were sentinel positive and negative, respectively, and in the final pathology, 41 and 58.8% were sentinel positive and negative, respectively. This difference arises from the false negative rate of the frozen pathology, which was about 31.3%. The sensitivity, specificity, and diagnostic accuracy of the frozen section were 24, 90 and 43%, respectively. Lymphovascular invasion is an important effective factor in the involvement of sentinel and non-sentinel lymph nodes. Statistical analysis showed that the probability of sentinel and non-sentinel lymph nodes involvement was higher in receptor positive patients and those with KI67>14% (p<0.002) whereas the rate of involvement was lower in triple negative patients. Conclusion: Sentinel node biopsy can be used in a significant percentage of breast cancer patients with palpable and reactive axillary lymph nodes.     

Scalene node excision biopsy in advanced prostate carcinoma

In 12 patients with disseminated prostate carcinoma, supraclavicular lymph node biopsy was performed. In 3 patients with palpable supraclavicular node, tumor cells were found in the lymph nodes. In the remaining 9 in whom there were no palpable nodes, unilateral left scalene lymph node excision biopsy revealed no evidence of tumor cells in the nodes in spite of diffuse bone metastasis. These findings suggest that unilateral scalene node biopsy did not provide additional information and has no advantage over the known parameters in staging of prostatic cancer.     

A case of breast cancer diagnosed by inguinal lymph node metastasis

We describe a case of a 58-year-old woman with right inguinal lymph node swelling and a T1 tumor in the right breast. She was referred with an 18-month history of the former complaint and a six-month history of the latter. Excisional biopsy of the inguinal lymph node revealed breast cancer metastasis. Radiographical examination showed no metastases to the lungs, liver or bone. Modified radical mastectomy was performed. Histological examination revealed solid tubular carcinoma, PT2, PM (axillary lymph node metastases 4/16), stage IV. Estrogen and progesterone receptors were negative. Three cycles of postoperative cyclophosphamide, adriamycin and 5-fluorouracil (CAF) chemotherapy were given, and the right inguinal area was irradiated with 40 Gy. The patient complained of swelling in both legs three years after surgery. Computed tomography revealed marked lymph node swellings in the pelvic cavity. She died six months later. Inguinal lymph node metastasis from breast cancer is very rare, although distant lymph node metastasis in the cervix occurs frequently. This case should help clarify how breast cancer metastasizes to distant lymph nodes.     

Intracystic invasive papillary carcinoma of the male breast with analyses of loss of heterozygosity on chromosome 16q

A 64-year-old man noticed a right subareolar mass in May 2005. On physical examination, an oval-shaped, well-circumscribedthe tumor (6.0 × 5.5 cm in size) was located just beneath the right nipple. The tumor was elastic, firm and freely movable. Neither axillary nor supraclavicular lymph nodes were palpable. Mammography demonstrated a 5 × 5-cm, relatively distinct and dense mass without microcalcifications or spiculations. There were no findings of concurrent gynecomastia. Ultrasonography revealed a large multilocular cyst with a mural hypoechoic protruding lesion exhibiting wide-based morphology with an irregular margin. On contrast-enhanced computed tomography, the inner lesion enhanced, but direct invasion of the tumor to the major pectoral muscle was not found. An intracystic papillary lesion, possibly papillary carcinoma, was suspected. In December 2007, wide excision of the tumor was performed. On histopathological examination, the tumor had a papillary pattern with a small cribriform component in the cystic wall with microinvasion of the stroma. Marginal status was negative. The final diagnosis of the disease was a microinvasive intracystic papillary carcinoma of low grade without axillary lymph node metastases. Immunohistochemically, estrogen receptor and progesterone receptor were both positive, but negative for HER-2 protein. No LOH on 16q could be detected. The prognosis of the disease was unclear; however, the malignant potential of this condition may be more clearly determined by studying the LOH on chromosome 16q.     

Stromal sarcoma with features of giant cell malignant fibrous histiocytoma

We report a case of primary giant cell malignant fibrous histiocytoma (GCMFH) of the breast. A 56-year-old Japanese woman presented with a firm mass in the right breast. Mammography and ultrasonography revealed a well-circumscribed and lobulated mass in the upper outer quadrant of the right breast, indicative of a benign breast tumor or mucinous carcinoma. Magnetic resonance imaging revealed a restricted breast tumor without intraductal spread. Computed tomography and bone scintigraphy found no sites of distant metastases. Fine needle aspiration biopsy showed several clusters of atypical cells associated with numerous multinucleated giant cells. Breast-conserving surgery with axillary lymph nodes dissection was performed. Histological examination showed primary GCMFH of the breast. No metastases were identified in any of the 15 left axillary lymph nodes resected and surgical margins were free from tumor cells. The tumor was negative for both estrogen and progesterone receptor. Neither adjuvant chemoendocrine therapy nor postoperative radiotherapy was given, and the patient has remained disease free for 30 months postoperatively. To our knowledge, only 30 cases of primary MFH of the breast have been reported in the literature.     

A non-invasive form of lipid-secreting carcinoma of the breast

Lipid-secreting carcinoma is a rare variant of breast carcinoma. The tumor cells possess abundant vacuolated cytoplasm containing neutral fat. A 68-year-old Japanese female patient presented with a left breast tumor, which was detected by mass screening, and she was admitted to our hospital. The physical examination revealed an elastic hard lump in the left lateral quadrant of the left breast. The tumor size was 1.2 × 1.0 cm in diameter and the borderline was unclear. There were no palpable axillary lymph nodes or supraclavicular nodes. Mammography showed a polygonal mass with microcalcification. Ultrasonography indicated a hypoechoic lesion measuring 9 × 4 mm in diameter, with an irregularly shaped, slightly indistinct surface. The internal echoic level of the mass was heterogenous. Enhanced magnetic resonance imaging revealed a mass of high intensity in the left breast, and the connection of the intraductal spread was not detected. The time–intensity curve showed a peak-and-plateau pattern. Fine-needle aspiration cytology suggested a malignant tumor. The patient underwent a partial resection of the left breast (breast-conserving therapy) and a left axillary lymphadenectomy. Macroscopically, the resected specimen revealed a white tumor measuring approximately 0.6 × 0.5 cm. Histopathologically, the tumor measured up to approximately 0.9 × 0.7 cm because of additional components of intraductal spread and therefore was diagnosed as an extensive ductal carcinoma in situ with focal mass formation; the tumor also had abundant foamy cytoplasm. Oil-red-O staining confirmed the presence of marked cytoplasmic lipid droplets. These droplets were periodic acid–Schiff (PAS) negative even after diastase digestion, and negative with PAS–Alcian blue staining. In immunohistochemistry, these carcinoma cells were positive for E-cadherin. Thus, the pathological diagnosis was a non-invasive form of lipid-secreting carcinoma. The tumors were negative for both estrogen receptors and progesterone receptors. There were no metastases in the left axillary lymph nodes. The patient has remained well for 8 years without any evidence of recurrence.     

A case of phyllodes tumor with bloody nipple discharge in juvenile patient

We report a rare case of phyllodes tumor of the breast in a juvenile patient with bloody nipple discharge. An 11 -year-old girl had a chief complaint of a palpable 5 cm well-circumscribed tumor with nipple discharge in the left breast. The histopathological diagnosis of the resected specimen was benign phyllodes tumor showing extensive areas of hemorrhagic necrosis. The bloody nipple discharge was caused by spontaneous infarction of the tumor. Preoperative ultrasonography and galactography were helpful in evaluating the mechanism of nipple dicharge from the tumor. Although phyllodes tumor must be differentiated from fibroadenoma, the present case was histopathologically identical to phyllodes tumor.     

Pathogenesis and treatment of Paget's disease of the breast

Fifty cases of Paget's disease of the breast treated surgically at The Johns Hopkins Hospital during the past 30 years were studied. Nineteen patients had Paget's disease confined to the nipple and 31 had an associated palpable tumor. An underlying intraductal or infiltrating duct carcinoma of the breast was present in each case. In six cases, the underlying tumor was 2 cm or more from the nipple with no apparent anatomic connection to the Paget lesion, and one case was encountered in whom intradermal Paget's disease develop in the area of a congenitally absent nipple. These findings support the theory of an intradermal origin for the Paget cell. Survival rates of patients with Paget's disease and a palpable breast mass were similar to those of patients with infiltrating duct carcinoma, the presence of axillary node metastases being the most important prognostic factor. Actuarial five- and ten-year survival rates were 22% and 9.9% for patients with positive nodes. The modified radical mastectomy is recommended as primary therapy for this group of patients. In contrast, none of the patients with Paget's disease of the nipple and no evidence of a palpable breast mass developed recurrent carcinoma. A total mastectomy without an axillary node dissection is the treatment of choice in this type of patient.     

A case report of lipid-rich carcinoma of the breast including histological characteristics and intrinsic subtype profile

A 57-year-old Japanese woman with schizophrenia, who had received long-term treatment with neuroleptics, noticed a painless, pea-sized lump in her right breast. She was admitted to our hospital and a malignant tumor was diagnosed. The patient underwent a conservative radical mastectomy (Patey's operation). The excised tumor measured 2.0 × 1.2 × 1.1 cm in diameter, and its cut surface was grayish-white. Histologically, tumor cells with clear to foamy cytoplasm were invariably Oil Red O-positive and periodic acid Schiff-negative with or without diastase digestion. The tumor was diagnosed as a lipid-rich carcinoma accompanied by an in situ component. Neuroleptics increase serum prolactin levels by interfering with dopaminergic inhibition of prolactin secretion. Immunohistochemical analysis revealed that, although prolactin was not detected, the tumor cells expressed prolactin receptor, indicating prolactin as the genesis of this neoplasm. In immunohistochemical intrinsic subtype analysis, the tumor was negative for estrogen receptor, progesterone receptor, human epidermal growth factor receptor 1 and 2, and basal cytokeratins (CK5, CK6, and CK14), indicating an unclassified (all-marker negative) subtype. Axillary lymph nodes were free of metastasis (stage I), and the patient has been well for 20 years without any evidence of recurrence.
