A Late Recurrent Metastatic Breast Cancer Mimicking Primary Pancreatic Cancer: Case Report.

Metastasis to the pancreas from malignant tumors is a rare event, representing only 1% to 2% of all pancreatic neoplasms. They occur in 2 different clinicopathological settings: as a manifestation in widespread metastatic disease or as an isolated mass in the pancreas. We report the case of a 41-year-old woman who had a history of invasive lobular breast cancer treated with radical surgery, chemotherapy, and radiotherapy. After 21 years of total remission, she presented for severe lower back pain with jaundice, nausea, and loss of 9 kg in 3 months. Abdominal computed tomography demonstrated a hyper vascularized, irregular solid lesion of 2.6 cm × 2.1 cm in the head of the pancreas with discreet biliary duct dilatation and coelio-mesenteric enlarged lymph nodes measuring 2 cm. The diagnosis of pancreatic metastasis from a lobular breast carcinoma was made by percutaneous biopsy of pancreatic lesion. The multidisciplinary committee decided a palliative treatment. The patient received chemotherapy. The take home message from his case is that we should keep in mind the hypothesis of a solitary metastasis to the pancreas, when the pancreatic lesion develops in a patient who had a clinical history of previous neoplasm especially in those which is known to potentially metastasize to pancreas.

Primary myxofibrosarcoma of the male breast: A case report

Myxofibrosarcoma is an unusual type of malignant fibrous histiocytoma that arises in subcutaneous tissue in the limbs of elderly patients and uncommonly involves the breast.We report a rare case of myxofibrosarcoma that occurred in a male breast. A 57-year-old man was referred to our department for a right breast mass. Physical examination revealed an irregular lump without skin involvement. Ultrasonography and mammography showed an oval and hypoechoic opacity with increased internal vascularity. The patient had a core needle biopsy that showed a sarcoma of the breast. The patient underwent a simple mastectomy. The pathology report confirmed the diagnosis of high-grade myxofibrosarcoma of the breast and the patient had local radiotherapy. After a follow-up of 18 months, the patient has no evidence of local recurrence or distant metastases. Myxofibrosrcoma of the breast is extremely rare but should be diagnosed as soon as possible because of the rapid growth of the tumor and the better prognosis in the early stages.
