Neurofibromatosis 1 (NF1) patients are generally at higher risk of developing common malignant tumors such as brain and soft tissue tumors. These patients are 5-fold increased the risk of developing breast cancer by the age of 50 years after that the risk remains the same. The most common reported cancer is infiltrating duct carcinoma. We report a case of 61-year-old female with NF1 presented with pain and breast lump for the past 2 months. On mammography, a retroareolar solid cystic lesion measuring 32 mm × 30 mm × 30 mm was noted which was definitive for malignancy. Right-modified radical mastectomy with axillary lymph node dissection was done which revealed a neoplasm composed of glandular and squamous components. Immunohistochemically, these cells were triple negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2-neu and expressed markers of basal cell differentiation. The final pathological staging was T2N0M0. This is the fourth case report in the English literature with such association. In this case report, we discussed the importance of breast cancer screening in such patients along with a review of the literature.
Hepatoid adenocarcinoma lung (HAL) is an extremely rare type of extrahepatic adenocarcinoma with morphological similarity to hepatocellular carcinoma. We report a case of 59 years male smoker who presented with anorexia, weight loss and cough. Chest X-ray revealed a homogenous opacity in the left upper and mid zone. Computed tomography (CT) chest showed a left upper lobe mass with enlarged hilar lymph nodes. Serum alpha fetoprotein (AFP) was normal. Guided fine needle aspi ration cytology (FNAC) of the mass revealed a few atypical cells. Endobronchial biopsy showed sheets of polygonal cells with coarsely clumped chromatin, eosinophilic nucleoli and abundant eosinophilic to clear cytoplasm. The neoplastic cells were positive for hepatocyte-1, Carcinogenic embryonic antigen (CEA), Cytokeratin 7 (CK-7) and cytoplasmic positivity for thyroid transcription factor (TTF-1). After 3 months, the tumor had grown significantly. Due to its aggressive behavior, early and accurate diagnosis is necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
