Abstract

Introduction: Neuroendocrine carcinomas mainly affect the bronchopulmonary and the gastrointestinal systems. Primary neuroendocrine carcinomas of the breast are rare, with incidence under 0.1% from all the breast carcinomas and under 1% from all neuroendocrine carcinomas.Case: We present a case of 85-year-old woman diagnosed with primary neuroendocrine carcinoma of breast. Patient primarily treated as benign breast lump pre-operatively and Simple Mastectomy was done. On histopathological examination patient diagnosed with primary neuroendocrine carcinoma of breast.Discussion: Neuroendocrine breast carinoma is a rare type of breast cancer. Diagnosis made mainly on basis of histopathological examination and immuno histochemical markers. Due to its rarity and lack of randomized data, there is little evidence to guide the choice of treatment. Consequently, neuroendocrine carcinomas of the breast is currently treated as any invasive breast carcinoma not-otherwise specified. Surgery is the mainstay of the treatment for early neuroendocrine carcinomas of the breast.Result: A rare case of Neuroendocrine breast carcinoma was diagnosed post-operatively on histopathological examination. Patient had underwent Simple Mastectomy as pre-operatively treated as benign breast lump and post-operative follow-up was uneventful.
