Bilateral breast metastasis from pancreatic neuroendocrine tumor: A diagnostic challenge

Abstract

Metastatic neuroendocrine tumors to breast are very rare with less than 30 cases reported worldwide. The first case was reported in 1957 according to literature. Among these 13 cases reported as breast lump as initial presentation. As the tumor is not so common, the radiological features are not well defined leading to misdiagnosis. Bilateral breast metastasis from pancreatic neuroendocrine tumors has not been mentioned in the literature. Here, we present a case of pancreatic neuroendocrine tumor with metastasis to bilateral breast.
