Description

Neuroendocrine tumors (NET) frequently originate in the GI tract and lung tissue. They often metastasize to the liver and lymph nodes. Tumors of the GI tract will most commonly metastasize to the liver through drainage from the portal venous system. When these do metastasize, enterochromaffin cells in NETs secrete serotonin which can lead to symptoms such as flushing, diarrhea, and sequela of right sided heart disease. These tumors can be misdiagnosed, particularly when they present in infrequent locations such as breast tissue. Prompt and accurate diagnosis of NETs is essential in guiding proper management. Here, we present a rare case of a GI tract NET primary metastasizing to the breast.
