Metastatic tumors to the breast are rare in adults. Melanomas, lymphomas, and gastrointestinal primaries are the most common sources of metastasis. We describe a female patient with a history of pancreatic insulinoma nd bilateral breast masses proved to be metastatic insulinomas on CT-guided biopsy. A nuclear medicine scan and special immunohistochemical stains were utilized to distinguish the lesions from a primary breast neoplasm.
