Abstract
While the metastatic spread of breast cancer is well documented, the breast is seldom a site for metastasis. Non-mammillary cancers can involve the breast or axilla, though this is exceedingly rare with few reported instances. Here, we present the case of a 62-year-old woman who attended an outpatient breast clinic with a history of an ileal carcinoid tumor complicated by multi-organ metastasis. Her disease was in clinical remission for several years, though she recently re-presented with a single solitary lesion to the breast that was later confirmed as a recurrence of her carcinoid tumor. This serves as an important reminder that the breast can indeed be a site for metastasis. As metastatic breast lesions can often be difficult to diagnose, it is essential to obtain a thorough medical history in order to determine the appropriate clinical course.
