Synchronous metastases to the liver and pancreas from a primary neuroendocrine carcinoma of the breast diagnosed by fine-needle aspiration.
Extrapulmonary neuroendocrine carcinoma is uncommon. Cases of primary neuroendocrine carcinoma of the breast have been reported, though rare. We report the case of a 53-year-old woman who underwent a mastectomy for breast carcinoma and presented three years later with synchronous masses in the head of the pancreas and liver. Fine-needle aspiration of both organs revealed a neuroendocrine carcinoma. The original breast tumor was reviewed and found to express neuroendocrine markers. A diagnosis of a primary neuroendocrine carcinoma of the breast was rendered.
