Primary Mammary Small Cell Carcinoma.

Neuroendocrine breast cancer was defined in 2003 by WHO as a separate and unique breast cancer subtype. Primary small cell carcinoma of the breast, an exceptionally uncommon and aggressive tumor, is frequently characterised by early progression and worse outcome. Moreover, it is essential to distinguish between small cell carcinoma arising primarily in the breast and the metastatic disease to the breast.
