Neuroendocrine tumours (NETS) are rare tumours. The commonest site of occurrence is the gastrointestinal tract. NETS in the breast are even rarer, accounting for less than 0.1% of all breast cancers and less than 1% of all NETS. We are reporting a case of primary neuroendocrine carcinoma of the breast in a 60 years old female. Investigations were done to rule out any other associated lesion. Patient was treated by modified radical mastectomy and adjuvant chemo and radiotherapy.
