Neuroendocrine Carcinoma of the Breast: Case Report and Literature Review

Background: Neuroendocrine carcinoma of the breast is a rare disease. Case Report: We present a 65-year-old female patient with an enlarged breast mass within 2 months. Solid neuroendocrine carcinoma of the breast was diagnosed by excision biopsy and histopathological analysis. A lumpectomy with the right axillary sentinel lymph node biopsy was performed, and the mass was completely resected. The literature on neuroendocrine carcinoma of the breast is reviewed. Conclusion: Due to the diversity of imaging findings from primary breast neuroendocrine carcinomas, the diagnosis is based on immunohistochemical staining of neuroendocrine markers. Surgery has turned out to be the first-line treatment and subsequently radiation may play a role in palliative treatment.
