Primary neuroendocrine small cell carcinoma of the breast
A 60-year-old Turkish woman presented with a left breast mass, which was considered for neoadjuvant chemotherapy. By the end of the treatment cycles, the tumor had decreased in size, and the patient underwent modified radical mastectomy with axillary lymph node dissection. Pathologic examination of the tumor revealed a small cell carcinoma with neuroendocrine features confirmed by immunohistochemical stains. Multiple axillary lymph nodes were involved by metastatic small cell carcinoma carrying the same morphologic characteristics noted in the primary breast tumor. We hereby present this case as a primary neuroendocrine small cell carcinoma of the breast. This entity occurs very rarely in the breast, and fewer than a dozen cases have been reported in the literature. Extrapulmonary small cell carcinoma of the breast is reportedly a very aggressive tumor for which no consensus for treatment has yet been drawn.

- "Despite no current line of management being agreed upon, neo-adjuvant chemotherapy should be carried out, because it is conducive to decrease tumor size. The roles of chemotherapy drugs etoposide and cisplatin have also been proved in the adjuvant scheme for treating SCNC of the breast.18 When this regimen was used in the neoadjuvant setting, the size of this SCNC subtype was decreased.

ABSTRACT: In this case study and review, we present a case of a primary small-cell neuroendocrine carcinoma (SCNC) of the male breast. Primary SCNC of the breast is a rare tumor with less than 30 cases reported in the literature. Most cases are found in women. Another exceptional point is that human epidermal growth factor receptor-2 (Her-2) immunoreactivity was positive in our recent case, which differed to previous reports detailing SCNC in women. We have no evidence to demonstrate the differences between treatment and prognoses for males and females, because we do not have sufficient cases to undertake an evidence-based investigation. We provide this rare case history; review the literature on SCNC of the breast; and discuss detailed information regarding epidemiology, histogenesis, clinical and histologic diagnosis criteria, surgical and adjuvant treatment, and prognosis.

- "Generally, this tumor is considered clinically aggressive with dismal prognosis. As observed in this case, previous authors have also reported rapid progression or recurrence of this disease locally and distally, and a short survival period (1, 4, 6, 15). However, as in breast carcinoma of the usual type, size is a very important prognostic factor for this tumor (3). "

ABSTRACT: Primary neuroendocrine carcinoma of the breast is a very rare malignant tumor. There are not many cases reported in the English literature since it was first documented in 1983. Reports on the imaging features, in particular the ultrasonographic features of this rare tumor are scarce. Herein, we report a case of aggressive primary infiltrating neuroendocrine carcinoma of the breast, masquerading as an inflammatory breast condition in a 22-year-old young lady, perhaps the youngest case ever reported in the English literature. We discuss the imaging features and highlight the Doppler ultrasonographic findings of this rare breast carcinoma. This is the first documentation on Doppler ultrasonographic findings of primary neuroendocrine carcinoma of the breast in the literature.
