Small Cell Neuroendocrine Carcinoma of the Endometrium

International Journal of Gynecological Pathology, 1995
Ten cases of endometrial small cell neuroendocrine carcinoma are described. The ages of the patients ranged from 50 to 75 years (mean, 64 years). Most of the tumors were bulky, intraluminal masses that invaded at least half of the myometrial wall. Small cells were the only malignant element in two tumors. In the other eight, there were admixed elements

Small cell neuroendocrine carcinoma of the ovary

Virchows Archiv, 1997
A 64-year-old woman (gravida 0, para 0) had a unilateral ovarian mass measuring 14 cm in its greatest diameter, which was mostly solid. Microscopically, the tumour was characterized by two predominant proliferating patterns: a carcinoid-like pattern with trabecular, tubular, glandular, or insular arrangements and a closely packed nesting pattern with ...

Small cell neuroendocrine carcinoma of the rectum

Pathology International, 1995
Poorly differentiated small cell neuroendocrine (NE) carcinoma of the colon and rectum is a rare primaty epithelial malignancy at this location. A case of a highly aggressive NE tumor of small cell type, combined with non‐invasive well‐differentiated papillary adenocarcinoma in villous adenoma is reported.

Small Cell Neuroendocrine Carcinoma of the Eyelid

Ophthalmic Plastic & Reconstructive Surgery, 2008
This is a case presentation of a rare primary small cell neuroendocrine carcinoma of the eyelid. This tumor was diagnosed and differentiated from Merkel cell carcinoma using histopathology, immunohistochemistry, and electron microscopy.

Small Cell Neuroendocrine Carcinoma of the Nasopharynx

Journal of Craniofacial Surgery
Background: Nasopharyngeal malignant tumors were relatively rare head and neck tumors with a low global incidence. There were various pathologic types of nasopharyngeal malignant tumors, and small cell neuroendocrine carcinoma (SCNEC) was a highly malignant subtype with rapid growth and early metastasis.

Mechanisms of Neuroendocrine Differentiation in Pulmonary Neuroendocrine Cells and Small Cell Carcinoma

Endocrine Pathology, 2003
We review the significance of a network of proneural basic helix-loop-helix (bHLH) factors. Immunohistochemically, pulmonary neuroendocrine cells (PNECs) are positive for Mash1, one of the activator bHLHs, and non-PNECs such as Clara cells are positive for Hes1, one of the repressor bHLHs. Since mice deficient for the Mash1 gene do not possess PNEC and

Neuroendocrine small cell carcinoma of the uterine cervix

Clinical and Translational Oncology, 2010
Neuroendocrine small cell carcinoma of the uterine cervix (SCC) is a rare disease that mixes clinical and biological characteristics of both cervical neoplasms and neuroendocrine small cell cancer. The prognosis is poor and the optimal treatment has not yet been clarified. Multimodality treatment, with surgery and concurrent chemoradiation has recently

Small cell undifferentiated (‘neuroendocrine’) carcinoma of the colon

Histopathology, 1990
Three patients are described who presented with a large colonic adenoma in which a solid, undifferentiated carcinomatous component was found on microscopic examination. Despite small size (1.0 and 1.5 cm) and submucosal location in two cases, the tumours had metastasized to regional lymph nodes and the liver and death ensued at 4, 11 and 18 weeks after

Small Cell Neuroendocrine Carcinoma of Bartholin's Gland

American Journal of Clinical Pathology, 1990
A small cell neuroendocrine carcinoma that arose in Bartholin's gland in a 30-year-old woman is reported. The tumor had light, electron microscopic, and immunohistochemical features typical of pulmonary small cell carcinoma and was metastatic to inguinal lymph nodes at presentation.

Metastatic small cell neuroendocrine carcinoma of the breast

Journal of Cutaneous Pathology, 2012
Cutaneous metastases from internal malignancies in women overwhelmingly emanate from the breast and typically exhibit features of an adenocarcinoma, although other histopathologic patterns may also be seen. Neuroendocrine breast carcinoma represents an uncommon variant of mammary carcinoma with fewer than 40 cases of the small cell subcategory reported.
