Primary small cell neuroendocrine carcinoma of vagina: a rare case report.

Primary small cell neuroendocrine carcinoma of vagina is an extremely rare disease. There have been only 26 previously reported cases in literature. Here, we report a case of primary small cell neuroendocrine carcinoma of vagina. Immunohistochemistry (IHC) showed tumor cells positive for synaptophysin, chromogranin, and neuron-specific enolase (NSE).
