Small cell neuroendocrine carcinoma
Corpus uteri


A neuroendocrine carcinoma composed of small malignant cells which histologically often resemble "oat cells". Clinically, this is often a rapidly growing cancer that spreads to distant sites early.

Small cell carcinoma of the uterine corpus is an uncommon endometrial carcinoma. The prognosis is far better than for small cell carcinomas elsewhere in the female genital tract; 5-year survival for stage I disease is about 60%
