Undifferentiated carcinoma of the endometrium is rare histological subtype of endometrial cancer. It is considered a high grade carcinoma, carries a poor prognosis and is often under-recognized 1.
It is thought to represent approximately 1-9% of endometrial cancers 1,6.
They have no evidence of glandular or epithelial differentiation. They can be further sub divided into large cell, intermediate or small cell types. Some of carcinomas carry neuroendocrine expression 4.
