Undifferentiated carcinoma of the ovary

Radswiki et al.

An undifferentiated carcinoma of the ovary is a rare type of ovarian epithelial tumour. They account for ~ 4% of ovarian cancer 2.


With these tumours, cellular differentiation is not sufficient for the tumour to be categorised into serous, mucinous or other specified subtypes. Pure undifferentiated carcinomas are rare; most of these tumours are mixed, with areas of serous, glandular, or transitional cell differentiation.


All undifferentiated carcinomas are malignant. Most of these tumours are diagnosed at a late stage and have a poor outcome.
