Undifferentiated carcinoma of the ovary
An undifferentiated carcinoma of the ovary is a rare type of ovarian epithelial tumor. They account for ~ 4% of ovarian cancer 2.
With these tumors, cellular differentiation is not sufficient for the tumor to be categorized into serous, mucinous or other specified subtypes. Pure undifferentiated carcinomas are rare; most of these tumors are mixed, with areas of serous, glandular, or transitional cell differentiation.
All undifferentiated carcinomas are malignant. Most of these tumors are diagnosed at a late stage and have a poor outcome.
