'''Thecomas''' or '''theca cell tumors''' are [[benign]] [[Ovarian cancer|ovarian neoplasm]]s composed only of [[theca cell]]s. Histogenetically they are classified as [[sex cord-stromal tumour]]s. 

They are typically [[estrogen]]-producing and they occur in older [[women]] (mean age 59; 84% after [[menopause]]). (They can, however, appear before menopause.<ref name="pmid15327450">{{cite journal  |vauthors=Okada I, Nakagawa S, Takemura Y, etal |title=Ovarian thecoma associated in the first trimester of pregnancy |journal=J.
