Preferred Label : thecoma;
RADLEX synonyms : fibrothecoma;
Definition : A gonadal stromal neoplasm composed only of theca cells, occurring mostly in the postmenopausal
ovary. It is filled with lipid-containing spindle cells and produces estrogens that
can lead to endometrial hyperplasia; uterine hemorrhage; or other malignancies in
postmenopausal women and sexual precocity in girls. When tumors containing theca cells
also contain fibroblasts, they are identified as thecoma-fibroma tumors with less
active hormone production. [MeSH];
