Practical Review of Ovarian Sex Cord-Stromal Tumors

摘要

Ovarian sex cord-stromal tumors are uncommon tumors and clinically differ from epithelial tumors. They occur across a wide age range and patients often present with hormone-related symptoms. Most are associated with an indolent clinical course. Sex cord-stromal tumors are classified into 3 main categories: pure stromal tumors, pure sex cord tumors, and mixed sex cord-stromal tumors. The rarity, overlapping histomorphology and immunoprofile of various sex cord-stromal tumors often contributes to diagnostic difficulties. This article describes the various types of ovarian sex cord-stromal tumors and includes practical approaches to differential diagnoses and updates in classification.
