Abstract
Microcystic stromal tumor of ovary (MCST) is a rare ovarian sex cord-stromal tumor. This paper presents a case of a 47-year-old female who was admitted to the hospital due to occasional lower abdominal pain and subsequently diagnosed with Microcystic stromal tumor of the left ovary. No recurrence or metastasis was observed after 60 months of treatment. Moreover, all reported clinicopathological features, treatment methods, and prognoses of MCST patients are reviewed herein.
