OBJECTIVE: To report a case of premature ovarian failure (POF) associated with an ovarian sex cord tumor with annular tubules. DESIGN: Case report. SETTING: Reproductive endocrinology unit in a tertiary academic center. PATIENT(S): A 20-year-old woman with POF. INTERVENTION(S): Biopsy of the rudimentary ovary by laparoscopy. MAIN OUTCOME MEASURE(S): Protocol for POF investigation and histological study of the ovarian sample. RESULT(S): An ovarian sex cord tumor with annular tubules was detected in the rudimentary right ovary. CONCLUSION(S): The rare ovarian sex cord tumor with annular tubules, which may be hormonally active, was detected in a case of POF.
