RationaleFibrothecomas are benign ovarians tumors. These are solid sex-cord-stromal tumors, accounting for 1% to 4.7% of all ovarian neoplasms. Their recurrence rate is known to be only 2% following ovarian sparing local mass excision. We report an uncommon case of 2 pelviscopic resections of fibrothecomas originating from the left ovary with recurrence after 10 years in a 34-year-old woman.Patient ConcernsA 34-year-old married woman was diagnosed with 41 mm sized left ovarian recurrent fibrothecoma. We performed mass excision pelviscopically the first time 10 years ago. She gave birth to her second baby at 7 years after the first surgery. Ten years after the first surgery, fibrothecoma recurred on the same ovary with size larger than before.DiagnosesAt the time of its first occurrence 10 years ago, the ultrasound scan revealed a 34 × 23 mm-sized solid hypoechoic mass with well-demarcated margins and minimal Doppler flows. Ultrasound findings at the time of recurrence 10 years later showed the same findings, with its size increased to 41 × 40 mm. Final pathologic findings showed left ovarian fibrothecoma.InterventionsAfter her admission to the hospital, we performed pelviscopic removal of left ovarian fibroma. Microscopic examination revealed predominantly bland spindle cells with collagenous stroma, showing fascicular and storiform growth.OutcomesSurgeries were successful. The patient had been followed-up regularly for 3 years after last surgery. She did not experience any complications. She remained disease-free.LessonsRepetitive local mass excision appears to be an effective surgical option in women of reproductive age. Although there is a sufficient possibility of recurrence several years to decades after only mass excision, mass excision is more appropriate than total oophorectomy in women of childbearing age. Pelviscopic surgery is recommended.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
