Outcome of conservative laparoscopic surgery for adnexal torsion through one-stage or two-stage operation.

AIM: We investigated the outcome on ovarian appearance and occurrence of adhesion after conservative laparoscopic surgery for adnexal torsion during reproductive age. MATERIAL AND METHODS: From April 2009 to September 2012, we treated patients with clinically suspected adnexal torsion who desired future pregnancy. We performed conservative surgery, such as cystectomy or detorsion at one-stage operation, but switched to salpingo-oophorectomy in complicated cases. We evaluated adnexal condition and pattern of adhesion by careful assessment with two-stage laparoscopy or second-look laparoscopy after first surgery. RESULTS: Mean age of patients was 25 ± 8 years. Among 37 patients with suspected adnexal torsion, 18 (49%) had adnexal torsion at first surgery. Conservative treatment was carried out in 14 of 18 cases. We obtained informed consent for second-look laparoscopy or two-stage operation in six of these 14 cases. Among these six patients, two cases were treated with only detorsion by one-stage operation and cystectomy was performed in the other four cases at first operation. At subsequent surgery, the ovary appeared normal in six cases with occurrence of mild to moderate adhesion around the adnexal lesion. Of note, two cases with para-ovarian cyst had torsion that showed complete tubal occlusions and associated severe adhesions. No major complications (peritonitis, thrombotic emboli) were observed after conservative laparoscopic surgery. CONCLUSION: Conservative laparoscopic surgery is a safe procedure to preserve ovarian function in women with adnexal torsion. Careful attention and measures should be considered during follow-up management with the fact in mind that adhesion is a common occurrence and even tubal occlusion may occur in some cases.

Rapid growth of mitotically active cellular fibroma of the ovary: a case report and review of the literature.

BACKGROUND: Mitotically active cellular fibroma (MACF) of the ovary, characterized by relatively high mitotic activity without severe atypia, represents a relatively new disease entity. MACF is categorized as a benign ovarian tumor. However, due to a limited number of case reports, its clinical and pathological features and optimum management remains largely undetermined. Herein, we report on a rare case of MACF that grew rapidly in size and was diagnosed on detailed pathological examination. CASE PRESENTATION: A 44-year-old Japanese woman, who detected a myoma-like lesion 1-year earlier, was referred to our hospital when the follow-up examination demonstrated that the mass had increased in size. Magnetic resonance imaging revealed a T1 isointense and T2 hyperintense tumor (11 cm in diameter) in the right pelvic cavity. Laparoscopy confirmed the presence of a right ovarian tumor and laparoscopic right adnexectomy was performed. The tumor cells consisted of dense cellular proliferations of spindle fibroblast-like cells without significant cytological atypia. The mitotic activity index was estimated at >15 mitotic figures per 10 high-power fields. Reticulin staining and FOXL2 mutation analysis excluded the possibility of an adult granulosa cell tumor, and the patient was diagnosed with a MACF of the ovary. CONCLUSIONS: To the best of our knowledge, we are the first to report on a case of rapid growth of a MACF of the ovary during follow-up. When an increase in the size of a solid ovarian mass is detected, a MACF should be considered as a differential diagnosis.
