Objective: The authors report a rare case of female adnexal tumor of probable Wölffian origin ( FATWO), presenting with acute ovarian torsion and treated by laparoscopic surgery while preserving fertility in a young woman. Case Report: A 30-year-old woman was referred to this clinic for evaluation of an adnexal mass. The tumor was found to have originated from the right tubal fimbria and had torqued three times. When the frozen section proved negative for malignancy, a right salpingectomy was performed. Based on the pathological and immunohistochemical findings, the final diagnosis was concluded to be a FATWO. Adjuvant therapy was not administered because the patient wanted to preserve her fertility. No evidence of recurrence has been observed during the past five years. Conclusion: Fertility preserving treatment should be considered in young women with FATWO.
