Primary leiomyosarcoma of the fallopian tube (PLFT) is an extremely rare gynecological malignancy that has only been described in case reports. Fertility-sparing treatment for PLFT has not been reported previously. A 24-year-old nulligravida woman was diagnosed with stage IC1 PLFT in the right fallopian tube after experiencing right lower quadrant pain for 2 weeks. She underwent laparoscopic right salpingectomy to preserve fertility followed by adjuvant chemotherapy with gemcitabine/docetaxel. She subsequently became pregnant spontaneously, delivering a term baby 27 months after treatment. This appears to be the only report of the use of fertility-preserving treatment for PLFT. The success of the treatment provides valuable information on the preservation of fertility in young women with PLFT.
