Uterine leiomyoma mimicking a gastrointestinal stromal tumor with chronic spontaneous hemorrhage: A case report

Abstract

Uterine leiomyomas are the most common tumors to affect women. Cases of uterine leiomyoma mimicking a gastrointestinal stromal tumor with chronic spontaneous hemorrhage are extremely rare, and similar cases to that of the present study are yet to be reported. In the current study, a 48‑year‑old female presented with symptoms of lower abdominal pain after menses that had persisted for 4 months. The patient was initially diagnosed with uterine leiomyoma. However, according to the results of the gross and auxiliary examinations, a diagnosis of a gastrointestinal stromal tumor could not be excluded. Therefore, the patient underwent a rectal sigmoid bowel resection, subtotal hysterectomy and bilateral salpingectomy. Subsequent to surgery, the immunohistochemical examinations confirmed the initial diagnosis of uterine leiomyoma. The surgery had therefore involved an unnecessary organ resection.
