    Parasitic leiomyoma is a rare subtype of uterine leiomyoma that can occur outside the uterus, often deriving blood supply from adjacent organs.

    Iatrogenic parasitic leiomyoma has become more common due to unconfined morcellation during laparoscopic surgeries, complicating diagnosis.

    A 38-year-old female with a history of laparoscopic myomectomy presented with abdominal pain, initially misdiagnosed as a gastrointestinal stromal tumor.

    Surgical resection revealed the mass to be a parasitic uterine leiomyoma, confirmed by histopathological examination.
