Abstract:

Uterine inflammatory myofibroblastic tumor (UIMT) is an extremely rare mesenchymal tumor with intermediate biological potential. It is easily misdiagnosed at the initial presentation, with the risks of recurrence and metastasis. We report a case of a 54-year-old woman who underwent laparoscopic total hysterectomy with bilateral salpingectomy at another hospital after a uterine mass was detected. Six months after surgery, she developed abdominal distension and discomfort. Examination at our hospital suggested the recurrence of the pelvic tumor with pulmonary metastasis. She underwent an open pelvic adhesiolysis and pelvic mass resection, and the pathological diagnosis was inflammatory myofibroblastic tumor. The patient refused further treatment, and the tumor progressed more than two months after surgery. The diagnosis of UIMT mainly relies on immunohistochemical analysis and supplementary molecular testing. Accurate preoperative diagnosis is helpful for formulating a treatment plan, with the aim of improving the survival rate.
