A Case of an Inflammatory Pseudotumor of the Uterus Diagnosed After Laparoscopic Surgery

Abstract

Background: Inflammatory pseudotumor is a tumor-like mass of inflammatory origin. It is most commonly found in the lung or the orbit, but occurrences have been reported at nearly every site in the body. These tumors most commonly appear in young and middle-aged patients.
Case: A 37-year-old female presented with vaginal bleeding and anemia. Ultrasound and MRI showed a myoma like mass of 56 mm in maximum diameter at the posterior wall of the uterine body. Preoperative hormone therapy failed to shrink the mass. Histological examination of the mass following laparoscopic enucleation revealed spindle shaped mesenchymal cells with infiltration by inflammatory cells, consistent with inflammatory pseudotumor. Smooth muscle cells were seen scantily in the margins of the resected mass.
Conclusion: A rare inflammatory pseudotumor of the uterus is diagnosed after laparoscopic surgery.
