Abstract

Nodular histiocytic and mesothelial hyperplasia (NHMH) is a rare and benign proliferative lesion composed of histiocytes with scattered mesothelial cells which was first reported in hernia sac by Rosai and Dehner in 1975 [1]. They described NHMH as a “benign reactive condition simulating a neoplastic process [1].” Since then, several cases have been reported in lung, pleura, inguinal region, urinary bladder, and pelvic cavity [2-9]. We report a case of incidentally detected NHMH, presenting as a pelvic nodule during laparoscopic surgery for uterine myoma and endometriosis.
