title: Laparoscopically resected uterine adenomatoid tumor with coexisting endometriosis: case report.
abstract: Adenomatoid tumors are rare benign mesothelial tumors of the genital tract, and only a few cases of uterine adenomatoid tumors treated at laparoscopic surgery have been reported. Herein is reported the case of a laparoscopically resected uterine adenomatoid tumor with coexisting endometriosis. A 34-year-old nulliparous woman with suspected uterine fibroma and endometrial cysts underwent laparoscopic surgery in which both the uterine tumor and the endometrial cysts were enucleated. Enucleation of the uterine tumor was difficult, and, therefore, the border between the tumor and normal myometrium was divided using a harmonic scalpel for tumor resection. Microscopic examination of the tumor showed irregularly proliferating smooth muscle cells and many round hiatuses lined by epithelial-like cells. These epithelial-like cells were immunohistochemically positive for mesothelin and podoplanin, and negative for CD34, which suggests that the tumor was an adenomatoid tumor. This may be the fourth reported case of an adenomatoid tumor resected using the laparoscopic approach.
