  Fig. 1. (A) On axial computed tomography, a solid and cystic mass (arrows) with periuterine adhesions is visible in the left adnexa. (B) Another mass can be seen in the left upper abdominal wall (arrows) and extending to the rectus abdominis muscle. A small amount of ascites is present in the perihepatic area (arrowheads). (C) Microscopically, the mass is composed of endometrial-like tissue. Dilated endometrial-type glands are longitudinally arranged around grouped, thick-walled vessels with swollen and congested stroma, which is reminiscent of a typical endometrial polyp. (D) Some glandular epithelial cells demonstrate ciliated metaplasia. (E) On immunohistochemical staining, the glandular epithelial cells and some stromal cells are positive for estrogen receptor. (F) CD10 is positive only in stromal cells.
