Abstract

The adenomatoid tumor is rare benign neoplasm in genital tract which is involving both sexs. In male patient the tumors are frequently found in epididymis and tunica vaginalis, while in female patients they are usually located in the fallopian tube but may also be found in the uterus and ovary. Grossly, they are well circumscribed without encapsulation, firm, with whitish-yellow cut surface which is moist and glistening. Microscopically, the tumor is composed of abundant cystic spaces or lymphatic channels including some unclearly defined acinar or glandular structure lined by cells, designated by various authors as endothelial, mesothelial, or epithelial like cells within fibrous background. Only a few cases of adenomatoid tumor have been reported in Korea. As we experienced a case of adenomatoid tumor in epididymis and a brief review of adenomatoid tumor was also made.
