Pelvic clear cell adenocarcinoma in a young man: a case report

Clear cell adenocarcinoma is a relatively common neoplasm in the female genital tract, which can also occur in the bladder and urethra. In men, it is a rare neoplasm . We describe the case of a young man with large pelvic mass and diagnosed as clear cell adenocarcinoma. The patient had increased serum levels of CA 125 and carcinoembryonic antigen (CEA) . The tumor was immunohistochemically positive for CA 125 and CK7 and negative for PSA and CK20. Due to the size of the neoplasm at diagnosis and the morphological, immunohistochemical and clinical characteristics, the probable histogenetic origins of the tumor are prostate, prostatic urethra or seminal vesicle.
