Epididymal Leiomyoadenomatoid Tumor: A Case Report and Review of Literature

Primary tumors of the epididymis are rare. Adenomatoid tumors are benign, usually found within the wall of fallopian tubes or beneath the uterine serosa. They are most frequently diagnosed as benign tumors of the epididymis and represent 30% of paratesticular tumors. The origin of this tumor is mesothelial cells. Leiomyoma are less common in the paratesticular localization. The origin of this tumor is smooth muscle cells. Clinically, these tumors are indistinctive with a painless mass of the scrotum. Here, we reported a case of combined leiomyoadenomatoid tumor. The histogenesis of this lesion remains unknown. This entity can be the result of a collision of the two tumors, or it can be a subtype of adenomatoid tumors with smooth muscle hyperplasia. This case showed the difficulty that occurs in the identification of this kind of lesion. Only one case of this entity in the epididymis was described in the literature. Leiomyoadenomatoid tumor is a benign neoplasm. In our case, this lesion was surgically removed in toto and no recurrence was observed.Curr Urol 2013;7:195-198
