Paratesticular epidermoid cyst and ipsilateral spermatic cord dermoid cyst: case report and discussion of pathogenesis, diagnosis and treatment.

We report a case of a paratesticular epidermoid cyst with a concurrent dermoid cyst of the ipsilateral spermatic cord at the internal inguinal ring. The patient presented for evaluation of a presumed testicular neoplasm. Epidermoid and dermoid cysts were confirmed histologically after local excision. To our knowledge concomitant occurrence of these lesions has not been reported previously. We discuss the pathogenesis, diagnosis and treatment.
