Epidermoid cyst of the testis is rare benign tumor, and its differential diagnosis from malign testicular tumors is difficult.

The lesion was diagnosed as epidermoid cyst after histopathologic examination and treatment options of epidermoid cyst which is a rare reason of testicular tumor was presented and discussed through the literature.
