[A case of giant epidermoid cyst occupying the testis].
A case of a giant epidermoid cyst of the testis is presented. A 65-year-old man was incidentally pointed out to have left scrotal painless swelling. Physical examination revealed an over hen-egg sized enlargement of the left scrotal contents. Ultrasonography revealed a 7.5 X 5.5 X 4.0 cm solid tumor with heterogeneous echogenicity. No other abnormal findings were observed including tumor markers. Since preoperative examination did not rule out malignancy, we performed left high orchiectomy. Pathological diagnosis was a epidermoid cyst of the testis with a small portion of atrophic testis. Although the preoperative diagnosis of testicular epidermoid cyst is possible, it may be considerably difficult when a giant epidermoid cyst is occupying the testis.
