title: [A case of giant epidermoid cyst of the testis].
abstract: A 79-year-old man visited our clinic with complaints of left scrotal swelling. Ultrasonography revealed solid tumor with heterogeneous echogenicity. No other abnormal findings were observed including tumor markers. However, the tumor was very large and the diagnosis of malignant testicular tumor could not be excluded. Therefore, orchiectomy was performed. Histological diagnosis was 820-gram epidermoid cyst of the left testis.
