| pubmed-article:3787857 | pubmed:abstractText | An epidermoid cyst of the testis is a rare benign lesion, representing about 1% of all testicular tumors. Most of the lesions occur between the age of 20 and 40 and present as a painless enlargement of the testis, or are found as a nodule on routine examination. Histopathologic findings consist of a cyst filled with keratin and lined by a squamous epithelium. There is evidence that this tumor is of germ-cell origin and represents monoepidermal differentiation of a benign teratoma. There is some discussion about treatment, but most authors perform radical orchiectomy. | lld:pubmed |
