This orchiectomy specimen from an adult male shows an epidermoid cyst. It is filled with yellow-white keratinous material with a hint of concentric or lamellar arrangement. The surrounding testis appears normal and did not show any atypia or germ cell neoplasia-in-situ upon extensive sampling.
- are not associated with germ cell neoplasia-in-situ
- lack cytologic atypia
- do not show chromosome 12p amplification
- are not associated with gonadal dysgenesis, microliths, or parenchymal scarring
- behave in a benign fashion with no risk of recurrence and metastasis
- can be appropriately treated with conservative (testis-sparing) approach
