sebaceoma; sebaceous epithelioma; Sebazeoma
DefinitionThis section has been translated automatically.
Controversial term (especially in the Anglo-American language area) for adnexal tumors with differentiation of sebaceous glands, which show only a moderate degree of differentiation. Nosologically they are located between the sebaceous adenoma and the sebaceous carcinoma. Sebaceous epitheliomas often occur in a sebaceous nevus.
ManifestationThis section has been translated automatically.
Predominantly occurring after the age of 50. Men are more frequently affected than women.
