title: Transfollicular extrusion of sebaceous glands: natural phenomenon or artifact? A case report.
abstract: A sebaceous gland tumor on the back of a 28-year-old man underwent periodic exudation of yellowish material in association with local irritation. Pathological examination revealed entire sebaceous gland lobes lying subcorneally in the orifices of sebaceous follicles. This case appears to represent transfollicular extrusion of sebaceous gland lobes as a natural phenomenon rather than as an artifact.
