Infundibular keratosis--report of two cases.
Two cases of infundibular keratosis are presented, characterized histopathologically by funnel-shaped, invaginating, epithelial lobules showing infundibular keratinization and connection with pilosebaceous structures. Lightly-staining, glycogen-laden epithelial cells predominated within the two tumors. Differential diagnoses with other infundibular tumors and relationships to trichilemmoma are discussed.
