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.
