Trichilemmal Cyst Nevus with a Sebaceous Nevus Component

A 23-year-old man with a typical trichilemmal cyst nevus is reported. This recently described disorder is sufficiently characteristic to differentiate it from sebaceous nevus, nevus comedonicus, porokeratotic eccrine nevus, nevus corniculatus, follicular basaloid hamartoma, Munro's nevus and Gardner's syndrome.
