A Case of Porokeratotic Eccrine Ostial and Dermal Duct Nevus of Childhood Onset

• Yoo HD

Abstract

Porokeratotic eccrine ostial and dermal duct nevus is considered to be a rare congenital hamartoma of eccrine duct origin. Histopathologic studies showed multiple cornoid lamella-like parakeratotic columns, which were associated with hyperplastic eccrine ostia and distal sweat ducts. I describe the case of a 20-year-old man with childhood-onset porokeratotic eccrine ostial and dermal duct nevus. He had a 10-year history of multiple keratotic papules and comedo-like pits on the thenar area and thumb of the right hand. But in my case, immunohistochemical studies for carcinoembryonic antigen showed no association with eccrine ostium and adjacent cornoid lamella-like structures.
