TLDR The term "Porokeratotic Adnexal Ostial Nevus" is suggested as a more appropriate name.
The document discussed two cases of rare adnexal hamartomas, specifically Porokeratotic Eccrine Ostial and Dermal Duct Nevus (PEODDN) and Porokeratotic Eccrine and Hair Follicle Nevus (PEHFN). Both cases involved young patients with asymptomatic papular lesions arranged in a linear pattern, with histological features including focal hyperkeratosis, acanthosis, and cornoid lamella overlying eccrine acrosyringia or hair follicle ostia. The study suggested that PEODDN and PEHFN might represent a single entity, proposing the term "Porokeratotic Adnexal Ostial Nevus" (PAON) as a more appropriate nomenclature. Various treatments have been used with variable success, reflecting the challenges in managing these conditions.
