Widespread presentation and spontaneous regression of porokeratotic eccrine ostial and dermal duct nevus

A case of porokeratotic adnexal ostial nevus misdiagnosed as wart

“…PAON typically presents as multiple linear hyperkeratotic papules or punctate pits on extremities, most often at birth or in early childhood. 4,5 Upon review of the literature, at least 81 cases of PEODDN have been reported but many of these cases had their onset at birth, unlike our case. 3 An association with deafness, hemiparesis, hyperthyroidism, polyneuropathy, and seizures has been reported, but the relationship remains uncertain and most patients with PAON are otherwise healthy.…”

Bilateral systematized porokeratotic eccrine ostial and dermal duct nevus

“…Few cases with spontaneous involution have been described. [ 7 ] Small and localized lesions are suitable candidates for surgery. Ultra-pulse CO 2 laser is an acceptable therapy because the chances of scarring and pigmentary changes are minimal.…”

Adult‐onset papular hyperplasia of eccrine glands associated with clear cells: is it a new entity?

“…Miliaria rubra displays small, red and intensely itchy papules without sweating, and is due to obstruction of sweat ducts that is always caused by heat and high humidity. PEODDN, a rare nevoid hamartoma of the eccrine sweat glands, is characterized by asymptomatic grouped keratotic papules and plaques with a linear pattern on the extremities, and distinct porokeratotic histopathological hallmarks [11,12]. SSPS, caused by mutations of WNT10A, may be associated with benign acanthoma, apocrine and eccrine hidrocystomas, eccrine poroma, follicular infundibulum tumors and milia etc.…”
