Localized actinic nasal porokeratosis

Localised nasal actinic porokeratosis: An independent subtype of porokeratosis?

“…Interestingly, this case had gross similarity to the single largest published series (12 female and 3 male patients) [1] and the subsequent individual case reports of nasal PK [5,[7][8][9].…”

Pruritic papules on the nose in a 25-year-old female

“…This might represent a distinct subset of PM related to actinic damage, and the term localized actinic nasal porokeratosis had been suggested. [3]…”

Follicular porokeratosis at alae nasi; A case report and short review of literature

“…[5] There have been a few reports of exclusive facial involvement in porokeratosis, with skin lesions mostly over or near the nose. [1678910] Follicular involvement, identified by follicular localization of cornoid lamellae, is uncommon and described only in association with other subtypes such as DSAP, PM, and exclusive follicular cornoid lamella in follicular porokeratosis. [411]…”

“…[12] These are believed to be genodermatoses with an autosomal dominant mode of inheritance. [1] Porokeratosis is characterized by annular plaques with an atrophic center and hyperkeratotic edges clinically, although it has a wide variety of clinical manifestations.…”

“…[12] These are believed to be genodermatoses with an autosomal dominant mode of inheritance. [1] Porokeratosis is characterized by annular plaques with an atrophic center and hyperkeratotic edges clinically, although it has a wide variety of clinical manifestations. The various morphological types recognized are: Porokeratosis of Mibelli (PM) disseminated superficial actinic porokeratosis (DSAP), porokeratosis palmaris et plantaris disseminata (PPPD) and linear porokeratosis (LP).…”
