Porokeratosis. Two morphologic forms within a family

Disseminated superficial actinic porokeratosis co-existing with linear and verrucous porokeratosis in an elderly woman: Update on the genetics and clinical expression of porokeratosis

“…[7][8][9][10][11][12][13][14][15][16][17][18] When an individual has isolated linear porokeratosis, often there are family members with DSAP. 11,19 Our patient had DSAP on the distal extremities, linear porokeratosis on the lateral thighs, and verrucous porokeratosis on the buttocks and mons pubis.…”

Porokeratosis of Mibelli and superficial disseminated porokeratosis

“…Reported cases of mixed PK types, mostly involving disseminated superficial actinic PK and linear PK, affected either individuals 11–24 or families 11,12,25,26 . Only three cases of PK of Mibelli were described in association with another PK type, i.e.…”

Linear Porokeratosis in Two Families with Disseminated Superficial Actinic Porokeratosis

“…The common characteristic of these clinical variants is the presence of the cornoid lamella in histologic sections (4).…”

“…There have been several reports of more than one type of porokeratosis occurring in the same family (4)(5)(6)(7) or the same individual (6)(7)(8)(9). We wish to highlight the variable expressivity of this dominantly inherited condition by describing two additional cases of linear porokeratosis occurring in patients whose family members have DSAP.…”

“…Linear porokeratosis and disseminated, superficial, actinic porokeratosis (DSAP) are included in the current classification of porokeratosis (Table 1) (1). The common characteristic of these clinical variants is the presence of the cornoid lamella in histologic sections (4).…”
