Abstract
Pityriasis Rubra Pilaris is a rare, chronic, mildly inflammatory disease characterized by fine acuminate follicular papules with orange-red to salmon-colored scaling of the skin and erythroderma that surround islands of normal, uninvolved skin, particular in the trunk. Most patients also develop palmoplantar hyperkeratosis in the early course of the disease.
Focal acantholysis occurring in pityriasis rubra pilaris is an unusual and incidental histologic finding within the spectrum of histologic change of the disease. No case featuring this concomitant histologic finding has been reported in the Korean literatures up to date.
We report a case of focal acantholysis occurring in a patient with the clinical features of pityriasis rubra pilaris which may be considered as an incidental finding.
