Keratosis pilaris rubra with mucin deposition.
J Cutan Pathol. 2018 Dec; 45(12):958-961.JC

Abstract

Keratosis pilaris (KP) is a benign cutaneous disorder characterized by folliculocentric hyperkeratotic papules most often occurring on the proximal extremities. Erythema is usually limited to perifollicular skin, but when keratosis pilaris presents on a background of confluent erythema, the term keratosis pilaris rubra (KPR) is used. The histological findings associated with KP have not been well described in the literature. Herein, we present a case of a 14-year-old male with a 7-year history of erythema and follicular-based papules over his bilateral cheeks, consistent with KPR. Histological examination revealed abundant mucin, keratotic follicular plugging, and periadnexal lymphocytosis. Our novel finding of abundant dermal mucin expands the histopathologic description of KPR.
