Kerinokeratosis Papulosa of Childhood

Boris Bauer et al. Dermatology. 2015.

Abstract

Background: Kerinokeratosis papulosa (KP) is considered an extremely rare genodermatosis presenting usually as waxy papules on the trunk in childhood.

Objective: To describe and analyze the clinical, histological and potential etiopathological aspects of KP.

Methods: The dermatoscopic features of a new case of KP of childhood are investigated. The presence of human papillomavirus (HPV) DNA in lesional skin was studied by polymerase chain reaction. Furthermore, all cases of KP of childhood reported so far were reviewed.

Results: As a diagnostic tool, we describe for the first time a dermatoscopic feature, namely a cribriform pattern of KP, in an 11-year-old boy. In addition, we detected HPV (type 57) in his KP lesions.

Conclusions: Dermatoscopic examination might be a useful tool to distinguish KP from other skin lesions, e.g. common warts. The detection of HPV type 57 might hint to an etiological role of HPV for KP.
