Dermoscopy of pitted keratolysis


Lockwood, L L; Gehrke, S; Navarini, A A (2010). Dermoscopy of pitted keratolysis. Case Reports in Dermatology, 2(2):146-148.

Abstract

Irritated hyperhidrotic soles with multiple small pits are pathognomonic for pitted keratolysis (PK). Here we show the dermatoscopic view of typical pits that can ensure the diagnosis. PK is a plantar infection caused by Gram-positive bacteria, particularly Corynebacterium. Increases in skin surface pH, hyperhidrosis, and prolonged occlusion allow these bacteria to proliferate. The diagnosis is fundamentally clinical and treatment generally consists of a combination of hygienic measures, correcting plantar hyperhidrosis and topical antimicrobials.
