Progressive dermoscopy of palmoplantar syphilides

An unusual palmoplantar pigmentation.

A 60 year old man had asymptomatic progressive pigmentation of the palms (fig 1), fingertips (fig 2), and soles for the last 20 years. Besides this, he had discoloration of his sclerae (fig 3). He was well but for low backache and joint pains of a few months’ duration. Histopathological examination of the skin lesion was diagnostic (fig 4). Questions (1) What is your diagnosis?

Dermoscopy of chromoblastomycosis

Chromoblastomycosis is a chronic cutaneous fungal infection commonly caused by Fonsacea and Cladophialophora spp. Dermoscopy is a non-invasive, real-time diagnostic tool for rapid bedside diagnosis of various inflammatory and non-inflammatory disorders and can be an excellent modality for evaluation of cutaneous mycosis, for which it shows characteristic brown dots, crust, scales and yellow ora...

Dermoscopy of Pitted Keratolysis

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...
