A very rare localization of a rare disease: palmar lichen nitidus

Abstract

Lichen nitidus is an uncommon lichenoid dermatosis that could be defined as multiple, separated, shiny, pinpoint, pale to skin-colored papules. Palmoplantar lichen nitidus is a quite rare variant of lichen nitidus. It is hard to make a diagnosis of palmar lichen nitidus when there are no lesions elsewhere on the body. There are some dermoscopic features defined for both palmoplantar and non-palmoplantar lichen nitidus that might be useful to facilitate the diagnosis before histopathological examination. Herein, we report a case of a 24-year-old man diagnosed with isolated palmar lichen nitidus with dermoscopic features and histopathological confirmation.

Dermoscopy of palmoplantar keratoderma: development and analysis methods

“…In the palmoplantar variant, parallel thick linear scales discontinuous by well-defined oval depressions and surrounded by ring-shaped silvery-white scales have been described [23,24]. The axis of the depressed pattern and that of the linear scales are parallel [23,25] (Fig.…”

A case report of lichen nitidus and its dermoscopic features

“…Durusu et al reported a case of palmar lichen nitidus, with a dermoscopic picture of fine round to ovoid comedo-like central depression areas surrounded by white halo-like scales and white linear scales connecting the whole structure [9].…”
