A case of palmar lichen nitidus presenting as a clinical feature of pompholyx

Abstract

Lichen nitidus (LN) is an uncommon chronic eruption of an unknown cause, and it is characterized by tiny, discrete, flesh-colored papules. The sites of predilection are the genitalia, trunk and extremities. Unilateral palmar involvement with pruritus is infrequent. We report here on a case of LN confined to the right palm, and the patient presented with multiple, pruritic, erythematous to flesh-colored, tiny papules and vesicles that mimicked pompholyx. The histopathological examination of a skin biopsy specimen showed the typical findings of LN.
