Abstract

Lichen nitidus (LN) is a chronic inflammatory condition characterised by multiple asymptomatic shiny, flat-topped, pale to skin-coloured tiny papules. LN occurs most often in children and young adults with limbs, abdomen, chest, and penile shaft as common sites of predilection. Nail involvement is rare and includes irregular longitudinal grooving and ridging of the nail plate. We report two cases of generalised LN with nail dystrophy in 8- and 12-year-old boys along with the treatment response and review the pertinent literature.

Keywords: Intramatricial injection; Lichen nitidus; Onychodystrophy.
