Keratosis Pilaris

Initial Evaluation

Keratosis pilaris

Lichen spinulosus

Lichen spinulosus, a condition often seen in children, likely represents a clinical variant of KP in which typical lesions seen in KP (e.g., monomorphous hyperkeratotic papules with a central spicule) are arranged in nummular patches at sites not typically affected by KP. Hyperpigmentation of the papules or hyperkeratotic plug is common.

Differential diagnosis
