Keratosis lichenoides chronica (KLC), AKA Nekam's disease, is a very rare disorder characterized by a papular eruption taking on linear and reticulate shapes.

Clinical

Violaceous, lichenoid, hyperkeratotic, linear bands, often in a reticulated pattern. It is usually more prominent on the extremities and tends not to be pruritic. Many but not all patients have a seborrheic dermatitis-like eruption of the scalp. The course is chronic. One case thought to be KLC clinically turned out to be CTCL [BJD 1998;138;1067]. It is important to exclude lichen planus, lichen simplex chronic, and lupus among others. Some have proposed that KLC is merely a curious morphologic manifestation of some of the above conditions.

Treatment

Some patients have responded well to PUVA. Oral retinoids have also had some success. Calcipotriol once daily for 4 months resulted in marked clinical improvement in one patient.
