Abstract
Abstract—Keratosis lichenoides chronica is an uncommon cutaneous disorder of unknown ethiopathogenesis. It is clinically characterized by the presence of hyperkeratotic papules spread through the trunk and extremities adopting a linear and/or reticular pattern. A facial eruption, suggestive of seborrheic eczema, is frequently associated.A 44-year-old male presented cutaneous lesions characteristics of keratosis lichenoides chronica for more than 10 years. The histological study confirmed the clinical suspiction. A treatment with calcipotriol ointment, applied twice a day, was prescribed. Eight weeks later, a partial improvement, with a thinning of the lesions and erythema remission, was observed.There is not a treatment for this disease. The best results have been obtained by PUVA and etretinate therapy. Recently, the effectiveness of the topical calcipotriol has been reported. In our case, a satisfactory improvement of the lesions, according to the patient, was obtained without complete remission. We believe that calcipotriol is a valid alternative for these patients, especially when systemic treatments involve a risk.
