Pityriasis Rubra Pilaris is an inflammatory papulosquamous and hyperkeratic dermatosis of unknown cause and chronic progression which can envolve even into erythroderma. This case deals with a 27-year old male patient carrier of VIH who was diagnosed with PRP type IV. Initially, it was treated with topical corticosteroid and phototherapy for four months. However, it showed reactivation of the injuries; therefore, excimer lamp was employed, which is used in other dermatologic pathologies but it is not a regular treatment for PRP type IV.

Palabras clave : Excimer lamp pitiriasis rubra pilaris (PRP)- Lymphoma; T-Cell; Cutaneous type Mycosis Fungoides tipomicosis - Virus de inmunodeficienciahumana (VIH).
