Resumen

. El reticuloide actínico es una fotodermatosis crónica propia de edades avanzadas que se caracteriza por la presencia de pápulas y placas eritemato-edematosas que evolucionan a máculas pigmentadas residuales, localizadas al inicio en zonas fotoexpuestas y en relación con la exposición a la luz diurna.

Describimos un caso típico de esta rara entidad en un varón de 70 años, seguido de forma periódica en nuestro servicio por presentar frecuentes exacerbaciones de su cuadro clínico que consiste en eritema, edema y descamación junto con signos de dermatitis actínica crónica en zonas fotoexpuestas que evolucionan a pápulas eritemato-escamosas muy pruriginosas. El diagnóstico se realizó a través de la historia clínica, la característica evolución en brotes y tras constatar que las lesiones cutáneas empeoraban tras exposición a fuentes de energía radiante.

Consideramos que esta entidad es debida a una extrema sensibilidad a un amplio espectro de radiación y posiblemente forme parte de la dermatitis actínica crónica.

Summary

. Actinic reticuloid is a chronic photodermatosis which is typical of elderly patients and that is characterized by the presence of papules and erythematous-edematous plaques that evolve into residual pigmented macula which are located, in the beginning, in sun-exposed areas and in relationship to the exposure to daytime light.

We describe a typical case of this rare entity in a 70 year old male patient followed-up periodically by our service due to frequent exacerbations of his clinical picture. This consists in erythema, edema and desquamation together with signs of chronic actinic dermatitis in sun-exposed zones that evolve to erythematous-scaly papule with intense itching. The diagnosis is carried out through the clinical history, the characteristic evolution in episodes and after verifying that the cutaneous lesions worsen after exposure to radiant energy sources.

We consider that this entity is due to an extreme sensitivity to a wide radiation spectrum and possibly forms a part of chronic actinic dermatitis.
