Erupción fija por luz solar, una serie de 13 casos en Bogotá, Colombia / Fixed Sunlight Eruption: A Series of 13 Cases in Bogotá, Columbia

Desde 1975 se han publicado algunos casos que asocian la radiación ultravioleta como un desencadenante de erupciones cutáneas fijas (erupción o exantema fijo por luz solar o síndrome de fotosensibilidad localizada de amplio espectro). Describimos los casos de 13 pacientes con esta dermatosis, 4 varones (30,8%) y 9 mujeres (69,2%), con edades comprendidas entre los 28 y los 56 años, atendidos en un centro de referencia en dermatología en Bogotá, Colombia. Las lesiones se localizaron en la cara interna de los muslos, los glúteos, la región poplítea, la axilar anterior y posterior y el dorso de los pies. La prueba de fotoprovocación logró la reproducción de las lesiones en todos los casos en las áreas afectadas y la histopatología reveló cambios similares a los descritos en los eritemas fijos por medicamentos. Esta enfermedad podría corresponder a un subtipo de erupción fija, aunque no se descarta que sea una dermatosis diferente con una patogenia común.(AU)

Few reports describing an association between UV radiation and fixed skin eruptions have been published since 1975. These reactions have received various names, including fixed sunlight eruption, fixed exanthema due to UV radiation, and broad-spectrum abnormal localized photosensitivity syndrome. We present a series of 13 patients (4 men [30.8%] and 9 women [69.2%]) aged between 28 and 56 years who were evaluated for fixed eruptions induced by UV radiation at a dermatology referral hospital in Bogotá, Colombia. The lesions were located on the inner thighs, buttocks, popliteal region, anterior and posterior axilla, and dorsum of the feet. Photoprovocation reproduced lesions in all the affected areas, and histopathology showed changes similar to those seen in fixed drug eruptions. While these UV-provoked reactions may be a type of fixed skin eruption, we cannot rule out that they may also be a distinct condition that simply shares a pathogenic mechanism with fixed eruptions.(AU)
