RESUMO
Toxic epidermal necrolysis is a potentially fatal disease due to allergic reactions to drugs. We report on a 58 years old female, that presented Raynaud sphenomenon during 20 years. During the last year, she developed polyarthritis of hands, shoulders, knees and ankles. Rheumatoid factor (RF), antinuclear antibodies (ANA) and U_ ribonucleoprotein (U1 RNP) were present, and Mixed connective tissue disease was suspected. Because of a poor response to methotrexate the patient received leflunomide. Two weeks later, she began with fever, pruritus and generalized edema. Within days this affected her neck, thorax, eyes and oral mucous. She had bullaes and areas of epidermic detachment. A toxic epidermal necrolysis was diagnosed and treated with IV immunoglobulins. The lesions disappeared successfully. In addition to the dermatological problem, the patient later presented ocular complications that required the transplant of both corneal, with the sub-sequent loss of one of her eyes.

La neumonitis inducida por sales de oro fue descripta por primera vez en 1960. Existen pocos casos bien documentados reportados a la fecha. Se describe un interesante caso de injuria pulmonar difusa reversible, desarrollada en una paciente con artritis reumatoidea en curso terapeútico con sales de oro. El desarrollo de síntomas respiratorios poco tiempo después de la aparición de un rash cutáneo típico inducido por oro, la ausencia de compromiso pleural, la respuesta favorable a la administración de corticoterapia y la interrupción de las sales de oro sugieren el diagnóstico.
