Lupus eritematoso sistémico en el anciano: una presentación atípica de una enfermedad común

Systemic lupus erythematosus (SLE) in the elderly, also called late-onset lupus, is an autoimmune disease that appears after 50-60 years old, with a clinical course and clinical manifestations that differ from classic SLE, with a prevalence predominantly in younger women. In this article a case of a 72 year-old male patient who, for one month, had clinical symptoms of right chest pain, associated with dyspnea and the presence of erythematous and scaly lesions on the malar area and sun exposure in the thorax. The possibilities of infectious or neoplastic origin were dismissed using diagnostic images and laboratory tests. An immunological profile was subsequently performed, reporting positive ANAS and Anti-DNA, positive, and consumed complement, with evidence of recurrent massive right pleural effusion to date.
