RESUMO
El lupus eritematoso sistémico (LES) del anciano, también llamado lupus de aparición tardía,es una enfermedad autoinmune que aparece después de los 50-60 años, con un curso clínicoy manifestaciones clínicas que difieren del LES clásico, cuya prevalencia es en personas másjóvenes, predominantemente mujeres. Se presenta, en este artículo, el caso de un pacientemasculino de 72 años con cuadro clínico de un mes de evolución de dolor en hemitóraxderecho, tipo pleurítico asociado a disnea, además de la presencia de lesiones eritematosasy descamativas en región malar y zona de exposición solar en tórax. Se descartó origeninfeccioso y neoplásico mediante imágenes diagnósticas y laboratorios y, posteriormente,se realiza perfil inmunológico que reporta ANAS positivo, Anti-DNA positivo y complementoconsumido, con evidencia de derrame pleural derecho masivo recidivante hasta la fecha.
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.

Hemorrhagic cystitis is potentially life-threatening sequellae of chemotherapy using oxazaphosphorine alkylating agents (cyclophosphamide and ifosfamide). Mesna contains a sulfhydryl group that is believed to bind acrolein within the urinary collecting system and reduce the hemorrhagic cystitis without affecting the chemotherapeutic potential. To date, about thirty cases of hypersensitivity or allergic reactions of the delayed and urticarial type associated with mesna have been reported. We reported two patients with systemic lupus erythematosus who developed facial rash and flushing associated with mesna which imitate malar rash.
