It presents as a chronic evolution and produces high morbidity and mortality in countries where the disease is endemic, as in ours. The skin disease is very rare and results from the reactivation of latent disease as a result of immunosuppression, presenting with acute, atypical, and severe lesions. We describe the case of a patient who was unaware of being a carrier of Chagas disease and presented reactivation after immunosuppressive therapy instituted to treat her systemic lupus erythematosus. *Department of Dermatology †Department of Medical Microbiology and Parasitology ‡Department of Rheumatology, Clínicas Hospital, Faculty of Medical Sciences, National University of Asuncion, Paraguay.
