Lobular panniculitis of the thigh as the only cutaneous manifestation of reactivation of Chagas disease in a renal transplant patient: a case report

Abstract

Abstract Reactivation of chronic Trypanosoma cruzi infection in solid organ transplant recipients (SOTRs) has been reported. The patient presented with a 2-week history of two painful erythematous, infiltrated plaques with central ulceration and necrotic crust on the left thigh. She had a history of chronic indeterminate Chagas disease (CD) and had received a kidney transplant before 2 months. Skin biopsies revealed lobular panniculitis with intracellular amastigote forms of T. cruzi. The patient was diagnosed with CD reactivation. Treatment with benznidazole significantly improved her condition. CD reactivation should be suspected in SOTRs living in endemic areas with clinical polymorphism of skin lesions.
