Abstract Although New World cutaneous leishmaniasis is not itself a life-threatening disease, its treatment with systemic antimonials can cause toxicity that can be dangerous to some patients. Intralesional meglumine antimoniate provides a viable, less toxic alternative. Herein, we describe an alternative treatment with subcutaneous intralesional injections of meglumine antimoniate into large periarticular lesions of three patients with cutaneous leishmaniasis and comorbidities. This treatment was safe, successful, and well tolerated. This case series suggests that intralesional meglumine antimoniate is an effective therapy for cutaneous leishmaniasis, even with periarticular lesions. This hypothesis should be tested in controlled clinical trials.

A terapêutica com drogas antitireoidianas pode ser acompanhada de efeitos colaterais. Apresentamos um caso de paciente com diagnóstico de Doença de Graves que na vigência da terapêutica com metimazol desenvolveu um quadro extenso de vasculite de membros inferiores. A partir da suspensão do metimazol e da introdução de prednisona em doses imunossupressoras as lesões cutâneas entraram em involução.

Treatment with antithyroid drugs may be accompanied by side effects. We present a patient diagnosed with Grave's Disease who developed extensive vasculitis in the lower limbs during methimazole use. After suspension of the methimazole and the introduction of prednisone in immunesupressor doses the cutaneous lesions started to involute.
