A 39-year-old man with a history of arteriovenous malformation in the upper right limb that was complicated with vascular-type ulcers and repeated soft tissue infection and who had needed a supracondylar amputation of the limb when he was 27 years old presented a new soft tissue infection that manifested with fever, chills, increase in the diameter of the stump with local skin erythema, and painful necrotic ulcers. The patient reported mild dyspnea for 3 months (World Health Organization functional class II/IV) that had worsened during the last week (World Health Organization functional class III/IV) with chest tightness and bilateral lower limb edema.
