We present a case of a 70-year-old woman with extensive, multiple, dystrophic, necrotic, and bleeding ulcers on her forearm stump, shoulder, and chest wall. She had previously undergone a mid-forearm amputation due to a bleeding fungating ulcer from an arteriovenous malformation (AVM) on the dorsum of her right hand. Considering her history, AVM was suspected as the cause of the lesions. Due to significant renal impairment, duplex ultrasound (DU) was crucial in diagnosing and subsequent surgical management of her multifocal AVMs.
