Chronic ulceration following surgical excision of a Morton's neuroma due to an underlying arteriovenous malformation of the foot

摘要

An arteriovenous malformation (AVM) of the foot is a rarely encountered clinical pathology. Arteriovenous malformations are most commonly found in the brain and lungs, and when found in the lower limbs, are usually in the pelvis or thigh and not the foot or ankle. We describe a rare malformation that complicated surgical removal of a Morton’s neuroma, with chronic ulceration and failed wound healing. Successful treatment with conservative measures ensured full recovery. We believe all health care professionals should be aware of this pathology and consider it as a cause of delayed healing.
