An atypical case of deep vascular hamartomata

A 17-year-old man who initially had an injury to the lower extremity was eventually diagnosed as an unusual case of deep vascular hamartomata. After initial treatment, the patient returned on numerous occasions with pain, swelling, and a cystic lesion of the leg. Despite operative excision of the lesion, which spread to the abdomen, it continually reappeared. Surgeons should be aware of hamartomata in patients with a warm, painful, swollen lower extremity.
