Venous aneurysm of the dorsal venous arch: a case with an unusual etiology.

Isolated venous aneurysms of the foot are rare. We report a case of venous aneurysm of the dorsal venous arch of the foot with an unusual traumatic etiology. This is a case report of a female patient with a gradually enlarging swelling on the dorsum of her foot located over the pressure area of her sandal straps. A clinical diagnosis of venous aneurysm was made, and she was treated with surgery. Most cases of superficial venous aneurysms only arouse medical interest, with few cosmetic complaints and no complications. This case is unique because it describes a traumatic venous aneurysm associated with repeated trauma caused by inappropriate footwear. All clinicians and allied health-care professionals involved in podiatric medicine should be aware of this clinical condition in the differential diagnosis of soft-tissue swellings in the feet.
