Thrombosed vascular malformation within the flexor tendon sheath of the index finger in the palm

摘要

Vascular malformations are relatively infrequent among benign lesions of the hand. We report the case of an arteriovenous malformation in a 48-year-old white woman presenting a mass in her left hand without any symptoms. The diagnosis was confirmed by histopathology and the lesion completely removed by surgery.
