title: Venous varix on the dorsal aspect of the thumb: report of two cases.
abstract: Venous varix on the volar aspect of the digits or the hand is a rare subcutaneous lesion that is usually described as a firm, blue, and painful single nodule that contains thrombus. However, there have been no reports about venous varix on the dorsal aspect of the digits or the hand, so its features are unknown. We treated two patients who each had a soft blue painless mass on the dorsal aspect of the thumb that became enlarged with the tourniquet test. Ultrasonography and/or magnetic resonance imaging were used for assisting with the preoperative diagnosis, and showed each lesion was composed of two or more varicosities. Each mass was removed and was diagnosed as a venous varix without thrombus by histological examination.
