Palmar Digital Vein Thrombosis / 대한피부과학회지

ABSTRACT

Palmar digital vein thrombosis causing one or more nodules seems to be a relatively rare condition. Only 20 cases of palmar digital vein thrombosis have been reported worldwide in the English language literature. It presents with a painful, firm and blue nodule located at or in close proximity to one of the flexion creases. The etiology remains unknown, but changes in the vessel wall related to the anatomic characteristics of the palmar digital veins may play a role, along with intraluminal stasis. Two patients with blue nodule located in close proximity to flexion creases on the volar side of the finger presented to our hospital. Histological examination showed organizing thrombus within the dilated vessel. We report here on these two cases of palmar digital vein thrombosis.
