Abstract:
Arteriovenous malformation (AVM) consists of an abnormal connection between artery and vein without any interposed capillary bed, and is usually congenital. However, acquired AVM is quite rare, and is usually caused by injury, which induces direct arteriovenous shunting. Acquired digital AVM is a distinct entity, which was first described by Kadono et al. in 2000, and was thought to result from shunts between an artery and a vein in a finger tip. We report a case of acquired digital AVM in a 44-year-old women. The patient showed punctate hyperketatotic ectasia on the pulp of the right thumb. Histological finding showed dilated venous and arterial vessels in upper and lower dermis, and shunts between arteriols and venules.
