Abstract
|
|
|
|
Acquired digital arteriovenous malformation (ADAVM) consists of an abnormal connection between the arteriole and venule in the acral area of extremities, particularly the fingers. Clinically, the lesions appear as small, slightly- elevated, dark brown erythematous macules on the distal part of fingers. The histological specimens shows close approximation between thin-walled venule and thick-walled arteriole and possibly a direct arteriovenous shunt adjacent to each other lying in the dermis. We herein report seven stereotypical cases of ADAVM.
