title: Periungual and subungual arteriovenous tumours.
abstract: We describe the clinicopathological findings in five cases of an acquired vascular tumour involving periungual or subungual tissue. We believe that these represent acral arteriovenous tumours (cirsoid aneurysms). There are no previous reports of subungual or periungual acral arteriovenous tumours.
