Giant arteriovenous hemangioma (cirsoid aneurysm) of the nose.

We describe a 97-year-old woman who presented to our clinic with an unusually large pendulous asymptomatic soft tumor on the left side of her nose. History revealed a 40-year course, with accelerated growth in the last 9 years. Histology of this 7 x 3-cm large tumor revealed vascular structures composed of densely aggregated thick- and thin-walled vessels, separated by fibrous tissue. These features are characteristic for an arteriovenous hemangioma, also called cirsoid aneurysm. The distal part of the tumor showed nearly total fibrosis and at the proximal end of the tumor signs of incipient basal cell carcinoma were observed. In spite of the accelerated growth, unusual size, and the presence of a basal cell carcinoma at the base of this tumor, giant cirsoid aneurysms appear to be of a benign nature and thus conservative, nonradical surgical treatment can be performed. The tumor was removed by argon laser surgery with excellent results and no sign of recurrence after 1 year.
