Angiokeratoma circumscriptum. This vascular ectasia may be present at birth, although it has been reported to develop in childhood and even adulthood. There is a higher incidence in females. Lesions are most commonly found on the lower extremities, but may be found elsewhere. Lesions consist of small nodules or larger plaques characterized by a dark red to purple color and a warty, hyperkeratotic scale sometimes in a linear distribution. These lesions may bleed when traumatized.
