Histopathologic examination of the papule revealed a relatively well-circumscribed vascular proliferation consisting of dilated and angulated vascular channels lined by a single layer of widely spaced inconspicuous endothelial cells with only mild cytologic atypia. Focal branching of the vascular channels and projections of endothelium-covered stroma into the vascular lumina were seen. There was a mild associated chronic inflammatory infiltrate. The lesion was limited to the superficial to midreticular dermis and did not infiltrate the deep dermis or subcutaneous tissue.
