Procedures
A skin biopsy (shave or punch) allows histologic confirmation of the diagnosis.

Histologic Findings
On scanning magnification, a sharply circumscribed vascular proliferation usually is noted, often embraced in part by a collarette of epithelium and adnexal structures. Higher magnification demonstrates numerous venules in a thickened papillary dermis. Older lesions often display prominent collagen bundles, which is an appearance suggesting septa.

A large polypoid angioma, deeply red to violaceous cherry, appears in the center of the field. Surrounding the angioma are several small bright red macules and papules that represent cherry hemangiomas in the earlier stages of evolution.
