David Cassarino, MD, PhD

Low-magnification view of a hobnail hemangioma demonstrates superficial dilated vascular spaces image in the papillary dermis with deeper small blood vessels and stromal hemosiderin deposits image.

Higher power examination shows a hobnail hemangioma with superficial dilated vessels lined by small endothelial cells protruding into the lumina image and showing nuclear hyperchromasia.
