Lobules of endothelial-lined capillaries surrounding larger vessels. Other features (not shown here) are: a mixed inflammatory infiltrate may be present, the stroma may be edematous or fibrotic, and mitoses is common (1).
Also called "pyogenic granuloma" in some circles, but that term is really a misnomer because this entity is neither pyogenic (purulent) nor is it a granuloma or even granulomatous.
Usually affects boys < 15 year old. Presents with painless episodes of epistaxis. May see a red polypoid mass in the nasal cavity, which may be ulcerated.
Benign. Should not recur after complete excision.
