Staghorn pattern of vascularity

Last revised by Frank Gaillard on 21 Nov 2021

The staghorn pattern of vascularity is a pathological term describing a pattern of vascularity seen on low-power light microscopy. It is defined by multiple thin-walled, sharply-branched and jagged vessels having an "antler-like" or "staghorn-like" appearance 1.

It is classically described with solitary fibrous tumors, but it is a non-specific finding seen in a number of tumors (e.g. some sarcomas).
