elastocollagenous ball

A structure seen in skin biopsies of patients with nephrogenic systemic fibrosis (NSF) and currently thought to be unique to NSF, which consists of refractile elastic fibres surrounded by coarse collagen. It may provide a nidus for osseous metaplasia that develops over time and is thought to represent an involuting stage of NSF.
