title: Fibers in idiopathic retroperitoneal fibrosis: a case report.
abstract: A case of idiopathic retroperitoneal fibrosis in a 33-yr-old female is reported. Many fiber-like crystals were noted within macrophages and the interstitial tissue of the lesion. The crystals appeared tan in hematoxylin- and eosin-stained slides and were birefringent under polarized light. The identity of the crystals was not established.
