Elastofibromatous lesion of the stomach in a patient with elastofibroma dorsi

Abstract

A 69-year-old woman underwent partial gastrectomy because of peptic ulcer which resisted medical treatment. The resected stomach exhibited a wide thickening of the antral wall around a 1.2 X 0.8 cm ulcer. The cut surface showed a gray-white thickened submucosal layer and had a rubbery elastic consistency. Microscopically, the thickened areas consisted of abundant acellular collagen fibers containing numerous elastinophilic, thick, serrated fibers and globules, identical with the elastofibroma fibers seen in elastofibroma dorsi. Reexamination of the patient revealed bilateral subscapular masses; one of these was biopsied and proved to be an elastofibroma dorsi.
