ELASTOFIBROMA DORSI - DIAGNOSTIC PROBLEMS AND PITFALLS

The diagnostic cytomorphologic findings in a case of elastofibroma dor si are described in this report. The correct diagnosis was initially o verlooked on fine-needle aspiration, and was subsequently made by open biopsy. Review of the FNA material, however, demonstrated scanty but diagnostic material Cytologic examination revealed a mixture of fibrob lasts adipose tissue, and swollen lightly staining cyanophilic elastic fibers in a background of collagenous matrix. Cross sections of the e lastic fibers had the typical serrated and globular appearance. These fibers stained positive with elastin stains. The cytomorphology of ela stofibroma dorsi with diagnostic pitfalls and differential diagnostic dilemmas are discussed in this article. (C) 1994 Wiley-Liss, inc.
