The diagnostic cytomorphologic findings in a case of elastofibroma dorsi are described in this report. The correct diagnosis was initially overlooked 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 fibroblasts, adipose tissue, and swollen lightly staining cyanophilic elastic fibers in a background of collagenous matrix. Cross sections of the elastic fibers had the typical serrated and globular appearance. These fibers stained positive with elastin stains. The cytomorphology of elastofibroma dorsi with diagnostic pitfalls and differential diagnostic dilemmas are discussed in this article.
本报告描述了一例背部弹力纤维瘤的诊断性细胞形态学发现。细针穿刺时最初漏诊，随后经手术活检确诊。然而，对细针穿刺标本复查发现有少量但具有诊断意义的材料。细胞学检查显示在胶原基质背景中存在成纤维细胞、脂肪组织和肿胀的淡染嗜蓝弹力纤维。弹力纤维横断面呈典型的锯齿状和球状外观。这些纤维用弹性蛋白染色呈阳性。本文讨论了背部弹力纤维瘤的细胞形态学、诊断陷阱及鉴别诊断难题。
