Elastofibroma dorsi is a rare, benign, soft tumor located at the inferior pole of the scapula. We report a series of 8 patients (5 women, 3 men), with a mean age of 67 years (range, 44-80 years), and discuss the clinical presentation, diagnosis, and treatment. Six lesions were unilateral, and 2 were bilateral. All patients were referred from other clinics with a large, unknown tumor of the back. Two patients presented with symptoms of pain and clunking of the scapula on shoulder abduction. Five underwent simple excision of the tumor. Preoperative diagnosis by magnetic resonance imaging showed agreement with the histopathologic diagnosis. Three patients had the postoperative complication of hematoma formation. Presumptive diagnosis is possible by careful clinical examination and magnetic resonance imaging. Because postoperative hematoma is unexpectedly frequent and symptomatic, radical resection should be avoided, and only excisional biopsy is necessary for histopathologic diagnosis.
背部弹力纤维瘤是一种罕见的良性软组织肿瘤，位于肩胛骨下角。我们报告了一组8例患者（5名女性，3名男性），平均年龄67岁（范围44 - 80岁），并讨论了临床表现、诊断和治疗。6个病变为单侧，2个为双侧。所有患者均从其他诊所转诊而来，背部有一个大的、不明性质的肿瘤。2例患者出现肩部外展时肩胛骨疼痛和弹响症状。5例患者接受了肿瘤单纯切除术。术前磁共振成像诊断与组织病理学诊断相符。3例患者术后出现血肿形成并发症。通过仔细的临床检查和磁共振成像可进行初步诊断。由于术后血肿意外频发且有症状，应避免根治性切除，仅进行切除活检以获得组织病理学诊断。
