We present a 60-year-old man with biopsy-proven metastatic squamous cell carcinoma of the right inguinal and external iliac lymph nodes with unknown primary. Hypermetabolic soft tissue masses were identified in bilateral subscapular regions on follow-up positron emission tomography (PET)-computed tomography (CT) after completion of chemoradiation. The right subscapular mass was biopsied under CT guidance, and histopathology showed it to be elastofibroma dorsi. Elastofibroma dorsi is a benign tumor with no malignant potential; due to its ill-defined appearance and tracer uptake on PET-CT, it can be misdiagnosed as soft tissue sarcoma. This report describes the typical location and imaging features of this incidental hypermetabolic mass.
我们报告一例60岁男性，经活检证实为右侧腹股沟和髂外淋巴结转移性鳞状细胞癌，原发灶不明。在放化疗完成后的随访正电子发射断层扫描（PET）-计算机断层扫描（CT）中，双侧肩胛下区域发现代谢增高的软组织肿块。在CT引导下对右侧肩胛下肿块进行活检，组织病理学显示为背侧弹力纤维瘤。背侧弹力纤维瘤是一种无恶性潜能的良性肿瘤；由于其边界不清的外观以及在PET-CT上有示踪剂摄取，它可能被误诊为软组织肉瘤。本报告描述了这个偶然发现的代谢增高肿块的典型位置和影像学特征。
