We present a case of sarcoidosis presenting as unilateral forearm swelling. A 65-year-old male with a long history of asthma presented with unexplained left forearm and hand swelling. Over many years, chest imaging had been devoid of adenopathy or parenchymal findings suspicious for sarcoid, until after the extremity findings emerged. The patient was diagnosed based on subcutaneous, dermal and mediastinal lymph node histopathology. Sarcoid presenting with isolated extremity findings prior to more typical pulmonary manifestations is rare even for cutaneous or soft tissue sarcoid, highlighting the need to maintain a high index of suspicion for sarcoidosis.
我们报告一例以单侧前臂肿胀为表现的结节病病例。一名有长期哮喘病史的65岁男性出现不明原因的左前臂和手部肿胀。多年来，胸部影像学检查未发现淋巴结肿大或提示结节病的实质病变，直到出现肢体病变后才发现。该患者根据皮下、真皮和纵隔淋巴结组织病理学检查确诊。结节病在出现更典型的肺部表现之前先出现孤立的肢体病变，即使对于皮肤或软组织结节病来说也很罕见，这凸显了对结节病保持高度怀疑指数的必要性。
