Pulmonary sclerosing hemangioma (SH) is an uncommon benign or low-grade malignant tumor. Multicentric SH and SH with lymph node metastasis have rarely been reported. The present report describes a case of pulmonary SH with lymph node metastasis in a middle-aged female. A nodule was found incidentally in the lower left lung. The patient underwent left lower pulmonary lobectomy and lymph node dissection. Histologically, the nodule demonstrated the characteristic features of SH and one of the resected lymph nodes contained a metastasis of this tumor. Thus, pulmonary SH has the potential to metastasize, a potential not suggested by histological features.
肺硬化性血管瘤（SH）是一种罕见的良性或低度恶性肿瘤。多中心性SH及伴有淋巴结转移的SH鲜有报道。本报告描述了一例中年女性肺SH伴淋巴结转移的病例。在左肺下叶偶然发现一个结节。患者接受了左下肺叶切除术及淋巴结清扫术。组织学检查显示，该结节具有SH的特征性表现，且切除的一个淋巴结中存在此肿瘤的转移灶。因此，肺SH有发生转移的可能，而组织学特征并未提示这种可能性。
