A 59-year-old woman was found to have an abnormal shadow on chest X-ray film during a general medical examination. A nodule with homogenous density and clear margin was seen in the lingular segment of the left lung. Since this shadow gradually enlarged during a 1.8 year follow up period, she was admitted to our hospital. A wedge resection was carried out by video-assisted thoracotomy. The resected tumor was histologically diagnosed as a benign clear cell tumor of the lung. Immunohistochemically, the tumor cells showed strong anti-melanoma monoclonal antibody (HMB-45) expression. This disease is extremely rare and only 31 cases including the present case have been reported in Japan.
一名59岁女性在普通体检时胸部X光片发现异常阴影。左肺舌段可见一个密度均匀、边界清晰的结节。由于该阴影在1.8年的随访期间逐渐增大，她被收治入院。通过电视辅助胸腔镜进行了楔形切除术。切除的肿瘤经组织学诊断为肺良性透明细胞瘤。免疫组织化学检查显示，肿瘤细胞强烈表达抗黑色素瘤单克隆抗体（HMB - 45）。该病极为罕见，日本包括本病例在内仅报道了31例。
