We herein report a case of pulmonary hyalinizing granuloma (PHG), which is a rare pulmonary mass. A 69-year-old man with no symptoms presented to our hospital because of the appearance of an abnormal shadow on chest X-ray. Computed tomography revealed a right middle-lobe mass with spicula and infiltration into the upper lobe. Since a bronchofiberscopic examination showed no malignant cells in the specimen, the patient underwent thoracoscopic surgery, which revealed PHG. Spiculation and interlobar infiltration, which comprise the characteristic features of primary lung cancer, are uncommon presentations of this rare entity.
我们在此报告一例肺透明变性肉芽肿（PHG），这是一种罕见的肺部肿块。一名69岁无症状男性因胸部X线出现异常阴影前来我院就诊。计算机断层扫描显示右中叶肿块伴有毛刺征并侵及上叶。由于支气管纤维镜检查标本中未发现恶性细胞，该患者接受了胸腔镜手术，结果显示为PHG。毛刺征和叶间浸润是原发性肺癌的特征性表现，在这种罕见疾病中并不常见。
