肺炎性假瘤是指在肺实质内,由非特异性炎症所引起的一种瘤样增生性病变。临床诊断较困难,常以肺癌或其它肺部肿块而手术切除。镜下组织结构复杂,在病理医生经验不足时,亦易误诊为某些真性肿瘤。现将所见的15例,报告如下。 Pneumonic pseudotumor is a neoplastic hyperplasia caused by nonspecific inflammation in the lung parenchyma. Clinical diagnosis is more difficult and surgical resection is often performed with lung cancer or other lung masses. The microscopic structure is complex, and when pathologists lack experience, they are also misdiagnosed as certain true tumors. The 15 cases we have seen so far are reported below.
