肺错构瘤是最常见的肺内良性肿瘤。大部分在肺实质,少数在支气管内。临床上应与恶性肿瘤相鉴别。另外,生长在支气管内的错构瘤易引起阻塞性肺炎、肺不张和肺脓肿等继发疾患。我院自1965年5月至1981年11月,共收治肺错构瘤19例,另在尸检中发现2例。本文就21例的经验,结合文献进行讨论。 Pulmonary hamartoma is the most common benign lung tumor. Most are in the lung parenchyma, and a few are in the bronchus. Clinically, it should be differentiated from malignant tumors. In addition, hamartomas that grow in the bronchi can easily cause secondary diseases such as obstructive pneumonia, atelectasis, and lung abscesses. In our hospital from May 1965 to November 1981, 19 cases of pulmonary hamartoma were treated and another 2 cases were found during autopsy. This article discusses the experience of 21 cases combined with literature.
