Abstract：
Pulmonary hamartoma is the most commonly resected benign neoplasm of lung. The mesenchymal cystic subtype is a rare and often bilaterally occurring variant composed of multiple cysts and nodules. Herein, we present an asymptomatic 70-year-old woman with a large and mostly cystic growth of right hilar region. Computed tomography of the chest and fluorodeoxyglucose positron emission tomography/computed tomography imaging traced its origins to right middle lobe. Overall features suggested primary lung cancer or perhaps other cystic lung disease.Because transbronchial lung biopsy failed to establish a histologic diagnosis, right middle lobectomy was undertaken by video-assisted thoracoscopic surgery. The gross surgical specimen harbored a single and sizeable (8.0 × 4.0 cm) cystic lesion containing multiple yellow-white nodules. A diagnosis of mesenchymal cystic and chondroid hamartoma was ultimately rendered. This particular case is noteworthy, given the initial clinical resemblance to primary lung cancer.
摘要：
肺错构瘤是最常见的切除的肺良性肿瘤。间充质囊性亚型是由多个囊肿和结节组成的罕见且经常双侧发生的变体。在这里，我们介绍了一名无症状的70岁女性，其右肺门区域有一个大的，主要是囊性的生长。胸部计算机断层扫描和氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描成像将其起源追溯到右中叶。总体特征提示原发性肺癌或其他囊性肺病。因为经支气管肺活检未能建立组织学诊断，右中叶切除术采用胸腔镜手术.大体手术标本有一个单个且相当大（8.0×4.0cm）的囊性病变，其中包含多个黄白色结节。最终诊断为间叶囊性和软骨样错构瘤。这个特殊的案例值得注意，考虑到最初与原发性肺癌的临床相似。
