错构瘤是肺部常见的良性肿瘤,发生在纵隔者极少见。本文介绍我院经手术切除和病理证实的2例纵隔错构瘤,并结合文献对病理类型略作讨论。 1 病例报告 例1,男性,40岁。右肩背部不适2年,于1984年4月住院。查体及实验室检查未见异常,胸部X线显示右上纵隔肿物阴影,椭圆形,密度均匀,边缘光滑,10cm×6cm×4cm。术前诊断:右上纵隔神经源性肿瘤。于1984年4月11日在全麻下行右侧开胸探查术,术中发现肿瘤位于后纵隔壁层胸膜下,切开胸膜见肿瘤为两个,脊柱旁肿瘤6cm×4cm×2cm。胸膜顶侧肿瘤6cm×5cm×5cm,两肿瘤相贴,肿瘤包膜面血管丰富,为来自肋间动脉和锁骨下动脉的分支,分离时极易出血,行肿瘤摘除术。肿瘤标本:大体观察,外观呈棕红色,有完整包膜,切面呈鱼肉状。病理报告:血管淋巴样错构瘤。随访10年无复发。
Hamartomas are common benign tumors of the lung and rare in the mediastinum. This article describes two cases of mediastinal hamartoma confirmed by surgical resection and pathology in our hospital, and a brief discussion of the pathological type in combination with the literature. 1 Case report Example 1, male, 40 years old. Right shoulder and back discomfort for 2 years, hospitalized in April 1984. Physical examination and laboratory examination showed no abnormalities. The chest X-ray showed shadows of the right upper mediastinal mass, oval shape, uniform density, and smooth edges, 10 cm x 6 cm x 4 cm. Preoperative diagnosis: right upper mediastinal neurogenic tumor. On April 11, 1984, he underwent right thoracotomy under general anesthesia. During the operation, he found that the tumor was located in the posterior mediastinal pleura, and the pleura was seen with two tumors. The paraspinal tumor was 6cm x 4cm x 2cm. The top pleural tumor was 6cm × 5cm × 5cm. The two tumors were affixed. The tumor envelope surface was rich in blood vessels. It was a branch from the intercostal artery and subclavian artery. It was easily bleed during separation and tumor removal was performed. Tumor specimens: General observation, the appearance of brown-red, with a complete envelope, cut surface was fish-like. Pathology report: Angiolymphoid hamartoma. Follow-up for 10 years without recurrence.
