A 3-year-old girl was evaluated for persistent middle lobe atelectasis. Fiberoptic bronchoscopy revealed a spherical mass occupying the middle-lobe bronchus. The biopsy specimen disclosed a low-grade mucoepidermoid carcinoma. A lobectomy was performed. The patient is in good condition 2 years after the operation. Mucoepidermoid tumors are rare bronchial adenomas comprising 1% of all lung neoplasms. Children are very infrequently affected. The clinical behavior of these tumors is controversial. Surgical resection of the low-grade-type tumor has an excellent prognosis.
一名3岁女孩因持续性中叶肺不张接受评估。纤维支气管镜检查发现一个球形肿块占据中叶支气管。活检标本显示为低级别黏液表皮样癌。进行了肺叶切除术。术后2年患者状况良好。黏液表皮样肿瘤是罕见的支气管腺瘤,占所有肺肿瘤的1%。儿童很少受到影响。这些肿瘤的临床行为存在争议。低级别类型肿瘤的手术切除预后良好。
