An Unusual Cause of Haemoptysis in an Adolescent: Bronchial Mucoepidermoid Carcinoma
一名青少年不尋常的咯血原因:支氣管黏液表皮樣癌

Abstract

Tracheo-bronchial mucoepidermoid carcinoma (MEC) is a rare tumour. So far, less than 80 cases were reported in paediatric population, with none reported in Hong Kong. Although it has a predilection for large airways, it lacks a specificity of clinical symptoms and signs. Computed tomography is the ideal radiological imaging modality to detect such endobronchial lesion, and the diagnosis is usually established with bronchoscopy. The majority of paediatric MEC tumours are low-grade and easily amenable to conservative resection. In this case report, a 14-year-old adolescent who had been treated as recurrent pneumonia, presented to our unit with non-remitting cough and haemoptysis. Subsequent work-up diagnosed low grade MEC of left lower lobe bronchus. With the knowledge of MEC being a potential disease entity, it should alert the paediatrician to consider further work-up especially in the context of respiratory symptoms that fail to respond to the usual medical therapy.

氣管─支氣管黏液表皮樣癌(MEC)是一種罕見的腫瘤。到目前為止,少於80名兒童病例曾被報導,而在香港則尚未有報導。雖然它多發生在大氣道,但缺乏特異性的臨床症狀和體徵。電腦斷層掃描是理想的放射學方法檢測這種支氣管內病變,診斷通常由支氣管鏡檢查確定。多數兒童MEC是低惡性度腫瘤,可行保守式手術切除。在這種病例報告中,一名14歲的青少年被當作反复肺炎治療,在我院表現為不能緩解的咳嗽及咯血。隨後的檢查診斷左肺下葉支氣管低惡性黏液表皮樣癌。兒科醫生應認識到MEC是潛在的疾病,並應該特別注意當病童出現上述呼吸道症狀,而常規藥物治療無效時,應考慮作進一步的檢查。
