기관지원성 낭종 - 한 기관에서의 10년간의 경험 = Bronchoginic Cyst Experience of One Hospital for Ten Years

다국어 초록 (Multilingual Abstract)

Background : Bronchogenic cyst is rare malformation of primitive foregut. It is usually located in lung and mediastinum, but rarely presented in unusual locations, such as diaphragm, abdomen, retroperitoneum, esophagus, neck, soft tissue and skin. Their histologic finding shows cystic mass lined by ciliated columnar epithelium and supporting fibrous tissue containing glands, hyaline cartilage, smooth muscle, nerve bundle or alveolar units.
Methods : We have reviewed medical records and corresponding slides of last ten years about each histologic component; cartilage, submucosal gland, smooth muscle, nerve bundle, alveolar units and epithelial metaplasia, particularly.
Results : Ten cases of bronchogenic cyst is collected for ten years. The distribution of age is wide from 2 to 80 years old, and mean age is 42.4 years old, median age is 43 years old. The ratio of male relation to female is 2:8. They are presented in lung (2 cases) and mediastinum (5 cases), in addition anteior neck (1 case), hypopharynx (1 case) and retroperitoneum (1 case). All bronchogenic cyst are lined by pseudostratified ciliated columnar epithelium. There are focal squamous immature metaplasia (30%), hyaline cartilage (30%), submucosal glands (70%), smooth muscle (70%), nerve bundle (40%) and alveolar units (10%).
Conclusion : Bronchogenic cyst is rare malformation. Pathologic diagnosis is made with some distinctive component seen in normal bronchus. But some case should be differentiated from cystic mass with pseudostratified ciliated columnar epithelium. So we search helpful findings for differential diagnosis.
