ESOPHAGEAL ABNORMALITIES DEVELOPED FROM T RACHEOBRONCHIAL REMNANTS - 2 REPORTS WITH DELAYED DIAGNOSIS IN ADULT

Congenital esophageal stenosis and bronchogenic cyst are secondary to the same dysembryoplastic disorder in spite of different clinical sign s. These lesions are revealed during infancy, unusually during adult a ge. Dysphagia is the most common symptom. Our two cases highlight thes e topics. Imaging methods displayed, in case 1, a distal stenosis, ass ociated with a proximal dilatation, in case 2, a benign independent ma ss, without connection with the respiratory tract. A chirurgical excis ion was carried out in the two cases and the post operative course was uncomplicated. Histologically the two resection specimens showed a re spiratory mucosa trapping cartilaginous pieces.
