Congenital esophageal stenosis due to tracheobronchial remnants is one of main forms of congenital esophageal stenosis, and it was first described by Frey and Duschel in l936. An 18-month-old male presented with underdevelopment and dehydration state due to persistent vomiting several times per day since 3 months after his birth. Esophagogram revealed an elongated and diiated esophagus with marked stenosis at distal portion. Partial distal esophagectomy was performed. Histologically, the thickened esophageal wall is composed of tracheobronchial remnants including hyaline cartilages, mucous glands, and ductal structures lined by ciliated respiratory epithelium under stratified squamous mucosa.
