title: [Rare localizations of digestive adenocarcinoma in children. Apropos of 2 cases].
abstract: The authors report two cases of adenocarcinoma of the digestive system in children both of which were located in unusual sites. A child of 9 years old had an adenocarcinoma of the small bowel and a boy of 16 years who was known to have a long-standing hiatus hernia developed an adenocarcinoma of the oesophagus. In children these tumors have some characteristic features. They develop on a preexisting lesion. Evolution is rapid. From the pathological point of view, anaplasic and colloide patterns are frequent.
