The histopathological typing of 48 cases of ESO-phageal adenocarcinoma and its tissue origin

Of 2487 cases of esophageal carcinoma pathologically confirmed after resection in 1978–1988 in Shantou, adenocarcinoma accounted for 1.93% (48 cases). These were divided into 6 types; Ordinary well - differentiated adenocarcinoma, 10 cases; Ordinary poorly - differentiated adenocarcinoma, 11 cases; Adeno - squamous carcinoma, 18 cases; Muco - epidermoid carcinoma, 4 cases; “Basal Cell - Like Carcinoma”, 4 cases; Cylindroma - Like carcinoma, 1 case. Mucohistochemistry and immuno-histochemistry studies revealed some differences among these types; And their prognosis also varied. The tissue origin of these tumors were discussed.
