[Superficial and extensive epidermoid cancer of the esophagus].

A case of extensive squamous cell carcinoma of the esophagus in a 56 year old man, with an history of excessive alcoholic and tobacco consumption, is reported. After subtotal esophagectomy, the course was favorable 10 months after surgery. The pathological study of the surgical specimen showed that the tumor was superficial and confined to the mucosa and submucosa. The lesion measured 65 mm in length (after fixation) and was circumferential. Foci of moderate and severe dysplasia and inflammatory erosions were also observed. The relationship between extensive squamous cell carcinoma, dysplasia, esophagitis and the concept of "carcinogenic fields" are discussed. The necessity of large radical resection of the esophagus is emphasized.
