Superficial carcinoma of the esophagus.
Nine cases of superficial carcinoma of the esophagus were described. Although 3 patients complained of abdominal sensations on swallowing or dysphasia, 6 patients did not present with any symptoms related to the esophageal lesion. The radiologic diagnosis is particularly difficult in cases with superficial type esophageal cancer, and no definitive findings were obtained in three such cases. However, esophagoscopy using Lugol spray was far more effective for the recognition of these superficial lesions. Although surgical resection of the esophagus is technically easier in these cases, the indications of surgery should be carefully evaluated. One operative death occurred in our series. In cases that are good indications, however, wide lymph node dissection should be carried out, since metastases occur even to distant lymph nodes, particularly in cases with cancer invasion of the submucosal layer. The histopathologic diagnosis was squamous cell carcinoma in 8 cases, but in one case it was adenocarcinoma of mucus-secreting gland origin in the mid-thoracic esophagus.
