Description

We have tried to classify macroscopically 54 superficial esophageal carcinomas whose infiltration is limited within submucosa (sm) and to discuss the relation between macroscopic types and histologic ones.<BR>Some of polypoid type, tumorous type and superficial elevated type belong to specific type different from squamous cell carcinoma. Their histology shows undifferentiated carcinoma, carcinosarcoma or adenoid cystic carcinoma.<BR>Based on lymph node metastasis and vascular invasion, we have also studied “degree of malignancy” in the superficial carcinoma.<BR>The prognosis of early carcinoma, especially carcinoma in situ, superficial flat type and differentiated squamous cell carcinoma is rather good.<BR>The histology of tumorous type, superficial depressed type and superficial mixed type is usually poorly differentiated squamous cell carcinoma, undifferentiated carcinoma or carcinosarcoma, so the prognosis of these types is very poor.<BR>Superficial esophageal carcinoma has usually distant lymph node metastasis without local one.
