 Seventeen mucosal carcinoma and nineteen submucosal carcinoma of the esophagus were examined histopathologically, to evaluate the incidence of the permeation of vessels and lymph node metastasis according to the degree of invasion. Mucosal carcinomas were divided into three groups according to the degree of invasion (m2: 8 cases, m3: 9 cases). Submucosal carcinomas were divided into three groups according to the degree of submucosal invasion (sm1: 6 cases, sm2: 13 cases). Mucosal carcinoma did not show lymph node metastasis, but two of the mucosal carcinomas (m2: 1 case and m3: 1 case) revealed the permeation of vessels. Six submucosal carcinomas showed lymph node metastasis (sm1: 1 case, sm2: 5 cases). Carcinomas with deeper invasion had a statistically higher incidence of permeation of vessels (p<0.02), and a higher incidence of sprouting (p<0.005). Moreover, the incidence of sprouting was significantly correlated to the incidence of permeation of vessels (p<0.02), the incidence of high-grade cytological atypia of carcinoma cells (p<0.05) and the incidence of lymph node metastasis (p<0.005). When the superficial esophageal carcinoma showed both high-grade cytological atypia of carcinoma cells and sprouting, the likelihood of lymph node metastasis was 100% (6/6) and the specificity was 76.7% (23/30).

 In conclusion, esophagectomy with lymphadectomy or radiotherapy might be a suitable treatment for superficial esophageal carcinomas with high-grade cytological atypia of carcinoma cells and sprouting.
