| Popis: | We ebcountered two cases of basaloid (-squamous) carcinoma of the esophagus. In Case 1, a 64-year-old man was operated on. The resected material showed an ulcerative and localized lesion measured 6.0×3.0cm and an erosive lesion at 0.5cm anal side from it. The histological diagnosis was basaloid (-squamous) carcinoma with moderately differentiated squamous cell carcinoma in a stage-grouping of a2, ly 2 (+), v 1 (+), n 4 (+), stage IV. Pleural effusion, ascites and multiple liver metastases were detected by ultrasonography and computed tomography four months after the surgery. He died of recurrence of esophageal cancer six months after the operation. At autopsy, systemic wide-spread recurrence of basaloid (-squamous) carcinoma was recognized. In Case 2, a 73-year-old man was operated on. The resected material revealed a 5.0×4.5cm protruding tumor and a 4.0×4.5cm protruding tumor and a 4.0×7.0cm ulcerative and infiltrated lesion. Histological diagnosis of the protruding tumor was basaloid (-squamous) carcinoma while that of the ulcerative and infil-trated tumor was moderately differentiated squamous cell carcinoma in a staging-grouping of al, ly3 (+), v1 (+), n3 (+), stage IV. He died of recurrence of esophageal cancer 15 months after the operation. Basaloid (-squamous) carcinoma of the esophagus is thought to have a high malignant potential. Therefore, more detailed studies of factors causing this high malignant potential are needed. Some bibliographical comments on 56 cases reported in Japan including our two cases are also presented to elucidate characteristic findings of the disease. |
