ABSTRACT
Renal cell carcinoma involves the inferior vena cava (IVC) in approximately 5-10% of the patients. Presently surgical extirpation is the only form of therapy that can result in cure. Circulatory arrest with cardiopulmonary bypass is an operative technique that recently has been used to assist in resection of tumors that extend into the vena cava above the level of hepatic veins. We performed removal of tumor thrombi of IVC in 4 patients. All of them who had the renal cell carcinormas with infrahepatic vena caval extension were performed by standard surgical technique without cardiopulmonary bypass. But in one patient, inferior vena caval thrombectomy was done using circulatory arrest because of the recurred extension of the tumor thrombi within the vena cava above the insertion of the hepatic vein. All patients were recovered without any significant problems.

Though leiomyomas are the commonest benign tumors in the esohpagus, the vast majority of the leiomyomas of alimentary tract occurs outside the esophagus. Leiomyoma is mostly solitary, and multiple lesions are rare. Diffuse esophageal leiomyomatosis is a very rare disease, which is the condition having diffuse thickening of esophageal musculature and with or without discrete lesion. We are reporting a typical case of diffuse leiomyomatosis of the esophagus in a 37-year-old woman successfully resected.
