Abstract:
A case of metastatic chondrosarcoma of the stomach in a 34-year-old female is reported. This patient had been diagnosed as having chondrosarcoma of the right knee and was operated on in 1984. Thereafter, there was repeated local recurrence and operations were performed on multiple metastases, including those of the lung, brain, ovary and spleen. In September, 1990, the patient was readmitted because of advanced anemia. Gastroendoscopy disclosed a firm elevated lesion with central irregular erosion. Histologically, there was cellular atypical cartilage with pleomorphic chondrocytes, which showed the same staining reactions as those in the primary lesion. Therefore this case was diagnosed as metastatic chondrosarcoma. This may be the first documentation of a case of gastric metastasis of chondrosarcoma.
