ABSTRACT
A case of primary chondrosarcoma of the left lung in 50 year-old man is presented. The tumor was diagnosed as primary chondrosarcoma of the lung after exclusion of any primary lesion elsewhere. Histologically, tumor consisted of predominantly chondromatous lesion. Immunohistochemistry showed that tumor cells positive for S-100 protein and vimentin, and negative for epithelial markers. On the basis of clinical, histological and immunohistochemical studies, the tumor was diagnosed as a primary chondrosarcoma of the lung.

Adult granulosa cell tumor (GCT) of the ovary is the most common malignancy amongst the sex cord stromal tumors. Clinical stage, age, tumor size, residual disease and several histologic factors have been reported to be of prognostic significance. There were 839 ovarian malignancies at our institute during the period from 1998 to 2002. Out of 54 granulosa cell tumors, 40 cases were evaluable which includes 37 cases of adult GCT and 3 cases of juvenile GCT. They were studied retrospectively. Majority of patients presented with abdominal symptoms and FIGO stage I. All patients were treated surgically and 62.1% of adult GCTs were given post-operative chemotherapy. Clinical stage, presence of residual disease and tumor volume were the most important prognostic factors. Age of patient, menstrual status, post-operative chemotherapy, mitosis or histological patterns were of little significance in our study.
