ABSTRACT
Solitary fibrous tumors are rare mesenchymal tumors accounting for <5% of all neoplasms in the pleura and other sites. A 45-year-old man reported to us with cough and dyspnea. Radiological investigations revealed a giant mass displacing the mediastinum to the left. The tumor weighing 3.0 kg was successfully resected via a right thoracotomy. Histology and immunohistochemistry confirmed a benign tumor. Recurrence and malignant transformation of these benign tumors have been reported. Our patient has been followed up for 4 years with no recurrence.

Primary osteosarcoma arising from the ribs is very rare. An unusual case of a primary chondroblastic osteosarcoma of the rib in a 30-year-old woman is described here. The patient underwent wide excision of the tumor along with the involved rib, followed by chemotherapy. Although clinically unsuspected in this unusual site, pathology confirmed a completely resected chondroblastic osteosarcoma.
