title: Fibrosarcoma of the thymic region. A case report.
abstract: Fibrosarcoma of the mediastinum is an unusual tumor and only few cases have been reported. We describe the clinical and pathologic findings of a case of mediastinal mass in a 34 year old woman. The histologic, histochemical, immunocytochemical and ultrastructural features of the tumor were consistent with a diagnosis of fibrosarcoma. Furthermore, the tumor displayed evidence of close relations with the thymus capsule; the possibility that it may arise from the thymic stroma is considered. The differential diagnosis of spindle cell tumors of the mediastinum is also discussed.
