title: Primary osseous malignant fibrous histiocytoma involving a rib.
abstract: A case is presented of an 86-year-old man who developed progressive chest wall pain over a 16-month period. Radiologic studies demonstrated lytic destruction of the right fourth rib anterolaterally. A limited thoracotomy led to the diagnosis of malignant fibrous histiocytoma. This represents an unusual primary bone lesion in the rib. A concise discussion of primary MFH of bone including its radiographic appearance, differential diagnosis, and pathology was presented.
