Malignant haemangiopericytoma of the chest wall.

A patient with malignant haemangiopericytoma of the right second rib is described. En-bloc resection of this rare tumour with the adjacent upper lobe of the lung and part of the chest wall could be achieved. The clinical and morphologic features of this case are presented. On account of the high risk of local recurrence and distant metastasis, we think an adjuvant chemo- and radiotherapy is indicated.
