title: A rare case of malignant diaphragmatic hemangiopericytoma in a patient with pleural effusion.
abstract: This paper reports a case of primary malignant diaphragmatic hemangiopericytoma in a 30-year-old male patient operated on for a diaphragmatic mass. The tumour was discovered on a TC scanning performed to explain the etiology of an exudative pleural effusion in a patient admitted for dyspnea, fever and thoracic pain. Given the rarity of this disease, the histological and pathological features of hemangiopericytoma are discussed in the light of the new classification system for soft tissue and bone tumours, as well as its currently accepted therapeutical guidelines.
