Sclerosing haemangioma of the lung. A case report.
A case of pulmonary sclerosing haemangioma composed of blood-filled cavernous spaces separated by septa containing sheets of uniform, epithelioid-type cells and numerous mast cells is described. Although the histogenesis has not been conclusively established, the appearances in this case favour a primary vascular lesion. The variable histological patterns observed in this tumour may cause problems in diagnosis; the differentiation from haemangioma, haemangiopericytoma, pulmonary chemodectoma and benign clear cell tumour of the lung is discussed.
