A series of 29 pulmonary sclerosing haemangiomas is analysed. Included is one case with multiple tumours and another with metastatic growth in a hilar lymph node. Histochemical and electron microscopic studies show that type 2 pneumocytes are an important constituent cell type though bronchial structures, tumorlets and angiomas also occur within these tumours. They are considered to be pulmonary hamartomas formed from distal lung structures. They are of slow growth and have been confused in the past with pulmonary histiocytomas and plasma cell granulomas.
