Primary cardiac haemangiomas. A report of 2 cases.

Primary heart tumours are extremely rare. Over a period of 25 years 22 primary cardiac tumours were diagnosed clinically or at autopsy at Groote Schuur Hospital. Fourteen patients with myxomas, 1 with lymphocytic lymphoma and 2 with haemangiomas underwent surgery. A further 4 myxomas and 1 histiocytoma were found at autopsy. In both the cases of haemangioma the diagnosis of a vascular tumour was made before surgery. One tumour had infiltrated the lateral wall of the left ventricle and was unresectable; only a biopsy specimen was taken. The patient, however, remains well some 6 years later. In the second patient the haemangioma was situated in the outflow tract of the right ventricle and was successfully excised. The clinical history, pathological features and management of both cases are presented.
