Atrial myxoma associated with multiple hamartomas

A case of cardiac myxoma associated with renal angiofibrolipomas, renal medullary fibromas, thyroid adenoma and jejunal polyp was presented. So far as we know, the combined form of cardiac myxoma and renal hamartoma has not been hitherto reported. The combination of these various complications may suggest the relationships of tuberous sclerosis, Cowden disease, lymphangiomatosis among others. Besides it is noteworthy that the three of them, i.e. cardiac myxoma, renal angiofibrolipomas and thyroid adenoma, presented considerable atypism at the same time. As to the histogenesis of cardiac myxoma, this case may be in accord with the hamartoma theory.
