Cardiac lithomyxoma.

Abstract

Among 102 consecutive cardiac myxomas, 10 (10%) showed heavy calcification both on gross inspection and on x-ray examination. Mineralization was partial in 6 patients (mean age 56.8 years) and massive stone-like in 4 (mean age 70 years); relevant histologic findings in patients with partial calcification were Gamma-Gandy bodies in 5, cartilaginous and bone metaplasia in 2, and aspecific calcium deposits in 1. All were incidental findings either at autopsy or during clinical investigation.
