Infant cardiac fibroma with clonal t(1;9)(q32;q22) and review of benign fibrous tissue cytogenetics.
Cardiac fibromas are rare lesions which occur more frequently in infants and children than in the adult population. These tumors are nonmalignant proliferations of connective tissue most often found in the left ventricular myocardium or septal myocardium. No cytogenetic studies of cardiac fibromas have been reported. We report a case of an infant with a subepicardial tumor in whom the cytogenetic analysis showed a clonal reciprocal translocation, 46,XY,t(1;9)(q32;q22),inv(9)(p11q12)c. We review the literature regarding cardiac fibromas and briefly discuss the cytogenetics of benign fibrous neoplasias.
