Non-neoplastic tumors are rarely found in the heart. Calcified amorphous tumor [CAT] of the heart is one such tumor. When present, it is often mistaken for a calcified myxoma, thrombus, vegetation or malignancy. It is found subendocardially with areas of calcification in an amorphous degenerating fibrin background causing obstruction to the outflow tracts. It has to be excised and subjected for histopathological examination to confirm its diagnosis. We found a CAT in an eight-year-old boy who was being evaluated for fever of unknown origin. Heterogenous tumor masses were found in the right ventricle and right ventricular outflow tract. These masses had embolised further into both the left and right pulmonary arteries. Surgery was done on conventional cardiopulmonary bypass and all the tumor masses were excised. Histopathological examination revealed features consistent with CAT. Very few cases of CAT have been reported in the world literature. Resection is curative but if incomplete, recurrences are known to occur.
