Alerts clinicians to CAT in mitral annular calcifications among hemodialysis patients; case report leaves open need for prospective screening studies.
We report a case of calcified amorphous tumor (CAT) of the heart in a 60-year-old Japanese man on hemodialysis. Because the masses in the mitral annulus developed during two-year echocardiographic follow-up, he underwent surgical resection with mitral valve replacement. Histological examination showed that the tumor contained multiple calcified nodules, which confirmed the diagnosis of CAT. This case report reinforces the need to deeply and periodically investigate for cardiac involvement of CAT in all patients on hemodialysis.

Takeuchi et al. (2016) conducted a case report in Calcified amorphous tumor of the heart (n=1). Surgical resection with mitral valve replacement was evaluated on Histological diagnosis of calcified amorphous tumor. Surgical resection and histological examination confirmed a calcified amorphous tumor in the mitral annulus of a 60-year-old hemodialysis patient after two years of echocardiographic follow-up.
