[The recurrence of a right atrial myxoma. Apropos a case].

Cardiac myxomas are the most frequent cardiac tumor and they have the capability for growing again years after resection. We have recently reviewed such cases at the Instituto Nacional de Cardiología "Ignacio Chávez" and no cases of recurrence of these tumors was detected. In this paper we inform a case that had recurrence of the tumoral mass 4 years after successful resection of the primary one. There were two masses in the right atrium of different sizes. To our knowledge this is the first case with this characteristic.
