• 

  HEART: Metastatic Tumor: Gross very unusual large metastatic carcinoid in right atrium

• 

  Cardiac Myxoma A gelatinous tumor is attached by a narrow pedicle to the atrial septum. The myxoma has an irregular surface and nearly fills the left atrium.

• 

  Cardiac Myxoma There was a calcified right atrial mass on the X ray of a 47-year-old man. Resection demonstrated a smooth-surfaced tumor. The gritty material seen microscopically on cut section was calcified and ossified myxoma.

• 

  Cardiac Fibroma Cut surface of the tumor shown in figure 6-2. The left ventricular (LV) cavity is present behind the mass. The patient was a 4-month-old child who died suddenly without a previous medical history.

• 

  This tumor was resected from the right atrium of a 1-year-old boy with pericardial effusions. Note areas of hemorrhage and dilated vessels. The patient was well 49 months postoperatively.

• 

  Papillary fibroelastomas are often on the arterial surface and may project into the coronary ostium, causing ostial occlusion. This tumor is in the noncoronary sinus.
