Cardiac tumors pathological findings

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.
