title: Intracardial mesotheliomas and a gastric papilloma in a giant grouper, Epinephelus itajara (Lichtenstein).

The principal necropsy findings consisted of multiple tumors in the ventricle of the heart, a tumor mass in the stomach, and protozoa-like organisms in the heart tumor, bile ducts and kidney collecting ducts.
