| Zusammenfassung: | Meagre juveniles (Argyrosomus regius) maintained in experimental conditions for 3 weeks developed a lateral and/or bilateral circular shape sarcoma at the opercular cavity. The sarcoma was dense, reddish and its growth from the branchial arch towards outside forced the opening of the operculum. Histologically the neoplasm exhibited intense proliferation of mesenchymal connective tissue, often fusiform, which developed in a solid pattern accompanied by abundant mononuclear cell forms. Also observed were areas of discrete necrosis, compatible with a sarcomatous proliferation characteristic of a thymus lymphoma |
