Ocular lymphosarcoma of an Atlantic cod, Gadus morhua.

Abstract

Johnstone (1912, Report for 1911, Lancashire Sea Fisheries Laboratory 20: 33-74) described a lymphosarcoma involving the choroid layer of the eye in a flounder, Pleuromiectes flesus. Plehn, (1924, Praktikum der Fischkrankheiten, E. Schweizerbort’sche Verlagsbuchlandlung, Stuttgart) reported abdominal lymphosarcoma of the goldfish Carassius auneatus. Three other lymphomas involving the abdomen, with site of primary origin unknown, have been observed in the herring (Clupea harengus), the Conger eel (Comiger comiger), and Rasbora latenistriata (Johnstone, 1926, Proc. Trans. Liverpool Biol. Soc. 40: 75-98;
