(B) Cholangiocellular carcinoma replacing entire liver parenchyma. (C) Spermacytic seminoma. (D) Ovotestes. S = seminoma in mesenteries adjacent to mature ovaries. (E) High magnification of seminoma from fish with ovotestes. (F) Chronic aerocystitis. (G) Oophoritis (egg associated inflammation and fibroplasia) X = raft of eosinophilic yolk debris and fibroplasia. (H) Swimmbladder surface with acid bacteria (arrows). (A, H) = 10 μm. (B, C) = 100 μm. (F) = 50 μm. (E) = 25 μm (D, G) = 500 μm. (A–E) = Hematoxylin and eosin. (H) = Fite’s acid fast.
