Guanophoroma in the Red Sea silverside Atherinomorus lacunosus (Perciformes, Atherinidae)

Colorni A

The occurrence of a spontaneous tumor affecting the guanophore iridocytes of the Red Sea silverside Atherinomorus lacunosus is described. The tumoral mass consisted mainly of yellowish, light-reflecting guanine platelets. The tumor infiltrated the fibers of the underlying muscle tissue, growing in whorls around them. A delicate network of capillaries provided the tumor with a blood supply. No viral particles were observed. This rare form of tumor is the first of this kind reported in a feral fish from the Red Sea.
