reticuloendotheliosis

[ritik′yəlō·en′dōthē′lē·ō′sis]
an abnormal condition characterized by increased growth and proliferation of the cells of the reticuloendothelial system. See also reticuloendothelial system.

reticuloendotheliosis

a superseded term for neoplasia of hemopoietic precursors. See also blast form of erythremic myelosis.

avian reticuloendotheliosis
a group of diseases of poultry caused by the REV group of retroviruses, and includes a chronic neoplastic disease of turkeys and chickens, a runting disease in chickens accidentally injected with the virus, and possibly an acute reticulum cell neoplasia. The chronic neoplasia is manifested by nodular tumors in visceral organs.
feline reticuloendotheliosis
leukemic reticuloendotheliosis
leukemia marked by splenomegaly and by an abundance of large, mononuclear abnormal cells with numerous, irregular cytoplasmic projections that give them a flagellated or hairy appearance in the bone marrow, spleen, liver and peripheral blood; called also hairy-cell leukemia.
