Incidence of spontaneous ileocecal immunocytomas in hybrids of LOU/C rats and rat strains with low spontaneous tumor incidence.


Monoclonal immunoglobulin-secreting tumors (immunocytomas or plasmacytomas) appear in many species, but they occur at a low incidence and usually originate in lymphoid tissues. However, in the rat, the incidence of malignant spontaneous immunocytomas (or plasmacytomas) was high and the tumors consistently arose in the ileocecal lymph nodes. In inbred LOU/C… (More)
