Lymphosarcoma with lymphoblastic leukemia in a New Zealand white rabbit.

An 8 to 10-week-old female New Zealand white rabbit, Oryctolagus cuniculus, which exhibited clinical signs of anorexia, depression, and torticollis was found to have lymphosarcoma with lymphoblastic leukemia. The multiple visceral involvement with neoplastic lymphoid cells observed in this animal was similar to previously reprted cases of lymphosarcoma in the rabbit. An unusual finding was the occurrence of lymphoblastic leukemia since lymphosarcoma in the rabbit has previously been reported as aleukemic.
