A 2.5-year-old, female pallid bat (antrozous pallidus) was captured in
Oregon (USA) in 1990 and later died in 1992. At the time of death, ab
dominal distension due to ascites, splenomegaly, and hepatomegaly, and
a cheek mass were noted. Based on histologic examination of these tis
sues, a diagnosis of multicentric lymphoma was made. Retroviral partic
les were not found on electron microscopic examination.
