Abstract:
Reports of spontaneous hematopoietic neoplasms in Platyrrhines species are scarce. We present the gross, histological, and immunohistochemical findings of disseminated T-cell lymphoma in a male 25-year-old Sapajus xanthosternos kept in a Brazilian conservation center. No molecular evidence of betaherpesvirus or gammaherpesvirus was associated with the occurrence of this neoplasm.
