Lymphoma in a rabbit: histopathological and immunohistochemical findings.
Lymphoma is a very common lymphoid neoplasm in domestic animals, but few naturally occurring cases have been reported in rabbits. It presents at different sites within rabbits and, although the macroscopic pattern tends to be similar, different cell populations may be involved. This report describes a case of spontaneous lymphoma ocurring in a two-and-a-half-year-old pet Dutch dwarf rabbit. T and B lymphocyte infiltrates were observed in skin, lung, kidney, liver, intestine and lymph nodes, in each case affecting one or more tissue structures. The diagnosis, based on microscopic and immunocytochemical findings, was multicentric, T cell-rich B cell lymphoma with skin involvement.
