Epitheliotropic cutaneous lymphoma (mycosis fungoides) in a coati.
The aim of this report was to present a case of epitheliotropic cutaneous lymphoma (mycosis fungoides) in a coati. The animal was presented for evaluation of a non-pruritic nodule. Although the diagnosis of cutaneous histiocytoma was made histologically, plaques and erosions appeared in new areas of the skin along with rapid deterioration of body condition that led to euthanasia in less than one month following initial presentation. Epitheliotropic cutaneous lymphoma was confirmed with plaque biopsies. Cross-reactivity of a polyclonal antihuman CD3 antibody to coati T lymphocytes was also observed. Apart from skin lesions, only pleuritis was post-mortem diagnosed most likely because of immunosuppression secondarily to malignant neoplasia.
