Conjunctival/third eyelid (TEL) tissues may be affected by lymphoma (*see also cutaneous epitheliotropic, corneoscleral, uveal & chorioretinal lymphoma and retrobulbar neoplasia). In some cases ocular and/or adnexal symptoms may be the initial presentation for more generalized disease, however conjunctival/TEL lymphoma may also represent localized disease. Clinical findings may encompass a spectrum of changes from conjunctical/TEL hyperemia to tissue infiltration and/or nodular and/or diffuse cream-colored mass formation. Both canine & feline species of any breed or crossed-breed may be affected.
