Abstract

Canine visceral leishmaniasis (CVL) is a disease with multisystemic injuries, and among the varioustissues affected, the third eyelid (TE) is often involved. This ocular adnexa has been studied for theleishmaniasis pathogenesis elucidation and for diagnosis advance. This study aimed to carry out theparasite immunodetection and evaluate histologic lesions in TE of Leishmania (leishmania) chagasinaturally infected dogs. Twenty-six TE samples from infected dogs were submitted to histologicevaluation and to immunohistochemistry for Leishmania sp. The main lesion observed in the thirdeyelid conjunctiva (TEC) was lymphoplasmacytic inflammation, with Mott cells and parasitizedhistiocytes. Additionally, loss of epithelial stratification, ulceration, goblet cells thinning or hyperplasiawere often found. The same inflammatory pattern was observed in the third eyelid lacrimal gland(TELG), often accompanied by acinar atrophy and secretory ducts dilatation. Immunohistochemistry revealed parasitism in all samples, in different intensities.

Keywords: canine visceral leishmaniasis; conjunctiva; dog; eye; lacrimal gland.
