Feline leishmaniosis is a chronic disease with clinical signs and clinicopathological abnormalities similar to those found in dogs. (Table 6)
The most common cutaneous lesions described are ulcerative and nodular dermatitis mostly distributed on the head or symmetrically on distal limbs (Figures 4 and 5). Uveitis is the most important ocular lesion (Figure 6). Oral lesions consist of nodules (tongue and/or gingival mucosa) or chronic stomatitis (Figure 7).
Complete blood counts (CBC), biochemical profile and urinalysis are required in any suspected case to identify hyperglobulinemia, non-regenerative anemia, renal disease or other less common laboratory abnormalities associated with leishmaniosis.
FIV and FeLV testing are recommended in case of risk of exposure, as well as investigation of other concurrent diseases that alter feline immunity.
