Leishmaniases are a group of diseases caused by protozoa of the genus Leishmania and transmitted mainly by the bite of sand fly vectors. Cats are infected with at least 6 species of Leishmania. Significant associations have been found between feline leishmaniosis and coinfections mainly with FIV and/or FeLV. A 7-year-old castrated male, domestic short-haired cat was presented with unknown history and cutaneous and ocular lesions. A raised, semifirm swelling on the forehead was observed along with periocular hypotrichosis and conjunctival and third eyelid edema. The indications for pursuing a diagnosis of leishmaniosis are variable, and differing presentations may require the use of different tests. Diagnosis of feline leishmaniosis with panniculitis caused by Leishmania infantum was made by cytology, histopathology, and PCR and Leishmania antibodies (IFA). The cat responded to therapy with meglumine antimoniate and allopurinol.
