A case report of leishmaniosis with primary oral manifestation in a cat

Abstract

A case of leishmaniosis with primary oral manifestations was reported in a 10-year-old neutered domestic shorthair cat. The primary lesion was a maxillary nodular lesion, painful with spontaneous bleeding associated with advanced periodontal disease, which did not resolve with tooth extraction or periodontal treatment. Biopsy revealed chronic neutrophilic and macrophagic infections and amastigote forms of Leishmania sp and molecular tests were able to identify Leishmania infantum. Oral signs resolved after the initiation of etiologic treatment with allopurinol. Distinguishing oral signs of leishmaniosis from other oral inflammatory diseases is important, especially in endemic areas, and co-infections must be considered with any oral manifestations of this disease.

“…Moreover, granulomatous laryngitis problem associated with L. infantum has also been described in a dog treated with glucocorticoids, and the authors of this case report suggested that immunosuppressive treatment may have led to the onset of the lesion 20 . In the case of cats, the first report of oral lesions in feline leishmaniosis has been recently described in 2022 21 . In general, skin lesions are the most common findings on physical examination in cats with leishmaniosis 22 …”

“…20 In the case of cats, the first report of oral lesions in feline leishmaniosis has been recently described in 2022. 21 In general, skin lesions are the most common findings on physical examination in cats with leishmaniosis. 22 In humans, leishmaniosis is caused by L. infantum and other Leishmania species with mucocutaneous and visceral tropism.…”
