Plain-English summary

A 10-year-old neutered domestic shorthair cat was brought in with a painful lump in its mouth that was bleeding and not improving after dental treatment. The vet discovered that the cat had leishmaniosis, a disease caused by a parasite, which was affecting its oral health. After starting treatment with allopurinol, the cat's oral symptoms improved significantly. It's important for pet owners to recognize that oral issues can sometimes be linked to leishmaniosis, especially in areas where the disease is common.

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 ofsp and molecular tests were able to identify. 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.
