Plain-English summary
An 11-year-old male mixed-breed dog was brought to the vet because of a noticeable lump near his rear end. Tests revealed that the lump was a perianal gland adenoma (a type of tumor) and also showed the presence of Leishmania parasites, which can cause a disease called leishmaniasis. This unusual case highlights how the parasites can sometimes spread in unexpected ways. The dog was diagnosed with leishmaniasis and received appropriate treatment, but the specific outcome of his recovery wasn't detailed.

Abstract
The coexistence of Leishmania and neoplasia is rarely reported in humans or animals. An 11-year-old intact male mixed-breed dog was presented with a well-demarcated perianal nodule. Cytologic and histopathologic examinations were consistent with the diagnosis of perianal gland adenoma with the presence of Leishmania amastigotes. The dog was considered to be in leishmaniasis stage C (clinically diseased) based on clinical signs, laboratory findings, and serological status. A novel finding in this case report was the presence of Leishmania within the perianal adenoma, probably resulting from an atypical dissemination of the parasites.
