Plain-English summary

A 5-year-old male German Shepherd was brought to the vet after being diagnosed with leishmaniasis and having several lumps on his testicles. Tests showed that these lumps were grade II mast cell tumors, which are a type of cancer. The vet performed surgery to remove the affected testicles and surrounding tissue. Seven months later, the dog was doing well with no complications or signs of cancer spreading, giving him a good outlook for the future.

Abstract

A 5-year-old intact male German Shepherd dog was referred with a diagnosis of leishmaniasis. Several testicular masses were palpated during the physical examination, while the diagnostic screening yielded no remarkable findings. Fine needle aspiration cytology of the masses revealed the presence of intermediately differentiated mast cell tumours. Scrotal ablation and orchiectomy were performed as a definitive treatment option. The pathological examination of the surgical specimens confirmed the diagnosis of grade II mast cell tumours and showed that they were all confined to the testicular capsule. At 7 months post-admission, the dog exhibited neither postsurgical complications nor metastatic foci and was, therefore, given a favourable prognosis. Despite their exceptionally rare occurrence, mast cell tumours should be considered for the differential diagnosis of testicular tumours.
