Plain-English summary
A group of 92 male dogs with testicular tumors underwent fine needle biopsies to identify the type of tumor. The most common types found were Leydig cell tumors, seminomas, and sertoliomas. The results from the biopsies were confirmed through surgery in most cases, showing that this method of diagnosis is very accurate. If your dog is diagnosed with a testicular tumor, it's important to discuss treatment options with your veterinarian, as surgery is often necessary for removal.

Abstract
In this paper, we report on our experience of cytology of fine needle biopsies performed on 92 dogs with testicular tumours during the period from 1998 to 2002. Cytological diagnosis was consistent with seminoma in 20 cases, sertolioma in 16 cases, Leydig cell tumours in 50 cases and mastocytoma in one case. Five cases could not be diagnosed by cytology. Cytological observations were confirmed after surgery by histopathological examination in 87 cases. Cytology provided a sensitivity of 95% for seminoma, 88% for sertolioma and 96% for Leydig cell tumours. The specificity was 100% for all three tumour types. In our experience cytology of fine needle aspirations of testicular tumours is a very reliable technique.
