“…Large, prominent nucleoli and cytoplasm with occasional vacuoles were also seen. The cytoplasm is fragile and causes frequent cell disruption and naked nuclei . The high mitotic activity was not found on the cytology slides but were seen on the histopathology sections .…”

“…Cryptorchidism seems to be a predisposing factor . Frequent associations with interstitial or Sertoli cell tumors are described for seminoma in the dog but has rarely been observed in horses …”

“…As there are no published cytologic criteria for testicular tumors in stallions, those described for dogs were applied . Cytology is considered a highly reliable technique for the classification of testicular tumors in dogs …”

Cutaneous metastases of prostatic adenocarcinoma in two dogs

“…There is a high degree of cytologic atypia, and binucleated cells are sometimes present. Necrosis can be found as amorphous basophilic material, and in these cases, cellular features cannot be recognized 12 . In some cases, prostatic adenocarcinoma and transitional cell carcinoma can be difficult to differentiate cytologically; however, the presence of acinar structures might be seen in the glandular tumor types, which could help to differentiate this neoplasm from transitional cell carcinoma 13 .…”
