Prostatic adenocarcinoma in a schnauzer Dog

Abstract

An eight-year-old, castrated male, a Schnauzer dog was presented with dysuria, hematuria and intermittent vomiting. Retrograde positive contrast urethrography was performed under fluoroscope. On the contrast examination, the leakage was observed in the prostatic urethra region and irregular filling defect was also shown from the prostatic urethra and the level of the trigon of the bladder. Surgical treatment was selected because of partial urethral obstruction and dysuria. The metastasis at the time of surgery was suspected, and the owner decided euthanasia. We detected lymph metastasis with immunohistochemical staining for pan-cytokeratins (CK) AE1/AE3, confirming their epithelial origin. This report described typical clinical findings, diagnostic imaging and histopathological examination of a prostatic adenocarcinoma.
