Prostatic carcinoma diagnosed by FNA: Our Case Of The Month October 2014

A 15-year-old MN West Highland White terrier dog was presented for evaluation of polydipsia, polyuria and possible bladder stones noted on radiographs. Abnormalities on CBC and serum biochemistry were thrombocytosis, neutrophilia, and hyperalbuminemia. Urinalysis was not performed owing to financial constraints however an abdominal ultrasound prescription was approved.

DX

Prostatic carcinoma.

Outcome

Client was considering euthanasia as the patient was not doing well. No further outcome was provided.

Comments

Empirical therapy with Deramaxx and enrofloxacin was recommended until an oncology consultation could be considered.

Clinical Differential Diagnosis

Polydypsia – bladder pathology (uroliths, neoplasia, chronic cystitis, bacterial cystitis), prostatic neoplasia, renal pathology (early chronic kidney disease, neoplasia, pyelonephritis).

Sampling

U/S guided FNA was performed. Cytology of the prostatic mass revealed carcinoma.

Sonographic Differential Diagnosis

These images are suggestive of a mineralizing prostatic mass as opposed to luminal urethal calculi. Specifically carcinoma is suspected.

Image Interpretation

The prostate revealed a large mineralizing mass that measured 4.4 x 2.7 cm with extrusion of the mass into the pre-prostatic urethra. Prostatic capsular expansion and distortion is noted.
