A 14 year old male Poodle presented for history of possible retained testicle. Clinical exam revealed an empty scrotal sac and lack of typical incision scar from neuter surgery. Rectal palpation revealed a prominent prostate.

This prostatic presentation is most consistent with benign prostatic hyperplasia with possible chronic active prostatitis, secondary to persistent androgen production from cryptorchid testicles. The dog is a bilateral cryptorchid with the left testicle in the inguinal ring. The right testicle cranial right at the urinary bladder, and the loss of detail could represent an emerging Sertoli cell tumor.
The prostate demonstrated relatively uniform enlargement with some urethral impingement. Nebulous hyperechoic parenchyma intercalated with focal hypoechoic changes is suggestive of either chronic inflammatory episodes, benign cystic pathology or both. Underlying neoplasia is possible but lower on the differential list. No overt abscess or obvious neoplasia was present. The prostate measured 2.3cm in diameter. A right cryptorchid testicle was present at the level of L4 to the cranial right position of the urinary bladder apex. This measured 1.7cm with a mild amount of structural loss. The left inguinal ring demonstrated a second left cryptorchid testicle measuring 1.4cm adjacent to the prostate.
Bilateral orchiectomy was performed. The left testicle was removed through an inguinal incision, and the right intraabdominal testicle was removed through the linea alba.
Fine needle aspirate or a biopsy (preferred) following coagulation assessment would need to be performed on the prostate in order to define the pathology at the cellular or structural level respectively, and in order to definitively rule out neoplasia.
Bilateral cryptorchid, testicular agenesis/hypogenesis, neutered male with non visible scar and residual prostatic disease (carcinoma, abscess, prostatitis, hypertrophy owing to ectopic androgen treatment).
