Testicular Tumors Associated with Mammary , Prostatic , and Other Changes in Cryptorchid Dogs

چکیده
Cases of unilateral or bilateral cryptorchidism in dogs are only occasionally seen by breeders and are apparently quite infrequent. Vennerholm (1897), a veterinarian of wide experience, reported having encountered six such cases in his extensive practice, three of which were inguinal and three intra-abdominal. The same author stated that one specimen of unilateral and one of bilateral cryptorchidism in the dog are preserved in the anatomical museum of the Institute for Veterinary Medicine in Stockholm. It may be assumed that the undescended testes in Vennerholm's cases showed no externally discernible pathological change, since it seems reasonable to suppose that he would have mentioned them had any such been present. So far as the present writers have been able to determine, there is no published report of testicular tumors in cryptorchid dogs in which the condition was associated with the abnormal enlargement of the mammary papillae, prostatic metaplasia, and the other remarkable features present in the two animals about to be described.

Cryptorchidism is symptomatic of underlying testis dysgenesis. Precise terminology is important to distinguish and understand three phases of testis descent. Abdominal translocation involves holding a testis near the internal inguinal ring plus slight d...

BACKGROUND:Canine mammary gland cancers are the most prevalent malignancies in dogs. There are different challenges regarding management of these cancers in dogs and human, one hypothesis is related to small cellular subset of tumor mass called cancer stem cell. These cells are therapy resistant and cause metastasis and relapse even after primary successful treatment. The well-identified phenot...
