Tumours of the prostate and penis.
Abstract: Tumours of the male genital tract, excluding the testes, are relatively rare in the six major domestic animals. The most important tumours are prostate carcinoma and transmissible venereal tumour of the penis in dogs, fibropapilloma of the penis in bulls, squamous papilloma and squamous cell carcinoma in horses, and squamous papilloma in pigs. Four histological types of canine prostate carcinoma exist: alveolar papillary, acinar, organoid, and poorly differentiated. The biological behaviour of prostate carcinomas is similar to that in man, with frequent metastasis to the regional pelvic nodes, bones, and lungs. There appears to be no relationship between the common diffuse glandular hyperplasia and carcinoma in the prostate of dogs. A unique lesion of dogs is squamous metaplasia of the prostate related to estrogen-producing Sertoli cell tumours of the testis. Three different transmissible tumours of the penis occur in domestic animals. The canine venereal tumours can be transmitted only by intact tumour cells during licking and coital contact, whereas bovine fibropapillomas and porcine squamous papillomas can be transmitted by cell-free material. In cattle, the fibropapillomas are caused by the same virus that produces cutaneous papillomatosis. All three tumours are benign and usually regress spontaneously.

This research article primarily explores the occurrences and characteristics of tumors in the male genital tract in six major domestic animals, emphasizing on prostate carcinoma and transmissible venereal tumors in dogs, fibropapilloma in bulls, squamous papilloma and squamous cell carcinoma in horses, and squamous papilloma in pigs.
Types of Tumors
- The primary focus of the study is on prostate carcinoma and transmissible venereal tumor of the penis in dogs, fibropapilloma of the penis in bulls, squamous papilloma and squamous cell carcinoma in horses, and squamous papilloma in pigs.
- It seeks to create an understanding of four histological types of canine prostate carcinoma: alveolar papillary, acinar, organoid, and poorly differentiated.
- It also discusses a unique lesion in dogs i.e., squamous metaplasia of the prostate, which is linked to estrogen-producing Sertoli cell tumors.
Characteristics of the Tumors
- The biological behavior of prostate carcinomas in animals aligns with that in humans – frequent metastasis to regional pelvic nodes, bones as well as lungs.
- While the most common diffuse glandular prostate hyperplasia in dogs seems to have no association with carcinoma, squamous metaplasia of the prostate in dogs is linked to the estrogen-producing Sertoli cell tumors of the testis.
Transmission of Tumors
- Three transmissible tumors of the penis have been identified in domestic animals. Here, the method of transmission differs. Canine venereal tumors can only be transferred via intact tumor cells through coital contact or licking.
- In contrast, bovine fibropapillomas and porcine squamous papillomas have the potential to be transmitted via cell-free material.
Disease Trajectory and Prognosis
- The fibropapillomas in cattle are caused by the same virus that results in cutaneous papillomatosis.
- All three predominantly benign penis tumors typically regress spontaneously over time.
