Surgical Management of Penile and Preputial Neoplasms in Equine with Special Reference to Partial Phallectomy.

Abstract: Penile and preputial neoplasia in horses occurs infrequently and represents diagnostic and therapeutic challenges. The present study was carried out on a total number of 21 equids (14 stallions and 7 donkeys) suffered from different penile and preputial neoplasia. Diagnosis of neoplasms was based up on history of the case, clinical examination as well as histopathological evaluation. Animals with penile and preputial neoplasms were underwent local excision and partial phallectomy with a slightly modified version of the techniques described by William's. The diagnosed neoplasms were penile and preputial squamous cell carcinomas (SCCs; n = 15); sarcoid (n = 4); a-fibrosarcoma; and a melanoma. Local excision was curative in all cases except 5 stallions with SCCs. These stallions had extensive damage of the glans penis, free part of the penis and the inner lamina of the internal fold of the prepuce, and they underwent a partial phallectomy with successful outcome. Follow-up information was obtained by visit and telephone inquiries. In conclusion, penile and preputial neoplasms are commonly encountered in elderly male horses and SCCs are the most common type affecting male external genitalia. Partial phallectomy is effective for management of equine neoplasia if they are confined to the glans and body of the penis and there is no proximal spread or involvement to regional lymph nodes.

The study investigates the occurrence, diagnosis, and treatment of penile and preputial neoplasms in horses and donkeys, concluding that surgical procedures, including partial phallectomy, are effective methods for management of this type of cancers if they are confined and have not spread to regional lymph nodes.

Overview of the Research

  • The research involved 21 equids, which included both stallions (14) and donkeys (7). All these animals were suffering from different types of penile and preputial neoplasms.
  • The team diagnosed the neoplasms based on the animals’ history, clinical examination, and histopathological evaluation, which is a microscopic examination of tissue to study the manifestations of the disease.

Types of Diagnosed Neoplasms

  • From the diagnosed neoplasms, 15 were penile and preputial squamous cell carcinomas (SCCs), 4 were sarcoids, one was a fibrosarcoma, and one was a melanoma.
  • The SCCs were the most common type affecting male external genitalia, especially in elderly male horses.

Surgical Management

  • The animals with these neoplasms underwent local excision and partial phallectomy, a surgical procedure of removing a part of the penis. This was based on a slightly modified version of the techniques described by William’s.
  • Local excision was curative in all cases, except five stallions with SCCs. These stallions had extensive damage of the glans penis, the free part of the penis, and the inner lamina of the internal fold of the prepuce. Consequently, they underwent a partial phallectomy which resulted in successful outcomes.

Follow-up and Conclusion

  • Follow-up information was obtained through visits and phone inquiries to monitor the progress of the horses and donkeys after the surgeries.
  • The conclusion drawn was that penile and preputial neoplasms can be suitably managed through partial phallectomy, if the neoplasms are confined to the glans and body of the penis and there is no proximal spread or involvement to the regional lymph nodes.
