Surgical management of penile sarcoid in a stallion.
Abstract: This report describes surgical management and breeding implications of a case of penile sarcoid associated with penis laceration in a 4-year-old Kurdish stallion. A large fleshy mass on the distal end of the penis that resulted in urethral meatus deviation and dysuria was detected in a physical examination. No evidence of local extent or metastasis was detected. Under general anaesthesia, the involved distal portion of the penis was removed through partial phallectomy. Histopathological examination of the mass confirmed a fibroblastic sarcoid. Partial phallectomy was successful for management of penile sarcoid and resulted in no postoperative complications or tumour recurrence in long-term follow up; however, successful ejaculation and semen collection have not been achieved.

This research discusses the surgical procedure and breeding consequences of treating a penile sarcoid associated with a penis injury in a young Kurdish stallion. Despite the surgery being successful and showing no signs of complications or tumor regrowth, the horse was unable to successfully ejaculate or collect semen.
Understanding Sarcoid and the Case Study
- A sarcoid is a common type of skin tumor found in horses, and in this case study, it is found on the penis of a 4-year-old Kurdish stallion. The tumor caused urethral deviation and dysuria (painful or difficult urination).
- Upon diagnosis, no evidence of the tumor spreading locally or metastasizing (spreading to other parts of the body) was found. It was decided that surgical intervention was required.
Surgical Intervention
- The affected part of the penis was removed through a procedure known as partial phallectomy. This was done under general anesthesia.
- An examination of the tumor under a microscope (histopathological examination) confirmed it as a fibroblastic sarcoid. Fibroblastic sarcoids are one of the five types of horse sarcoids and are characterized by their aggressive and invasive growth.
Postoperative Observations and Limitations
- The study reports the surgery to have been successful in managing the penile sarcoid. Following the surgery, there were no postoperative complications and no recurrence of the tumor found in long-term follow-up, which is a positive outcome.
- Despite the successful medical treatment, a significant breeding limitation was noted. The stallion had not been able to ejaculate or collect semen post-surgery. This poses a big problem since the stallion’s ability to breed is affected, which could have larger implications if the stallion was intended for breeding purposes.
Conclusion
- This case highlights the effective use of partial phallectomy in the management of penile sarcoids. It also sheds light on the possible aftermath of the surgery, including the potential effects on the breeding capabilities of the stallion.
