폴로 포니 원위 음경 편평세포암의 외과적 관리 — 변형 William 부분 음경절제

This report describes the successful management of a 14-year-old pony gelding diagnosed with squamous cell carcinoma (SCC) of the distal penis. The patient presented with avulsion of the glans and a proliferative mass, associated with preputial edema, necrosis and dysuria. Preoperative evaluation included physical examination and laboratory diagnostics. Given the severity of the lesion, immediate partial phallectomy was performed using a two-stage modified William’s technique designed to relieve suture tension and minimize postoperative complications. Postoperative management was also critical: a developing preputial hematoma was managed with prompt stab incision drainage, and edema was controlled with a comprehensive plan of multi-modal pharmacological therapy and controlled exercise program. The combination of this modified surgical approach and proactive postoperative care led to resolution of the primary lesion and restoration of urinary function without severe complications. This case highlights this multi-faceted strategy as a practical and effective approach for veterinarians encountering advanced penile SCC in equids.
