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.

Keywords: partial phalectomy; penis; sarcoid; stallion.
