Background: Papillomas are cutaneous neoplasms, also known as warts. They are usually benign and are caused by apapillomavirus. The development of papillomas in certain locations on the body may cause irreparable consequences.Paraphimosis is a urological emergency characterized by the inability of the penis to retract or the impossibility of retentioninside the foreskin, causing local circulatory disorders and severe pain. However, the association between genital papillomas and the development of paraphimosis in horses has not been previously documented. The objective here is to describethe clinical and histopathological aspects of a case of penile papilloma associated with persistent paraphimosis in a horse.Case: A 15-year-old mixed-breed, 350 kg, horse presented nodular and crusted lesions, similar to warts, on the penis andforeskin, which progressed over at least 6 months. An incisional biopsy of one of the nodular lesions of the horses peniswas performed. Tissue fragments were collected, packed in 10% buffered formaldehyde, and sent for histopathologicalevaluation to the Animal Pathology Laboratory of the University Veterinary Hospital of the Federal University of CampinaGrande (UFCG), Campus de Patos, Paraíba. The biopsy resulted in a histopathological diagnosis of papilloma, and thehorse was reevaluated. Due to the severity of the clinical case, it was referred to the HVU/UFCG Large Animal Medicaland Surgical Clinic for surgical removal of the penis. The penectomy product was sent to the Animal Pathology Laboratory. Macroscopically, the penis fragment measured 18.0×10.5×6.0 cm in size, had an irregular surface, and presented withnumerous multilobulated, reddish nodules on a sessile base, which were exophytic with projections having the appearanceof a “cauliflower.” The nodules extended from the foreskin and compromised from...(AU)
