- Abstract: The sarcoid is a locally invasive neoplasm and it is described as the most common tumor of equines and having an incidence ranging from 12.9% to 67%. Sarcoids have a significant impact on the health and well-being of Equidae and can represent a serious economic-genetic loss when they affect the reproductive system, particularly in subjects with important blood lines and particular morphological value. We describe a neoformation on the external genitals was observed in a Murgese stallion. The stallion was in excellent general conditions and showed no abnormalities, at general examination, while examining the genital apparatus, a large neoformation on the external genitals was observed. On palpation and ultrasonographic examination, the glans of the genital apparatus were normal. External physical examination showed a hyperkeratotic proliferative-verrucous neoformation, both ulcerated and infected. Clinical appearance was suggestive of proliferative cutaneous lesions as sarcoids and/or summer sores. Surgical treatment was achieved with a segmental posthetomy, performed with the horse anesthetized and in dorsal recumbency, as previously described. The dimensions of the stretched mass were about 22 x 11 centimeters and weighed 600 grams. Histopathological examination allowed a tissue level diagnosis of an equine sarcoid, but the excised mass was also positive to species-specific PCR for Habronema microstoma, a frequent cause of cutaneous and mucocutaneous habronemiasis. After two-year post-surgery the stallion is normally employed in breeding season. The collection of seminal material with an artificial Missouri vagina and during two jumps were carried out one hour apart, whose parameters and their characteristics resulted within physiologic ranges. The fertility data provided were excellent. In the described clinical case, segmental posthetomy, a specific procedure for neoformations of the internal preputial lamina, proved to be valid in the treatment of a large circumferential sarcoid located on the outer lamina of the fold and the preputial ring, with minimal complications.
