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 neo-formation, 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 dor-sal 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 posi-tive to species-specific PCR for Habronema microstoma, a frequent cause of cutaneous and mucocutaneous habronemiasis. Af-ter two-year post-surgery the stallion is normally employed in breeding season. The collection of seminal material with an arti-ficial Missouri vagina and during two jumps were carried out one hour apart, whose parameters and their characteristics re-sulted within physiologic ranges. The fertility data provided were excellent. In the described clinical case, segmental postheto-my, a specific procedure for neoformations of the internal preputial lamina, proved to be valid in the treatment of a large cir-cumferential sarcoid located on the outer lamina of the fold and the preputial ring, with minimal complications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
