Tumor de células de la granulosa en una yegua española de 4 años.

Abstract

The granulosa cell tumor (GCT) of the ovary is a unilateral presentation pathology in most cases, which is why it is associated with serious reproductive problems. GCT has a high prevalence in the equine population of Ganadería de la Costa Ltda., Therefore, a case study on GCT in a 4-year-old Spanish nulliparous mare that entered anestrum for approximately one year is presented, observing Behaviors similar to that of a stallion, with virilism and high aggressiveness towards the males present in the paddock. The transrectal ultrasound examination was used as a diagnostic approach to identify the possible neoplastic ovary. Finally, the therapeutic resolution was based on ovariectomy as a surgical treatment, proving to be satisfactory, observing behavioral and reproductive changes, hoping that in later years it could be part of the reproductive programs of the company.
