Hahn, Kirsten; Conze, Theresa M.; Wollanke, Bettina; Distl, Ottmar; Goehring, Lutz S. und Witte, Tanja S. (2021): Urogenital Hypoplasia and X Chromosome Monosomy in a Draft Horse Filly. In: Journal of Equine Veterinary Science, Vol. 96, 103318

Abstract

A 5-month-old draft horse filly was presented with incontinence and severe perivulvar dermatitis, which developed during the previous 2 months. Left-sided ectopic ureter entering in the caudal vaginal lumen, signs of cervix hypoplasia, and urine accumulation in the uterus were found during initial vaginal endoscopy. Therefore, a left ureter-nephrectomy was conducted under general anesthesia. Additionally, a cytogenetic examination was performed, which showed a XO monosomy with a 63,X/64,XX mosaic. This is the first case report presenting a chromosome abnormality in a draft horse filly combined with a left sided ectopic ureter. Cytogenetic evaluation is recommended in any female horse with developmental abnormalities of the cervix, uterus, ovaries, or with irregularities of estrus. (C) 2020 Elsevier Inc.
