Case report: squamous cell carcinoma of the urinary bladder in a horse.

The study reports on a rare case of squamous cell carcinoma found in a 14-year-old Hanoverian gelding’s urinary bladder, which was initially marked by signs of difficulty in urination and unusual dark red urine after exercise.

Case Presentation

• The subject of the study was a 14-year-old gelding of the Hanoverian breed, who presented with a history of straining during urination and the production of dark red urine following exercise. These symptoms had persisted over a span of 10 weeks.
• The horse had undergone physical examination and no abnormalities were detected from these assessments.

Clinical Findings

• Upon the initial examination, urine samples were taken and analyzed. An abnormality detected was high protein concentration in the urine, measured at 500 mg/dL, when the standard range should be less than 100 mg/dL.
• Besides high protein levels, few red blood cells were also observed in the urine sample.
• Two weeks into the clinical manifestations, the researchers performed an ultrasonography, which showed no irregularities in the kidney or urinary bladder of the horse.

Treatment and Management

• In an attempt to manage the horse’s condition, the researchers suggested vitamin C supplementation, with the aim to acidify the urine.
• The horse was also provided with a salt block to encourage increased water intake.

Conclusion

• The study documents an unusual case of squamous cell carcinoma in a horse’s urinary bladder, a condition seldom observed in this species. Evidence collected from physical examination, urine analysis, and ultrasonography helped to identify this rare instance.
