Plain-English summary
An 11-year-old Thoroughbred mare was found to have a nodular tumor around her right eyelids. To understand how far the tumor had spread, a special scan called a computed tomography (CT) scan was done. The tumor was surgically removed, and then the area was treated with a special vaccine called Bacillus of Calmette and Guerin (BCG), which helps fight tumors. The mare received a total of five injections of this treatment over a period of 10 weeks. At a follow-up appointment seven months after the last injection, the tumor was completely gone, and two years later, she still shows no signs of it returning.
Abstract
A periocular nodular sarcoid of the right upper and lower eyelids was diagnosed in an 11-year-old Thoroughbred mare. Computed tomography scan revealed the extent of the tumor. The mass was surgically debulked under general anesthesia, and the affected periocular region was injected intralesionally with Bacillus of Calmette and Guerin (BCG). An emulsion of cell wall fractions was used, which has been modified to reduce the toxic and allergic effect, but retain the antitumor activity. In total, five injections were performed at 2-week intervals. At follow-up 7 months after the last BCG injection, the tumor was completely resolved. Two years after the last treatment, the horse remains tumor-free.
