Plain-English summary
A 16-year-old Quarter Horse stallion that had an undescended testicle (cryptorchid) was experiencing colic, which is a type of abdominal pain. During surgery, veterinarians found and removed two large, lumpy masses near the pelvic area. Unfortunately, one of the masses damaged a major blood vessel, leading to severe blood loss, and the horse did not survive. A later examination showed that the masses were malignant seminomas, a type of cancer, and that the cancer had spread to other areas in the abdomen.
Abstract
A 16-year-old cryptorchid Quarter House with colic had a large, lobulated soft-tissue mass to the left of the pelvic inlet. At surgery, 2 large multilobulated pedunculated masses were removed. A large blood vessel enveloped by one of the masses was damaged, and the horse exsanguinated. Postmortem examination of the abdomen revealed the masses to be malignant seminoma, with multiple sites of metastasis.
