Plain-English summary
A 16-year-old thoroughbred stallion suddenly developed swelling in his left testicle. He had previously been considered a unilateral cryptorchid, meaning he had one testicle that did not descend. An ultrasound showed that the left testicle had an unusual appearance, with areas that looked different from normal tissue, and no healthy testicular tissue could be found. A thin band around the testicle suggested there was a capsule-like structure. The final diagnosis was a seminoma, which is a type of testicular tumor.
Abstract
A 16-year-old thoroughbred stallion developed sudden swelling of the left testicle. The stallion had previously been regarded as a unilateral cryptorchid. Ultrasound examination of the left testicle revealed a diffusely heterogeneous parenchyma. The testicle was diffusely hypoechoic with ill defined regions of hyperechogenicity giving the appearance of hypoechoic nodules throughout the testicular parenchyma. No normal testicular tissue was identifiable. An echogenic band, representing a pseudocapsule could be seen surrounding the testicle. Histopathologic diagnosis a seminoma.
