Plain-English summary
Three dogs were brought in with swollen testicles, which is not typical and raised concerns for their owners. After thorough testing, veterinarians discovered that the swelling was caused by cancer that had spread from the dogs' gastrointestinal tracts to their testicles. This type of cancer spreading to the testes is rare, but it highlights the importance of checking for primary tumors in the digestive system when such symptoms occur. Unfortunately, the presence of metastatic cancer indicates a more serious condition, and treatment options would depend on the extent of the disease.

Abstract
Primary testicular neoplasms are common in dogs, but metastases to the testes are rare. Three dogs had enlargement of the testes and associated structures. Upon histological examination, the enlargements were due to metastatic adenocarcinomas. Further examination identified the gastrointestinal tract as the primary site of the metastatic neoplasms in all three cases. The testicular metastases reflected widespread metastatic disease. When metastatic adenocarcinoma is found in the testes and associated structures in dogs, the gastrointestinal tract should be examined closely for a primary tumor site.
