Plain-English summary
A 12-year-old male Maltese was found to have a mass in his spleen during a routine check-up. The veterinarian performed surgery to remove the spleen (splenectomy), and the mass was identified as a rare type of cyst called a splenic epidermoid cyst. This condition is uncommon in dogs, and the dog recovered well after the surgery.

Abstract
Splenic epithelial cysts are rare in humans and have not been reported in animals, to our knowledge. During a routine medical examination of a 12-y-old castrated male Maltese dog, a splenic mass was found and subsequently removed via splenectomy. Histologically, a well-defined multilocular cyst in the spleen was lined mostly by simple cuboidal, multifocally by stratified cuboidal, or occasionally by stratified squamous epithelium. Immunohistochemically, the lining cells were positive for cytokeratin and negative for vimentin, CD31, and Wilms tumor protein 1. The case was diagnosed as a primary splenic epidermoid cyst.
