Plain-English summary
A 12-year-old male mixed-breed dog was brought to the vet because he was not eating, vomiting, and had several lumps on his neck, trunk, and hind legs. Tests showed that these lumps were likely caused by cancer that had spread from his stomach. Unfortunately, after he passed away, a thorough examination confirmed that he had a type of stomach cancer called mucinous adenocarcinoma, which had spread to his skin. This case highlights a rare instance of stomach cancer affecting a dog's skin.

Abstract
A 12-year-old, intact, male mixed-breed dog was presented with anorexia, vomiting and multiple cutaneous nodules on its neck, trunk and hindlimbs. Fine-needle aspiration cytology of the nodules was characterised by a pleomorphic population of cells arranged singly or in small cohesive clusters, embedded in an amorphous mucinous material stained positive by periodic acid-Schiff (PAS). Acinar structures were occasionally found. Cells appeared either small with scant basophilic cytoplasm or large with a histiocytic appearance. Large cells had cytoplasm filled with a PAS-positive granular material. A presumptive diagnosis of cutaneous metastases of a mucinous adenocarcinoma was made. A primary, gastric, signet-ring mucinous adenocarcinoma was confirmed at postmortem examination and by histopathology. To the authors' knowledge, this is the first report of a gastric mucinous adenocarcinoma with cutaneous disseminated metastases in a dog.
