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.
