Plain-English summary
A 1-year-old mixed-breed dog was found to have unusual growths called hyaline ring granulomas in its abdominal fat during a routine spay surgery. These growths are rare and are thought to be caused by foreign materials, likely from indigestible plant matter. The dog's health was otherwise good, and the condition was discovered incidentally during surgery. The findings were confirmed through special tests on the tissue samples. This case is notable as it is the first reported instance of this condition in a dog.

Abstract
BACKGROUND: Hyaline ring granuloma (HRG) is an uncommon histopathologic finding of unsolved etiopathogenesis. According to the exogenous theory, HRG develops due to implantation of foreign material, most probably indigestible plant fragments. HRG is a comparatively rare condition in humans, mostly involving the oral cavity with very rare extraoral locations. CASE PRESENTATION: An 1-year-old mixed-breed dog in good condition was presented for routine ovariohysterectomy. Disseminated HGR were accidentally found in the omental adipose tissue during surgery. Histopathology revealed the presence of ring-like hyaline structures surrounded by granulomatous inflammation including foreign body-type multinucleated giant cells. The histochemical examinations indicated the exogenous plant origin of the foreign material. CONCLUSIONS: The lesions were similar to the findings in humans with HRG. The definitive diagnosis remains largely based on histopathological examination supported by special histochemical stains. To the best of our knowledge, this is the first case of hyaline ring granuloma reported in a non-human species. Moreover, the omentum is an uncommon location for this condition.
