BackgroundHyaline 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 presentationAn 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.ConclusionsThe 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.

Oral pulse granuloma (PG) is a rare lesion that presents as a foreign body granulomatous reaction to implanted food particles of plant or vegetable origin. It is classified as a central or a peripheral lesion depending on the location. Rarely, a central oral PG may be associated with a cyst or tumor, thus leading to a deceptive histopathological picture. This is exemplified in the present case of 27-year-old female patient who reported with a swelling on the left posterior region of mandible which was diagnosed as ameloblastoma. The excisional specimen depicted a varied histopathological picture showing follicular ameloblastoma and foreign body granulomas associated with hyaline rings. Based on histopathological, histochemical and polarized microscopy findings; these hyaline rings were diagnosed to be remnants of a plant cell/legume. The aim of this article was to present a case of PG associated with ameloblastoma and discuss its histochemical and polarizing microscopic features.

“…Occasionally, the lesions occur in the wall of the cyst, most common being inflammatory odontogenic cyst. [ 3 ] However, a similar condition described as PG is usually observed in lungs and alimentary tract, usually in infants and severely debilitated persons. [ 2 4 ]…”

“…Histologically, they appear as eosinophilic hyaline mass with giant cell inclusions and inflammatory cells. [ 3 ] The granulomas may assume different histologic characteristics, possibly related to the length of time in the tissue (evolution) and location. Adequate recognition is important to avoid misdiagnosis.…”

Pulse or hyaline ring granulomas are rare but are well-defined oral and extraoral lesions due to implantation of the cellulose moiety of plant foods in contrast starch components. A unique form as reactive gingival growth showing histologic features of oral pulse or hyaline ring granuloma (OPHRG) which had resulted from implantation of food particles of plant or vegetable origin into the periodontium has been illustrated. Such a presentation is attributable to compromised periodontal health and poor oral hygiene favoring the implantation of food particles has been described here along with a literature update on OPHRG.
