Unusual case of hyaline ring granuloma associated with pericoronitis: Case report and review of literature

Abstract

Oral Hyaline Ring Granuloma or Oral Pulse granuloma is a rare entity having unique microscopic features which is often overlooked by clinician as well as pathologist. We assume that there may have been many cases like this in the past which have got unnoticed and unreported. So we felt the urge for contributing this case in the existing literature thus enhancing the knowledge and awareness of health professionals. We have documented a case of 22 year old female patient with pericoronitis related with pain and swelling. On disimpaction, associated pericoronal tissue was removed and sent for histopathological assessment. Microscopically, the lesion resembled structure of processed pulses showing characterstic hyaline rings. The ingested food particles impinge the wound. These food particles act as foreign matter which further induce granulomatous host response.
