A case of myiasis gingiva was diagnosed in an investigation designed to evaluate the histopathological features of the adjacent tissues of 100 advanced periodontal lesions. The patient was a 36‐year old female and her chief complaint was discomfort and swelling in the area between the upper left central and lateral incisors. The patient's medical history, review of the symptoms, and family history were non‐contributory and her oral hygiene was acceptable. The surgeon was not aware of anything unusual during the operation. Although the Parasitology Department was unable to define the entomologic identification of the infesting parasite from histopathological tissue slides, it was agreed that this case, of myiasis might be produced by larvae of genus Sarcophaga or Enterobius vermicularis.
