[A peripheral osteoma].

Abstract

A 43-year-old man appeared with a painless, asymptomatic swelling on the left side of his neck, which had existed for years and had slowly been progressing. After surgical removal, it became clear that it had to do with a peripheral osteoma. This is a benign lesion with a low incidence. Generally, complete surgical removal leads to cure, although recurrence is possible. A peripheral osteoma is mostly located in the mandible, although peripheral osteomata in the frontal or maxillary sinus have been described. The aetiology is unknown. Trauma in the patient's history has been described on occasion. The presence of multiple osteomata in the jawbones is characteristic of Gardner's syndrome.
