Peripheral Giant Cell Granuloma in the Maxilla: A Case Report Ahmet Şanlıdağ1, Taner Arabacı1, Çiğdem Yıldırım1 1 Atatürk University Faculty of Dentistry Peripheral giant cell granuloma is a common benign lesion in the oral cavity and more common in women. That is etiology occurs due to periosteum, periodontal membrane or irritant factors. Chronic irritant factors, namely microbial biofilm, are thought to be the secondary reaction of calculus, incompatible fillings and prostheses. Peripheral giant cell granuloma can be seen in the alveolar or gingival mucosa, with or without sessile. A 29-year-old female patient applied to our clinic with gingival swelling, bleeding and aesthetic complaints in the maxillary anterior vestibule region. In the anamnesis taken from the patient, it was learned that the patient was 8 weeks pregnant. Oral hygiene education was given to the patient as an initial treatment. At the patient's request, the treatment was performed after parturition. In order to make the differential diagnosis, the lesion was taken in the form of a ring by excisional biopsy under local anesthesia. As a result of the pathology evaluation, the lesion was diagnosed as peripheral giant cell granuloma. No recurrence was observed in the 6-month follow-up of the patient.
