Surgical excision of peripheral giant cell granuloma of the maxilla: a case report

Peripheral giant cell granuloma (PGCG) is described as an elevated lesion that is located mostly on the gingival mucosa and alveolar crest, consecutive to irritative factors and trauma. It predominantely occurs more in the mandible than the maxilla, and it is usually seen in the 4th to the 6th decades. The clinical appearance of this lesion is red bluish in color, presenting a similar tissue to the one observed in the liver, usually measuring less than 2 cm. The treatment of the PGCG is the surgical excision. The recurrence of this lesion is rarely described in the literature. The present case highlights the importance of considering the traumatic extractions as one of the main uncommon etiologic factors, leading to the development of peripheral giant cell granuloma. It precisely describes the diagnosis, the treatment of a peripheral giant cell granuloma located in maxillary canine-premolar region, occurred consecutively after ancient traumatic extractions of the 13 and 14 since 1 year. This paper also reports a maxillary location of giant cell granuloma, while the literature reports more commonly the mandibular location. This lesion was excised surgically, and healed uneventually and in which the follow-up didn ' t show any sign of recurrence.
