Abstract
Purpose. Implant therapy plays an important role in contemporary dentistry with high rates of long-term success. However, in recent years, the incidence of peri-implantitis and implant failures has significantly increased. The peripheral giant cell granuloma (PGCG) rarely occurs in peri-implant tissues and it is clinically comparable to the lesions associated with natural teeth. Therefore, the study of possible diseases associated with dental implants plays an important role in order to be able to diagnose and treat these conditions. Materials and Methods. This report described a 60-year-old Caucasian male who presented a reddish-purple pedunculated mass, of about 2 cm in diameter, associated with a dental implant and the adjacent natural tooth. Results. An excisional biopsy was performed and the dental implant was not removed. Histological examination provided the diagnosis of PGCG. After 19-month follow-up, there were no signs of recurrence of peri-implantitis around the implant. Conclusion. The correct diagnosis and appropriate surgical treatment of peri-implant giant cell granuloma are very important for a proper management of the lesion in order to preserve the implant prosthetic rehabilitation and prevent recurrences.
Highlights
Peripheral giant cell granuloma (PGCG) is an exophytic lesion of the gingiva, arising from the periosteum or from the periodontal membrane in response to local irritating factors or a chronic trauma [1,2,3]

Summary
Peripheral giant cell granuloma (PGCG) is an exophytic lesion of the gingiva, arising from the periosteum or from the periodontal membrane in response to local irritating factors or a chronic trauma [1,2,3]. It clinically appears as a reddishpurple sessile or pedunculated mass with soft consistency and smooth or ulcerated surface. PGCG mainly affects female patients (60% of cases) and, it can occur at any age, has a peak incidence between 40 and 60 years [3, 4]. There may be bone resorption in the area of the lesion or involvement of the supporting tissues of the adjacent teeth which appears on the radiography as a flare of the periodontal ligament [2, 3, 7]
