Although gingival reactive lesions such as pyogenic granulomas (PG) are fairly common in gingiva with natural teeth, their occurrence in association with dental implants is relatively rare. Additionally, these lesions are relatively small in size (10 mm). This case report presents a large PG observed in association with a dental implant and a systematic review of the literature on implant-associated PG. A 66-year-old woman presented at our department with a smooth, slightly red pedunculated lesion measuring 45 mm × 40 mm × 20 mm on the buccal and lingual gingiva surrounding the left mandibular second molar dental implant. Horizontal alveolar bone loss around the dental implant was observed on panoramic radiographs and cone-beam computed tomography. A biopsy was performed, and a histopathological diagnosis of PG was made. Complete resection of the lesion and curettage of the implant surface under local anesthesia was carried out. The patient exhibited no recurrence of PG after one year of follow-up.
