Abstract

Purpose To describe new cases of primary malignancy arising around dental implants. Materials and Methods Three patients presented with asymptomatic lesions around longstanding dental implants that resembled peri-implantitis. One case was primary large B-cell lymphoma and the remaining cases were primary squamous cell carcinoma in patients with oral lichen planus. The literature was reviewed for cases mimicking peri-implantitis. Results Of 42 implant-associated malignancies reported from 2000 through 2014, 85.7% were squamous cell carcinoma (69% primary and 9.4% metastatic). Most patients presented with pre-existing risk factors for oral cancer. Lymphoma was not associated with dental implants. Conclusions Primary and metastatic malignancies can occur in peri-implant mucosa, often with clinical and radiographic features resembling peri-implantitis. Clinicians should have a high index of suspicion for changes in peri-implant mucosa in patients with existing risk factors; however, rare cases such as lymphoma might present outside this risk population. Histopathologic analysis should be included in the management of selected peri-implant lesions to avoid delayed diagnosis of malignancy.
