RESUMEN
Extramedullary plasmacytoma (EMP) and solitary bone plasmacytoma (SBP) represent a disease continuum through a multistage process of cell differentiation, survival, proliferation, and dissemination, strictly related to multiple myeloma (MM), the second most common hematological malignancy. Herein, we report two cases of recurrent oral plasmacytoma progressed to MM, in which the first clinical sign of a more widespread disease was limited to the mouth. Based on our experience, we recommend a strict workup for the differential diagnosis between EMP, SBP, and MM for patients with oral plasmacytoma, including radiological exam of the skeleton, magnetic resonance imaging (MRI) of the bone, and positive emission tomography (FDG-PET). MRI and possibly PET can all be used to more sensitively detect EM plasmacytoma sites.
RESUMEN
PURPOSE: We report on an observational longitudinal noncontrolled study of a case series of consecutive patients treated with zoledronate who underwent tooth extractions. The tooth extractions were performed after a preventive protocol to minimize the risk of bisphosphonate-related osteonecrosis of the jaw. PATIENTS AND METHODS: A total of 43 patients who had received zoledronate and required single or multiple dental extractions were treated. The preventive protocol provided a surgical approach for dental extractions, characterized by the removal of alveolar bone (alveolectomy), and supported by correct antimicrobial therapy (antibiotics and mouthwash). RESULTS: A total of 102 tooth extractions in 43 patients were performed. The follow-up was 12 months. No signs of inflamed tissue or necrotic exposed bone in any patient were observed. CONCLUSIONS: With the limits of the present study, we observed that the removal of the alveolar bone after the tooth extractions and correct antimicrobial prophylaxis (antibiotics and mouthwash) could reduce the risk of occurrence of osteonecrosis in patients taking zoledronate.
