A 57-year-old woman was referred from her hematologist for evaluation of a left mandibular gingival swelling of 1 week’s duration. The hematologist expressed concern about odontogenic infection owing to the patient’s prolonged immunosuppressive chemotherapy for the management of treatment-resistant multiple myeloma (MM). The diagnosis of MM had been made in 2017, and since then she had received multiple rounds of chemotherapy, undergone autologous stem cell transplantation, and received intravenous zoledronic acid (Zometa; Novartis).
