  • Title: Intraosseous Non-Hodgkin Lymphoma Mimicking a Periapical Lesion.
    Author: Pereira DL, Fernandes DT, Santos-Silva AR, Vargas PA, de Almeida OP, Lopes MA.
    Journal: J Endod; 2015 Oct; 41(10):1738-42. PubMed ID: 26234541.
    Abstract:
    Non-Hodgkin lymphomas are a group of disorders involving malignant monoclonal proliferation of lymphoid cells, which appear at extranodal sites in approximately 40% of the cases, particularly in the gastrointestinal tract. Intraosseous lymphomas of the head and neck region are extremely rare and can mimic other diseases such as periodontitis or periapical pathologies. This report presents an additional case of intraosseous lymphoma that was previously misdiagnosed as periapical disease. In addition, a literature review was made based on PubMed, and all cases of periapical lymphoma were analyzed. After the diagnosis of lymphoma, the current patient was treated with 6 cycles of chemotherapy and showed satisfactory outcome. The literature review displayed 29 cases of lymphoma affecting the periapical region, and in 51.7% of them endodontic treatment was performed previously to the diagnosis of lymphoma. Although lymphoma is uncommon in the oral cavity, some symptoms can assist the dentist to suspect malignant conditions, mainly in cases presenting numb chin syndrome.
