Extra-nodal Diffuse Large B-cell Lymphoma (Germinal Center Type) Manifesting as Non-healing Extraction Socket

Manasa Syamala et al. J Clin Diagn Res. 2016 Aug.

Abstract

Lymphomas occurring in the oral cavity are rare. They account only for about 2% of extra-nodal sites. Most of the lymphomas occur in the lymph nodes and in the oral cavity, the most commonly affected region is the Waldeyer's ring. Its occurrence in the mandibular gingiva is rare. Here, we describe a case of Diffuse Large B-cell Lymphoma manifested as a non-healing extraction socket in the mandibular right posterior region in a 62-year-old male patient.

Keywords: Diabetic; Lymph nodes; Lymphadenitis; Sialadenitis.
