Abstract
Mandible remains a site of swelling for number of diseases including infection, cyst, and tumors. A few rare lesions without any pathognomic and radiological features may cause diagnostic predicament. Diffuse large B-cell lymphoma, a rare form of extranodal non-Hodgkin’s lymphoma accounts for 0.1–0.2% of cases in oral cavity, and occasionally appears in the mandible. We report a case of diffuse large B-cell lymphoma in a 77-year-old male patient. The patient presented with firm, mild painful swelling on the left lower face with history of non-healing extraction socket and enlarged left submandibular lymph nodes leading to a provisional diagnosis of chronic dental infection or dentoalveolar abscess. Incisional biopsy from the lesion and immunohistochemistry study confirmed the diagnosis of diffuse large B-cell lymphoma of left mandible.
