Non-Hodgkins lymphoma - A case report and review of literature

Lymphomas are solid tumors of the immune system and include 14% of all head and neck malignancies. Non-Hodgkin lymphomas (NHLs) are a heterogeneous group of lymphoproliferative disorders originating in B-, T-, or natural killer T-cells. They have a wide range of histological appearances and clinical features at presentation, which can make diagnosis difficult. A 58-year-old male patient presented with a 1-month history of swelling in the upper right back tooth region, which developed after extraction. On intraoral examination, there was small nodular lesion proliferation from the extracted socket. Biopsy specimen on histological examination revealed sheets of small round cells with hyperchromatic nucleus resembling lymphoblast. Immunohistochemistry (IHC) confirms the NHL of T-cell origin. This article is an attempt to correlate the clinical presentation and histological importance of small round cell tumors of the jaw and to discuss the differential diagnosis of small round cell tumors. Typically, a multimodal approach is employed, and the principal ancillary technique that have been found to be useful in classification is IHC.
