Abstract:
Nasal NK/T cell lymphomas are aggressive, locally destructive, midfacial, necrotizing lesions. The nonspecific clinical symptoms constitute a major stumbling block in the early diagnosis and management of these lymphomas. We report here a case of probable nasal NK/T cell lymphoma in an apparently healthy male that progressed rapidly in a short span of time and was managed subsequently with chemotherapy and external beam irradiation with which the lesion regressed.

Cells of the Innate Immune Response
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
