Extranodal T/NK-Cell Lymphoma is a form of non-Hodgkin lymphoma (NHL) which are most of B-cell origin.
What is the Pathology of Extranodal T/NK-Cell Lymphoma?
The pathology of extranodal T/NK-Cell lymphoma is:
-Etiology: The cause of extranodal T/NK-Cell lymphoma is as follow: Acquired immunodeficiency ailments, Inherited immunodeficiencies, autoimmune ailment, association with infectious agents (EBV), and chemical or drug exposures (radiation).
-Genes involved: Unknown.
-Pathogenesis: The sequence of events that lead to extranodal T/NK-Cell lymphoma; Nasal NKTCLs are mostly linked with Epstein-Barr virus (EBV), regardless of the background of the affected population. The precise mechanism of malignant conversion via EBV is not yet clearly clarified.
-Histology: The histology associated with extranodal T/NK-Cell lymphoma shows the presence of a broad cytologic spectrum. Diffuse infiltration of both pleomorphic small and large lymphoma cells, assorted with several inflammatory cells on the necrotic contextual. Cells are with, small nucleoli, pale-to-clear cytoplasm, granular chromatin, and irregular nuclei.
How does Extranodal T/NK-Cell Lymphoma Present?
Patients with extranodal T/NK-Cell lymphoma typically male are more frequently affected with the ailment than females, with a ratio of 3:1. present at age range of the sixth decade. The symptoms, features, and clinical findings associated with extranodal T/NK-Cell lymphoma include: night sweats, weight loss, bone pain, fever, fatigue, facial agony, decreased visual acuity, purulent nasal discharge, orbital swelling, nasal obstruction, refractory sinusitis, nasal septal perforation among others.

Imaging studies include CT scan and MRI other include nasopharyngoscopy and biopsy.
How is Extranodal T/NK-Cell Lymphoma Treated?
Extranodal T/NK-cell lymphoma is treated Medical care chemotherapy based on tumor cell growth; Antineoplastic agents, Vincristine, Doxorubicin Cyclophosphamide, and Prednisone. Surgical intervention is limited to biopsy, debulking of disease, and the need to stabilization the airway.
What is the Prognosis of Extranodal T/NK-Cell Lymphoma?
The prognosis of extranodal T/NK-cell lymphoma is poor. Multidrug resistance phenotype contributes to low survival rates, low rates of rejoinder to management are secondary to CD56 cell marker.
