TUMORS, LYMPHOMA, NHL
Tumors in the area of the head and neck can be easily noticed and accessed, but the clinical behavior and manifestations of NHL usually lack specific characteristics without biopsy and histological evidence. Hence, the diagnosis of NHL should be taken into consideration by physicians in cases of unknown cervical or oral masses. H&NNHL is a lymphoproliferative malignancy, due to the great heterogeneity and inconsistency, treatment options and survival outcomes varied from patient to patient. Some researchers have reported prognostic factors of lymphoma in some local regions, such as the tongue, thyroid, laryngeal, and sinonasal.
