[Childhood nasal lymphoma:two cases report and literature review]

Here we report two childhood lymphoma cases,which present with a nasal cavity associated with obstructive symptoms and intermittence pyrexia.Application of antibiotic can temporarily alleviate these symptoms but it can not cure this disease radically.Computed tomography of nasopharynx showed inferior turbinate hypertrophy and absence of obvious specific manifestation.The examination of blood and marrow cells did not find any abnormity.The precision diagnostic evaluation is biopsy of clinically involved mass.The definitive pathological diagnosis is NK/T cell lymphoma.The two younger children patients have shorter course of disease,lacking typical cinical presentation and auxiliary examination of it.We should be vigilant whether a child having nasal obstruction and pyrexia is probably NK/T cell lymphoma or not.
