OCHOA-ARIZA, María Fernanda et al. EXTRANODAL NK/T-CELL LYMPHOMA, NASAL TYPE: CASE REPORT. Case reports [online]. 2021, vol.7, n.1, pp.7-14. Epub 04-Jun-2021. ISSN 2462-8522. https://doi.org/10.15446/cr.v7n1.85915.
Introduction:
Extranodal NK/T-cell lymphoma, nasal type (ENKL), is a highly aggressive non-Hodgkin's lymphoma of unknown etiology. Clinical manifestations are usually nasal obstruction, epistaxis, and inflammatory signs. Diagnosis can be difficult to achieve and requires histo-pathology and immunohistochemistry studies. Radiotherapy and chemotherapy have been proposed as treatment, depending on the stage of the disease.
Case presentation:
A 44-year-old male patient, previously healthy, attended the outpatient service due to clinical nasal obstruction, secretion, edema, and facial erythema for 2 months. Facial cellulitis was initially diagnosed, but since there was no improvement with antibiotic treatment, the patient was referred to the emergency department of a higher complexity center, where complementary imaging showed a mass in the right nasal cavity. A histopathological analysis established that it was an ENKL, so radiotherapy was indicated; however, as a result of the advanced stage of this neoplasm, the patient died.
Conclusion:
Timely diagnosis of ENKL is crucial to improve life expectancy. Nevertheless, it may represent a clinical challenge due to its nonspecific presentation.
