Extranodal natural killer/T-cell lymphoma nasal type.

Extranodal natural killer/T-cell lymphoma nasal type (ENKL) is a rare neoplasm uncommon in the US. Diagnosis is complicated by low incidence and rapid tissue necrosis preventing timely histologic confirmation. We report the case of a 55-year-old woman with ENKL who faced a challenging diagnostic workup due to widespread nasal tissue necrosis and nonspecific sinus-related complaints. While ENKL is significantly more common in Asia and South America, clinicians worldwide should maintain a high level of suspicion for patients presenting with nonspecific nasopharyngeal complaints who have signs of tissue necrosis. Early recognition and treatment with combined radiotherapy and chemotherapy can improve survival.
