Extranodal (Nasal Variant) NK/T ‐Cell Lymphoma of Head and Neck: Our Experience From a Tertiary Care Centre

Key Points

• To provide insights into extranodal NK/T-cell lymphoma (ENNK) presentations and emphasize its recognition among chronic sinusitis cases.
• Descriptive cohort analysis of ENNK cases at a tertiary care center
• Examination of patient referrals initially diagnosed with chronic sinusitis or granulomatous disease
• Review of clinical manifestations and diagnostic challenges encountered
• Identification of ENNK in patients previously misdiagnosed with chronic sinusitis
• Highlighting the need for ENNK inclusion in differential diagnoses by otorhinolaryngologists
• Improved early detection strategies leading to potentially better patient outcomes
