Extranodal sinonasal natural killer/T-cell lymphoma presenting as chronic sinusitis and necrotic wound infection.

A case of a 43-year-old white woman who was admitted to our clinic with the complaints of chronic sinusitis and wound infection after Caldwell-Luc operation performed for chronic sinusitis is presented. Necrotic lesion then extended to the nasal cavity and skin of the face. The biopsy revealed natural killer/T-cell lymphoma. The patient was treated with chemotherapy; however, the patient died owing to sepsis. Sinonasal lymphoma is a rare disease. It is managed with chemotherapy and radiotherapy. The prognosis is poor. A high index of clinical suspicion is required for early diagnosis.
