BACKGROUND: Angiocentric centrofacial lymphomas, now known as nasal-type extranodal natural killer T-cell lymphomas, are neoplasms of highly destructive characteristics that mainly affect the nasal cavity and palate. The most frequent clinical presentation includes fever, weight loss, nasal obstruction, epistaxis, nasal or facial edema, as well as necrotic ulcers in the nasal cavity, gums, and palate. It has been found to have an important association with the Epstein-Barr virus. Diagnostic pathology could be difficult due to the typical widespread tissue necrosis.

CASE REPORT: A 72-year-old Caucasian male sought medical attention with a chief complaint of nasal obstruction for the past 3 years, which only responded partially to unspecific treatment. He also presented with intermittent fever and nocturnal hyperhidrosis. Physical examination with rhinoscopy demonstrated a deviated septum, congestive turbines, and fragile and pale mucous membrane with yellowish, thick mucus. The pathology report described an angiocentric centrofacial lymphoma and a positive serology for Epstein-Barr virus.

CONCLUSIONS: The objective of this case report was to show that this illness represents a diagnostic challenge for the treating physician. It may be concluded that despite the poor prognosis of the disease, this particular case showed slower evolution and the patient remained stable despite multiple consecutive complications.
