Abstract

Extranodal NK/T cell lymphoma, 'nasal type,' is a rare clinicopathological entity in Europe. The main clinical features are nasal congestion, sore throat, dysphagia and epistaxis, due to a destructive mass involving the midline facial tissues. Pathologically, lymphoma cells exhibit angioinvasion, angiodestruction and coagulative necrosis. We report the case of a patient who presented with fever, dyspnea, nasal congestion, headache, distention of right nasal turbinates and exophytic lower leg ulcerating lesions. A CT scan of visceral scull demonstrated a filling mass of right frontal, ethmoidal and maxillary sinuses with erosion of the wall of right maxillary sinus and ventral portion of the diaphragm. A biopsy was performed in the skin lesion and showed an angioinvasive NK/T cell lymphoma CD56 negative with clonal rearrangement of the T-cell-receptor gamma gene. Up to our knowledge, this is a rare immunophenotype for NK/T-cell, 'nasal type,' lymphomas. However, the lymphoma may be classified as extranodal NK/T cell lymphoma, 'nasal type,' due to typical clinical presentation, radiologic findings and pathological characteristics of polymorphism, angioinvasion, angiodestruction and coagulative necrosis.
