Nasal NK/T-cell Lymphoma Presenting as Acute Inflammation of Nasal Vestibule.

Extra nodal nasal NK/T cell lymphoma is relatively a rare type of non-Hodgkin lymphoma. Variable clinical presentation with rapidly progressive necrosis of the cartilaginous and bony wall of the nose and upper respiratory passages leads to delayed diagnosis and treatment. A 43-years-old patient presented with right nasal pain and furuncle-like swelling. The swelling progressed rapidly to cellulitis to the face up to the right eye. Within 2 months, it had advanced to necrosis of the lateral vestibular cartilage, medial maxillary wall, turbinate and nasal septal cartilage. Biopsy reported as non-Hodgkin diffuse T cell (angiocentric T cell) lymphoma.
