Abstract
Extranodal natural killer/T-cell lymphoma, nasal type (ENKTCL) is a rare Epstein-Barr virus associated lymphoma seen predominantly in Asian population with a 5 years survival rate ranging from 10% to 75% depending on the stage of presentation. In this case report, we describe an unusual presentation of ENKTCL, which in its early stages was clinically misdiagnosed as buccal space infection and later on histologically as inflammatory myofibroblastic pseudotumor owing to manifold reasons. Postoperative biopsy specimen showed characteristic feature of ENKTCL both histologically and immunophenotypically. This case report underlines the importance of adequate sampling and the unusual presentation of ENKTCL nasal type with oral manifestations.
