Extranodal Nasal-Type Nk/T-Cell Lymphoma With Facial Swelling As The Initial Symptom

Extranodal natural killer (NK)/T-cell lymphoma (ENKTL), nasal type, is an uncommon subtype of non-Hodgkin lymphoma that frequently involves the nasal cavity and nasopharynx. Initially, it can be confused with non-nasal areas, including the skin, gastrointestinal tract, lungs, liver, salivary gland, and testes. The median age at diagnosis of patients with ENKTL is about 50-55 years. This article describes a patient with a single lesion of facial swelling as the first symptom. In cases of ENKTL without a typical clinical course, early histological testing and biopsy could help correct diagnosis.
