Overview
Natural History
- Extranodal NK-T cell lymphoma almost always shows an extranodal presentation.[1]
- Some cases may be accompanied by secondary lymph node involvement although rare instances of primary lymph node disease in the absence of extranodal involvement has been reported.
- Extension to adjacent tissues such as the nasopharynx, paranasal sinuses, orbit, oral cavity, palate, and oropharynx are possible.
- At presentation, the disease is often localized to the upper aerodigestive tract.
- Disseminated disease may have involvement of the lymph nodes, bone marrow and peripheral blood.
Complications
Extranodal NK/T-cell lymphoma, nasal type, often develop hemophagocytic syndrome (uncontrolled activation of certain parts of the immune system)[2]
This condition results in
- Fever
- Hepatosplenomegaly
- Pancytopenia
