Extranodal NK/T-cell lymphoma, nasal type is
an aggressive lymphoma that is very rare but more common in Asian and
Hispanic communities. It can involve the nasal area, the trachea, the
gastrointestinal tract, or skin.
"Normal Natural Killer cells are a certain type of white blood cell that attacks tumour cells and infected body cells by binding to a tumour cell and releasing lethal chemicals. Natural killer cells are thought to play a key role in cancer prevention by killing abnormal cells before they multiply and grow."
"Because NK-cell lymphomas express some T-cell
markers, they may be mistakenly diagnosed as peripheral T-cell
lymphomas if they are not investigated for the NK-cell-specific
marker, CD56. Therefore the importance of immunophenotypic
investigations of CD56 should be stressed. Also, the importance of
clinical investigation of nasal/nasopharyngeal lymphomas should be
stressed when NK-cell lymphoma is diagnosed involving the skin,
because NK-cell lymphomas are often associated with the nasal and
nasopharyngeal region."

Case report: Regression of the tumor after withdrawal of cyclosporine in relapsed extranodal natural killer/T cell lymphoma following allogeneic hematopoietic stem cell transplantation
A 43-year-old female underwent allogeneic HSCT for
advanced-stage, chemorefractory ENKL, and achieved complete
response. In 4 months after the transplantation, however, the ENKL
relapsed in multiple sites. These lesions markedly responded to
the discontinuation of immunosuppressive agents and disappeared.
Except for a temporal exacerbation of bronchiolitis obliterans
organizing pneumonia, she has been free from disease for more than
a year without other treatments against lymphoma. The clinical
course of the current patient suggests the potent GVL effect
showed favorable outcome in treating early stage extranodal
nasal-type NK/T-cell lymphoma in children and adolescents.
