Nasal NK/T-cell lymphoma in the paediatric population. Two case reports.
Nasal natural killer (NK)/T-cell lymphoma is an uncommon disease, and only a few paediatric cases are found in the literature. We report 2 cases of NK/T-cell lymphoma occurring in children. The primary site was the the nasal cavity in the first case (5-year-old girl) and the tonsil in the second case (4-year-old boy). Histological study showed a polymorphic neoplastic infiltrate with an angioinvasive pattern and T-cell phenotype. Ebstein-barr virus infection was established by in situ hybridization. Both underwent an aggressive chemotherapy regimen. The outcome was favorable for the 4-year old boy; however, the 5-year-old girl died two months after diagnosis.
