Extranodal Nasal NK/T-Cell Lymphoma: A Rare Oral Presentation and FASN, CD44 and GLUT-1 Expression

Abstract: Extranodal natural killer (NK)/T-cell lymphoma is an aggressive malignant tumor with distinctive clinicopathological features, characterized by vascular invasion and destruction, prominent necrosis, cytotoxic lymphocyte phenotype and a strong association with Epstein-Barr virus. Here is reported an extranodal nasal NK/T-cell lymphoma case, involving the maxillary sinus, floor of the orbit, and interestingly extending to the oral cavity through the alveolar bone and buccal mucosa, preserving the palate, leading… Show more

“…Moreover, extranodal NK/T-cell lymphomas and other haematolymphoid processes are also characterized by a vascular infiltrative growth pattern and must also be ruled out. [25][26][27] Therefore, IHC plays an important role in the diagnosis of thalidomide, steroids or hydroxychloroquine, as well as radiotherapy and hematopoietic stem cell transplantation, illustrating the need for individualized therapy depending on the clinical manifestation of each patient. 29 Unfortunately, we were unable to access the treatment approach to our patients, who died due to complications of the disease.…”

“…Geralmente é associado ao EBV, que promove a proliferação celular, além de estar associado a um mau prognóstico. 27,36,38,[71][72] É mais comum na Ásia e nas Américas Central e do Sul, representando 6-7% de todos os LNH. 71 Frequentemente encontrado em asiáticos e populações indígenas.…”

“…27 São encontrados frequentemente em osso alveolar e palato devido à invasão e agressividade e crescimento rápido. 36,[71][72] Suas principais características são invasões e destruição vasculares, acompanhadas de destruição das estruturas da linha média do palato e fossa nasal, levando à formação de uma ulceração necrótica profunda, o que pode causar uma fístula oronasal. 71 As características histológicas são semelhantes, independentemente da localização da neoplasia.…”
