Prognostic factors for mature natural killer (NK) cell neoplasms: aggressive NK cell leukemia and extranodal NK cell lymphoma, nasal type.
BACKGROUND Patients with natural killer (NK) cell neoplasms, aggressive NK cell leukemia (ANKL) and extranodal NK cell lymphoma, nasal type (ENKL), have poor outcome. Both diseases show a spectrum and the boundary of them remains unclear. The purpose of this study is to draw a prognostic model of total NK cell neoplasms. PATIENTS AND METHODS We retrospectively analyzed 172 patients (22 with A...
متن کاملAggressive natural killer cell leukemia or extranodal NK/T cell lymphoma? a case with nasal involvement
BACKGROUND Aggressive natural killer cell leukemia/lymphoma (ANKL) is a rare and highly aggressive NK cell neoplasm with a short clinical course and poor prognosis and is often misdiagnosed and confused with NK/T cell lymphoma (NKTL), which has a very different prognosis. Here, we present a case with nasal and bone marrow involvement, provide a literature review and make a differential diagnosi...
متن کاملAggressive natural killer cell leukemia in an adult with establishment of an NK cell line.
There have been many reports of cases in which chronic increases in the numbers of natural killer (NK) cells have been reported. Whether this is reactive or neoplastic in nature has been debated. We report the first case of an aggressive NK cell leukemia in an adult with establishment of an NK cell line. A 70-year-old man had two spontaneous episodes of jejunal perforation and one month later d...
متن کاملThe diagnosis and management of extranodal NK/T-cell lymphoma, nasal-type and aggressive NK-cell leukemia.
Natural killer (NK) cell lymphomas are rare malignancies. They are classified as extranodal NK/T-cell lymphoma, nasal type, and aggressive NK cell leukemia. NK cell neoplasms are prevalent in Asian and South American populations, but are extremely rare in the West. They can be classified clinically into nasal, non-nasal, and aggressive lymphoma/leukemia subtypes. For nasal NK cell lymphomas, co...
متن کاملBlastic NK-Cell Leukemia / Lymphoma
Blastic natural killer (NK) cell lymphoma / leukemia is a rare NK cell malignancy of unknown etiology. It occurs in multiple sites and with a propensity for skin involvement. We report such a case in a 35-year-old male suffering from erythematous and purpuric papules and plaques on his face and trunk for 6 months. A biopsy specimen of the skin showed diffuse infiltration of blastlike lymphoid c...
