Primary bone NK/T cell lymphoma is very rare. We report a case of 52-year-old man of primary bone NK/T cell lymphoma and then progressed to NK leukemia. The patient had low-grade fever for 4-month, and Ultrasonic B revealed a diffuse hepatosplenomegaly without lymphadenopathy. PET scanning showed increased FDG uptake in many bones of the whole body. The diagnosis was established by bone specimen. These neoplastic cells demonstrated a typical immunophenotype of CD56, CD3, CD2 and MPO positive, and CD5, CD20, CD30, PAX-5, CD4 and CD8 negative. Primary bone ENKTL is very rare; it should be made with the combination of clinical feature, PET-CT image, and pathological characteristics, and should be distinguished from other lymphomas or leukemia involved in bone.
原发性骨NK/T细胞淋巴瘤非常罕见。我们报告一例52岁男性原发性骨NK/T细胞淋巴瘤,随后进展为NK白血病。患者低热4个月,超声B显示弥漫性肝脾肿大,无淋巴结肿大。PET扫描显示全身多处骨骼FDG摄取增加。通过骨标本确诊。这些肿瘤细胞表现出典型的免疫表型,CD56、CD3、CD2和MPO阳性,CD5、CD20、CD30、PAX-5、CD4和CD8阴性。原发性骨ENKTL非常罕见;应结合临床特征、PET-CT图像和病理特征进行诊断,并应与累及骨骼的其他淋巴瘤或白血病相鉴别。
