成人非淋巴细胞白血病的白血病前期(白前)状态已被广泛地认识。儿童非淋巴细胞白血病的白前状态也已识别,但儿童中最常见的急淋(ALL)的白前状态尚罕见报告。本文报告2例,并复习文献中的13例。例1为18个月女孩,出现发热和中耳炎。体检未见器官肿大。血常规检查:血红蛋白10.1g;白细胞5,400,或熟淋巴细胞占95%。未见有核红细胞。网织红细胞计数为0。血小板270,000,红细胞平均容积为92。在3个不同部位作4次骨髓穿刺活检,示细胞
The status of pre-leukemia of adult non-lymphocytic leukemia has been widely recognized. The pre-white status of childhood non-lymphocytic leukemia has also been identified, but the prevalent status of the most common acute leukemia (ALL) in children is rarely reported. This article reports 2 cases and reviews 13 cases in the literature. Example 1 for 18-month-old girl, fever and otitis media. No organ enlargement examination. Blood tests: hemoglobin 10.1g; white blood cells 5,400, or mature lymphocytes accounted for 95%. No visible red blood cells. Reticulocyte count was 0. Platelets 270,000, the average volume of red blood cells 92. Four bone marrow biopsies were performed at three different sites to show the cells
