二、发病情况
➢ 年发病率2.76/10万; ➢ 儿童及35岁以下成人中恶性肿瘤死亡率第一位; ➢ 我国急性白血病:慢性=5.5:1,AML>ALL,儿童ALL多见。慢
性白血病中CML>CLL; ➢ 男性>女性;
三、病因和发病机制
不完全清楚,但不是单一因素引起 ➢ 生物因素 ➢ 物理因素:电离辐射 ➢ 化学因素 ➢ 遗传因素 ➢ 其它血液病:慢粒、真红、骨纤、MDS等

Clinical findings
ØInfection Infection is due to neutropenia.
gram-negative bacteria or fungi.
Common presentations include cellulitis, pneumonia, and perirectal infections. Septicemia in severely neutropenic patients can cause death within a few hours if treatment with appropriate antibiotics is delayed.
Bleeding occurs in the skin and mucosal surfaces, with gingival bleeding, epistaxis, or menorrhagia. Less commonly, widespread bleeding is seen in patients with disseminated intravascular coagulation.

一、概念
是一类起源于造血干细胞的恶性疾病。其克隆中的白 血病细胞失去了进一步分化成熟能力而停滞在细胞发育的 不同阶段,使造血组织中白血病细胞大量增殖,伴其他器 官和组织的广泛浸润,导致正常造血受抑。

分子生物学 (Molecular biology)
AML1/ETO、PML/RAR、
Granulocytic sarcoma is a tumor composed of myeloblasts or monoblasts. These tumors may be found in any location, especially the skin, gum, orbit, genitourinary tract(especially testis),central or peripheral nervous system. These tumors were originally called chloromas because of the green color imparted by the heavy concentration of the enzyme myeloperoxidase present in leukemic cells.
skin and gum:M4, M5
orbit: M3
(4) Central nervous system leukemia: ALL, M4, M5, M2
(5) Testis hypertrophy: ALL
