遗传性椭圆形红细胞增多症,有人称其为卵形红细胞增多症。现代医学已证明该病系一常染色体显性遗传性疾病,两性均可罹病。是为红细胞膜缺陷所致溶血性贫血的一种,其特点及发病机理酷似遗传性球形红细胞增多症。其红细胞形态的变化被视做是一种返祖现象。一般的正常人也可以在末梢血中查到1～15%的椭圆形红细胞,而本病常见到25～50%之多,乃至高达90%,如果这种红细胞>25～50%即有诊断价值。如>75%可肯定诊断。通过对患者染色体的检查证实本病多数属杂合子,少数为纯合子。两者患病的临床表 Hereditary oval polycythemia, some people call it oval polycythemia. Modern medicine has proved that the disease is an autosomal dominant genetic disease, both sex can be sick. Is a red cell membrane defects due to hemolytic anemia, its characteristics and pathogenesis resembles hereditary spherocytosis. The change of erythrocyte morphology is regarded as an ancestor phenomenon. Normal normal people can also be found in the peripheral blood of 1 to 15% of oval red blood cells, while the disease often seen as 25 to 50%, or even up to 90%, if the red blood cells> 25 to 50% of the diagnosis value. Such as> 75% can confirm the diagnosis. Through the examination of the patient’s chromosome confirmed that most of the disease is a heterozygote, a few homozygotes. Both are sick clinical tables
