本文报道７例毛细胞白血病瘤细胞的超微结构，并与慢性淋巴细胞白血病（４例）做了比较。结果表明，毛细胞白血病依其淋巴细胞表面突起的不同，分二型：微绒毛型，突起直径０．１μｍ，长约０．７μｍ；毛发分枝型，突起长达１．５～３μｍ，且有分枝。讨论了电镜在毛细胞白血病鉴别诊断中的作用。
This article reports the ultrastructure of 7 cases of hairy cell leukemia cells and compares them with chronic lymphocytic leukemia (4 cases). The results showed that hairy cell leukemia is divided into two types: microvilli type, with a protrusion diameter of 0.1 μm and a length of about 0.7 μm depending on the protrusion of lymphocytes, and a branching type of hair with a protrusion of 1.5 to 3 μm. There are branches. The role of electron microscopy in the differential diagnosis of hairy cell leukemia was discussed.
