Clinicopathologic studies of 13 cases of chronic eosinophilic leukemia / 中华病理学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the role of bone marrow biopsy (BMB) in diagnosis and differential diagnosis for chronic eosinophilic leukemia (CEL).</p><p><b>METHODS</b>Clinical and pathological features of thirteen CEL patients were analyzed retrospective. Routine histologic examination was performed on H-G-E, reticulin fiber and toluidine blue stained sections of plastic material emdedded samples of bone marrow biopsies.</p><p><b>RESULTS</b>(1)The male-to-female ratio was 121. The median age was 40 (23-67) years old. They presented as fever, anemia, hemorrhage and so on. Most of organs and tissues were also be involved. (2) Peripheral blood counts characterized by eosinophilia (18.1 +/-16.2) x 10(9)/L, (3) BMB showed eosinophils were predominant components, others such as neutrophils, erythrocytes, megakaryocytes were decrease. Degree of reticular fiber was from (1+) to (3+). (4) Follow-up information was available in only 4 patients, whose conditions were stable.</p><p><b>CONCLUSION</b>Combine with the clinical manifestations of CEL patients, it is important in diagnosis and differential diagnosis for CEL by observing the histomorphology features of bone marrow biopsy carefully.</p>
