Benign ethnic neutropenia (BEN) is an asymptomatic condition reported in adults of African and Middle Eastern descent. The clinical description in children is currently lacking. In our urban outpatient pediatric hematology clinic, the median neutrophil count of children with BEN was lower than previous reports in adults at 893×10 cells/L, but increased with older age. There was an equal male to female ratio and 24% of our BEN children reported ethnicities other than African or Middle Eastern. Children with BEN had a clinical course comparable with other healthy children including otherwise normal blood counts, except for mild anemia.
良性种族性中性粒细胞减少症(BEN)是一种在非洲和中东血统成年人中报告的无症状病症。目前缺乏关于儿童的临床描述。在我们城市的儿科血液科门诊中,BEN儿童的中性粒细胞计数中位数低于先前关于成年人的报告,为893×10⁹/L,但随着年龄增长而增加。男女比例相等,我们的BEN儿童中有24%报告的种族不是非洲或中东种族。BEN儿童的临床病程与其他健康儿童相当,包括血常规检查正常,仅有轻度贫血除外。
