摘要:

目的探讨外周血淋巴细胞免疫表型分析在皮肤T细胞淋巴瘤中的应用价值。方法采用流式细胞术检测52例确诊皮肤疾病患者[包括31例皮肤T细胞淋巴瘤(恶性皮肤病组)、21例炎症性皮肤病(良性皮肤病组)]外周血淋巴细胞免疫表型并进行形态学检查。比较良性和恶性皮肤病淋巴细胞亚群、免疫表型特点及其外周血形态学特点。结果恶性皮肤病组CD4/CD8 双阴性T淋巴细胞明显高于良性皮肤病组(P<0.05),而恶性皮肤病组B淋巴细胞百分比明显低于良性皮肤病组(P<0.05)。恶性皮肤病组中Sézary综合征亚组T淋巴细胞百分比、CD4/CD8比值以及CD4/CD8 双阴性T淋巴细胞百分比高于其他恶性皮肤病亚组以及良性皮肤病组(P<0.05),B淋巴细胞和自然杀伤(NK)细胞百分比降低(P<0.05)。恶性皮肤病组中有14例(45.1%)免疫表型异常,有15例(48.4%)外周血淋巴细胞形态异常;良性皮肤病组中有5例(23.8%)免疫表型异常,有6例(28.6%)外周血淋巴细胞形态异常。结论外周血淋巴细胞免疫表型分析可为皮肤T细胞淋巴瘤的临床诊断提供佐证,有助其鉴别诊断。

Abstract:

Objective To investigate the application significance of peripheral blood lymphocyte immunophenotype in cutaneous T-cell lymphoma. Methods Peripheral blood lymphocyte immunophenotype was analyzed by flow cytometry and morphology in 52 patients diagnosed as skin disorders [31 cases of cutaneous T-cell lymphoma(malignant skin disorder group)and 21 cases of inflammatory skin disorders(benign skin disorder group)]. The characteristics of lymphocyte subset,immunophenotype and morphology between benign and malignant skin disorder groups were compared. Results CD4/CD8 double negative T lymphocyte in malignant group was significantly higher than that in benign group (P < 0.05),and B lymphocyte percentage in malignant group was significantly lower than that in benign group (P < 0.05). In malignant group,T lymphocyte percentage,CD4/CD8 ratio and CD4/CD8 double negative T lymphocyte percentage in Sézary syndrome subgroup were higher than those in benign group and other malignant skin disorder subgroups (P < 0.05),meanwhile B lymphocyte and natural killer(NK) cell percentage decreased (P < 0.05). There were 14 abnormal cases of malignant group(45.1%) and 5 abnormal cases of benign group(23.8%) for immunophenotype. There were 15 abnormal cases of malignant group(48.4%) and 6 abnormal cases of benign group(28.6%)for morphology. Conclusions Peripheral blood lymphocyte immunophenotype can provide a reference for the diagnosis of cutaneous T-cell lymphoma,and it is helpful with the differential diagnosis.
