嗜酸性淋巴肉芽肿的临床特点和治疗

目的分析嗜酸性淋巴肉芽肿的临床病理特点，探讨合理的治疗方案。方法对20例经病理学确诊的嗜酸性淋巴肉芽肿患者的临床特点、治疗方法和预后进行回顾性分析。结果全组20例患者中男性多见，平均发病年龄39岁；临床上表现为单发或多发的结节性肿块，以腮腺区最为多见（41．4％）。所有患者外周血嗜酸性粒细胞均增高。病理学上表现为淋巴组织增生并形成淋巴滤泡，生发中心极性存在，血管周围及滤泡问大量的嗜酸性粒细胞浸润。行单纯手术治疗的3例患者中有2例复发。结论嗜酸性淋巴肉芽肿是一种具有特殊临床和病理表现的慢性炎症性疾病。单纯手术容易复发，手术联合放疗的综合治疗可提高疗效。

Clinical features and treatment of eosinophilic lymphoid granuloma

Objective To explore the clinical features and treatment of eosinophilic lymphoid granuloma.Methods Twenty cases of eosinophilic lymphoid granuloma which were diagnosed by pathology were analyzed retrospectively about their clinical features,treatment and prognosis.Results The average age of the 20 patients was 39 years old,and males were more than females.The specimens presented mainly as a single or multiple nodule,most frequently in parotid gland region.The eosinophilic cells had increased in each case.Histopathological examination revealed lymphoid tissue hyperplasis formation of lymphoid follicles with active germinal centres.There was diffuse infiltration of eosinophils in interfollicular and perivascular zones.2 of 3 patients who selected surgery alone were relapse.Conclusion Eosinophilic lymphoid granuloma is a chronic inflammatory disease which had distinctive clinical and histological features.Surgery alone is easy to relapse,but surgery combined with radiotherapy would improve therapeutic effect.
