伴嗜酸性粒细胞增多性血管淋巴样增生的临床病理分析

目的：探讨伴嗜酸性粒细胞增多性血管淋巴样增生的临床病理学特征。方法：对我科1950-1999年期间所诊治的伴嗜酸性粒细胞增多性血管淋巴样增生的7名患者的病理标本重新切片，进行病理学上的分析。结果：伴嗜酸性粒细胞增多性血管淋巴样增生在病理学上有其特征，形态学上的改变主要表现在以下3个方面：①真皮内大量毛细血管增生；②血管内皮细胞增生肿大，似“墓碑”状突入血管腔；③病变处有淋巴细胞、嗜酸性粒细胞混合浸润。结论：伴嗜酸性粒细胞增多性血管淋巴样增生是一种良性局限性血管增生，其病因及发病机制尚不清楚。熟悉这一疾病的组织学改变对避免误诊为其他类拟疾病有重要意义。

Clinicopathological analysis on angiolymphoid hyperplasia with eosinophilia

Objective　To analyze the clinicopathological features of angiolymphoid hyperplasia with eosinophilia (ALHE). Methods　The pathological specimens of 7 cases of ALHE collected in our department from 1950 to 1999 were sectioned, stained and observed. Results　There were 3 pathological characteristics in ALHE: ①massive hyperplasia of capillaries in the dermis; ②the endothelial cells proliferated and swelled, projecting into vascular cavity like tombstones; ③mixed infiltration of lymphocytes and eosinocytes in the vessels. Conclusion　ALHE is a disease with local benign proliferated vessels, whose etiology and pathogenesis is still unknown. It is necessary to grasp the pathological changes of ALHE to distinguish it from other diseases.
