摘要
目的探讨蠕形螨病的皮肤组织病理学变化。方法取蠕形螨感染者患处组织,石蜡包埋切片,HE染色,镜下病理学观察。结果蠕形螨寄生于毛囊和皮脂腺内,使毛囊不规则扩张,皮脂腺增生肥大,虫体周围有炎症细胞浸润。结论面部毛囊扩大,皮脂腺增生及其炎症反应与蠕形螨的寄生密切相关。
Objective To probe the histopathological changes of the skin tissue infected with human Demodex on the face. Methods The skin tissues were collected from the persons infected with Demodex, paraffin imbeded and made serial sections stained with hematoxylin-eosin. The histopathologic observation was conducted under microscopy. Results The results showed that mites parasitized in the hair follicles or sebaceous gland, showing the dilated irregular of hair follicles or normal structure of hair root disappeared, proliferated hypertrophy of sebaceous gland. The inflammatory cells were usually observed around the mites. Conclusion The hair follicles dilated, sebaceous gland proliferated and inflammatory reaction are nearly related with the infection of Demodex. It is suggested that these mites were pathogenic in some skin diseases.
