蝇蛆病(myiasis)是双翅幼虫侵入人体或其它哺乳类动物活组织中所引起的一种疾病。蝇将卵产在开放性伤口或自然腔道,然后孵化为幼虫,幼虫从坏死组织内获取营养,发育成蛹。该病由Hope于1840年首次报告,各年龄组均可发病,但新生儿多见且严重甚至引起死亡。口腔蝇蛆病非常罕见,Scott报告了120例蝇蛆病,而口腔蝇蛆病只有1例。该病1909年由Laurence首次报道,此后又有11例,本文报告了另1例。病例报告:69岁农民,于1985年6月主诉2天来下 Myiasis is a disease caused by the penetration of two-winged larvae into the tissues of humans or other mammals. Flies lay their eggs in open wounds or natural lanes and then hatch as larvae, which acquire nutrients from necrotic tissues and develop into pupae. The disease was first reported by Hope in 1840 and was reported to occur in all age groups, but newborns are more common and cause severe death. Oral myiasis is very rare, Scott reported 120 cases of myiasis, and oral myiasis in only 1 case. The disease was first reported by Laurence in 1909, and since then there are 11 more cases reported in this article. Case Report: A 69-year-old farmer who complained in two days in June 1985
