Myiasis is a tropical disease due to tissue invasion b ythe larvae of certain flies, principally the tumbu fly (Cordylobiaanthropophaga) and the human botfly (Dermotobia hominis).These larvae may be contracted via the bite of mosquitoes like Hypoderma bovis and Chrysomya bezziana, and may present with local or systemic clinical effects.
An unusual infestation of the skin and gastrointestinal tract by Dermatobia hominis in a Nigerian patientis reported.
The index patient presented with pyrexia of unknown origin. Papules with a central pore were seen on the skin from which maggots were mechanically extracted, facilitated by the application of petroleum jelly. The extracted larvae were characterised as Dermatobia hominis. Identical larvae were isolated from the patient's stool sample.
Myiasis does occur in our environment and patience and thoroughness are required in order to clinch the diagnosis. This is the first case of Dermatobia hominis reported in Nigeria either as Cutaneous/Gastrointestinal system or both and one of the few cases published in Africa in an African residing in Africa without a recent travel to South America where it is endemic. This public health importance of this condition is discussed.
蝇蛆病是一种热带疾病，由某些苍蝇的幼虫侵入组织引起，主要是嗜人瘤蝇（Cordylobia anthropophaga）和人肤蝇（Dermotobia hominis）。这些幼虫可能通过牛蝇（Hypoderma bovis）和嗜尸金蝇（Chrysomya bezziana）等蚊子叮咬而感染，并可能出现局部或全身临床症状。
报告一例尼日利亚患者人肤蝇对皮肤和胃肠道的罕见感染。
该索引患者表现为不明原因发热。皮肤上可见有中央小孔的丘疹，通过涂抹凡士林便于从丘疹中机械取出蛆虫。取出的幼虫鉴定为人肤蝇。从患者粪便样本中分离出相同的幼虫。
蝇蛆病在我们的环境中确实存在，为确诊需要耐心和细致。这是尼日利亚首例报告的人肤蝇感染皮肤/胃肠道系统或两者的病例，也是非洲少数在非洲居住且近期未前往该病流行的南美洲的非洲人所发表的病例之一。本文讨论了这种疾病的公共卫生重要性。
