Childhood Furuncular Cutaneous Myiasis Associated with Seborrheic Dermatitis: A Case Report

Myiasis is a parasitic infection caused by dipterous fly larvae that can affect various organs in both human and animals. Cutaneous myiasis is the most common type of myiasis and can be classified into three categories, localized furuncular myiasis, migratory myiasis, and wound myiasis. One of the risk factors for myiasis is seborrheic dermatitis. The definitive treatment for the condition requires complete extraction of larvae, in combination with oral therapy, and localized occlusion to promote hypoxia. This paper reports a case of a 12-year-old girl with furuncular cutaneous myiasis associated with seborrheic dermatitis on the occipital region that showed significant improvements after manual extraction of larvae after local anesthesia injection of 2% lidocaine on the base of the lesion, in combination with oral and topical therapies

Feeding gastrostomy stoma site cutaneous myiasis: a rare entity

Infestation of any dead or necrotic tissues by the larvae of flies (maggots) is myiasis. This form of habitation is not restricted to any particular tissues in the body and can occur anywhere. However, myiasis at the surgical stoma site is very rare. We present a 55-year-old woman diagnosed with metastatic carcinoma of the oesophagus who underwent feeding gastrostomy (FG). The patient later presented with worms at the FG site. We removed the FG tube, cleared all the maggots, thoroughly cleaned the wound and placed a new FG tube. Although its occurrences have been reported enough in medical history, there are only two documented cases of percutaneous endoscopic gastrostomy stoma site myiasis. Hence, we present the first case in the literature of cutaneous myiasis around an FG stoma site.

Wound myiasis in Western Europe: prevalence and risk factors in a changing climate scenario

Summary Background Myiasis is an infestation of neglected open wounds by fly larvae. Global warming, related climate changes, and increased traveling in tropical countries may contribute to the worldwide diffusion of new fly species. Common risk factors for myiasis are advanced age, poor hygiene, malnourishment, social isolation, diabetes, cancer, and peripheral artery disease. The aim of this study was to review the characteristics of cases of myiasis reported in Europe. Methods A narrative review of cutaneous myiasis was performed using PubMed, EMBASE, Web of Science database, and the search terms “human,” “myiasis,” “cutaneous myiasis,” “maggot,” “Europe,” “wound,” with the combination of “AND” and “OR.” In addition, hospital charts were reviewed to add personal experience to the literature review. Results Overall, 52 articles, both single case reports and case series reporting cutaneous myiasis, were found in the medical literature of the past two decades. A total of 64 patients living in Europe were identified, of whom 36% had wound myiasis. In addition to the literature review, we report the case of a male patient who presented with myiasis within a deep scalp ulcer occurring after radiotherapy for basal cell carcinoma. Conclusion Myasis is rare and possibly under-reported in Europe. The epidemiology of this infestation may be changing in the future due to climate variability, a rise in travel to tropical areas, and the migration of fly species.
