Cutaneous myiasis: Think beyond furunculosis

Abstract

BackgroundCutaneous myiasis is the infestation of the skin by larvae (maggots) of the order Diptera (two winged). Being an imported and sporadic illness, furuncular myiasis often poses a diagnostic challenge to the treating physician. This traditionally endemic entity is being more frequently reported worldwide as ‘vacation’ disease in travellers returning from these regions. However, there is a paucity of large scale study, especially on individuals occupationally stationed for longer periods of time in these endemic geographic locations. MethodsSixteen Indian male patients with cutaneous furuncular myiasis presenting to dermatology outpatient department at a tertiary care field hospital deployed in a United Nations peacekeeping mission in Central Africa were studied for clinical presentation, sites involved, larvae/maggot extracted, period of resolution and complications if any. ResultsAverage age of patients was 29 years. The average duration of infestation was 4 days. All lesions were found to be confined to sites over body normally covered with clothing, commonest being anterior abdomen in 9 (56.25%) patients followed by chest in 6 (37.5%) patients. The lesion count was also highest on anterior abdomen with 39 lesions. The average time to resolution following extraction of larvae (Cordylobia anthropophaga) was 6 days. ConclusionThe purpose of this study was to familiarize oneself with an endemic infestation which often masquerades itself as pyoderma to the naïve physician, more so in an imported case or more importantly, an ‘exported’ health care professional.
