Parasitic Infections

Area of Science:

• Medical Parasitology
• Dermatology
• Infectious Diseases

Background:

• Gastrointestinal parasitic infections affect millions globally, primarily in areas with poor sanitation.
• While systemic effects are well-documented, the associated cutaneous manifestations are less frequently reported.
• Perianal skin irritation is a common, yet often overlooked, symptom of these infections.

Purpose of the Study:

• To review the spectrum of perianal cutaneous findings associated with common gastrointestinal parasitic infections.
• To highlight the diagnostic and management challenges of these dermatological presentations.
• To consolidate information on amebiasis, schistosomiasis, Enterobius vermicularis, strongyloidiasis, and cutaneous larva migrans.

Main Methods:

• Literature review focusing on parasitic infections with perianal cutaneous manifestations.
• Analysis of reported clinical presentations, from pruritus ani to ulceration.
• Compilation of current management guidelines for identified parasitic infections.

Main Results:

• Cutaneous findings range from mild pruritus ani to macular rash and severe perianal ulceration.
• Specific parasites discussed include Entamoeba histolytica (amebiasis), Schistosoma species (schistosomiasis), Enterobius vermicularis, Strongyloides stercoralis, and Ancylostoma/Uncinaria species (cutaneous larva migrans).
• Early recognition of cutaneous signs is crucial for timely diagnosis and treatment.

Conclusions:

• Perianal skin manifestations are significant indicators of gastrointestinal parasitic infections.
• Integrated diagnostic approaches are needed to address both intestinal and cutaneous symptoms.
• Effective management relies on accurate identification of the parasite and appropriate antiparasitic therapy.
