Asymptomatic eosinophilia due to gnathostomiasis

Area of Science:

• Parasitology
• Infectious Diseases
• Dermatology

Background:

• Gnathostomiasis diagnosis typically relies on eosinophilia, migratory skin lesions, and exposure history.
• Cutaneous manifestations are diverse, often including migratory swellings and creeping eruptions.

Observation:

• This report details a unique case of gnathostomiasis.
• The patient presented with fever and eosinophilia.

Findings:

• The case is the first documented instance of gnathostomiasis without characteristic cutaneous migratory lesions.
• Internal organ involvement was also absent in this presentation.

Implications:

• This atypical presentation expands the differential diagnosis for fever and eosinophilia.
• Clinicians should consider gnathostomiasis even in the absence of typical skin findings.
