Summary
A woman experienced migratory facial swelling due to Gnathostoma infection, a parasitic disease potentially increasing in areas with raw fish consumption. Surgical removal of the worm was successful.
Area of Science:
- Parasitology
- Ophthalmology
- Infectious Diseases
Background:
- Gnathostomiasis is a foodborne parasitic infection caused by Gnathostoma species.
- Consumption of raw or undercooked freshwater fish is a primary transmission route.
Observation:
- A 42-year-old Mexican woman presented with a four-year history of migratory, pruritic, and painful facial swellings.
- Ocular involvement included palpebral edema and conjunctival erythema.
- A mobile worm was observed in the anterior chamber during an eye examination.
Findings:
- Surgical removal of the intraocular worm was performed.
- Microscopic analysis identified the parasite as an advanced third-stage larva of Gnathostoma sp.
Implications:
- This case highlights Gnathostoma infection presenting with ocular manifestations.
- The prevalence of Gnathostoma helminthiasis may be rising in regions where consuming raw freshwater fish, like cebiche, is common.
- Increased awareness and diagnostic vigilance are crucial in endemic areas.
