Migratory facial swelling due to gnathostomiasis
1Department of Oral Pathology, Faculty of Dentistry, Chiang Mai University, Thailand.
Summary
Facial gnathostomiasis, caused by the roundworm Gnathostoma spinigerum, presents as migratory facial swelling. Prevention involves avoiding undercooked meat, as effective treatments are currently limited.
Area of Science:
- Medical Parasitology
- Infectious Diseases
Background:
- Gnathostomiasis is a parasitic infection caused by Gnathostoma spinigerum.
- It is prevalent in endemic areas like Southeast Asia.
Observation:
- Two female Thai patients presented with intermittent and migratory facial swelling.
- This swelling is characteristic of facial gnathostomiasis.
Findings:
- Currently, no consistently effective therapy exists for gnathostomiasis.
- Surgical removal is curative but often unsuccessful due to the parasite's rapid movement in tissues.
Implications:
- Gnathostomiasis should be considered in differential diagnoses for unexplained oro-facial swelling in endemic regions.
- Public health education on safe food practices, particularly avoiding undercooked meat and fish, is crucial for prevention.
