Summary
This case report details a rare instance of orbital myiasis caused by Hypoderma bovis. Prompt surgical intervention and follow-up successfully managed the invasive parasitic infestation and associated basal cell carcinoma.
Area of Science:
- Ophthalmology
- Parasitology
- Dermatology
Background:
- Orbital myiasis, a rare condition caused by invasive parasitic larvae, presents significant destructive potential.
- This report focuses on a unique case of orbital myiasis attributed to Hypoderma bovis.
Observation:
- An 85-year-old female presented with a year-long ocular wound and a one-week history of larvae in the right eye.
- Clinical examination revealed no light perception, a thickened eyelid, and a 3x4 cm necrotic lesion with extensive invasion of orbital and maxillary structures.
- Pathological examination confirmed basal cell carcinoma alongside the parasitic infestation.
Findings:
- Surgical management included orbital exenteration, total maxillectomy, and graft repair.
- A six-month follow-up period using orbital tomography showed no evidence of recurrence or metastasis.
Implications:
- This case highlights the critical need for timely diagnosis and aggressive surgical management in rare orbital myiasis cases.
- It underscores the potential for significant tissue destruction by invasive parasites and the importance of comprehensive oncological and parasitological evaluation.
