Persistent eyelid swelling in a child: lest myiasis be forgot.

Area of Science:

• Ophthalmology
• Parasitology
• Dermatology

Background:

• Myiasis, the infestation of a host by fly larvae, is rarely documented in the eyelid region.
• Preseptal cellulitis is a common eyelid infection in children, often requiring prompt medical attention.

Observation:

• An 8-year-old boy presented with symptoms suggestive of preseptal cellulitis.
• Initial clinical presentation mimicked a bacterial infection of the eyelid.
• A thorough examination led to the identification of a single larva within the eyelid tissue.

Findings:

• The patient was diagnosed with ocular myiasis, specifically involving the eyelid.
• Surgical extraction of the larva was performed successfully.
• Histopathological examination confirmed the presence of a fly larva.

Implications:

• This case highlights the importance of considering myiasis in the differential diagnosis of eyelid infections, even when symptoms appear typical for cellulitis.
• Early and accurate diagnosis is crucial to prevent potential complications associated with myiasis.
• Increased awareness among clinicians can improve patient outcomes for this uncommon condition.
