Summary
This case study details a Phthirus pubis infestation affecting an eight-year-old boy's eyelids. Treatment involved manual removal of pubic lice and their eggs from the eyelashes.
Area of Science:
- Ophthalmology
- Parasitology
- Dermatology
Background:
- Phthirus pubis infestation, commonly known as pubic lice, typically affects the genital area.
- Eyelid involvement is rare, presenting diagnostic and treatment challenges.
Observation:
- An 8-year-old boy presented with bilateral eyelid inflammation unresponsive to conventional treatment.
- Physical examination revealed small, dark spheres on the proximal eyelashes, identified microscopically as adult P. pubis and eggs.
Findings:
- Microscopic analysis confirmed Phthirus pubis infestation of the eyelids, with 23 adult insects and 32 eggs removed.
- No evidence of infestation was found on the patient's scalp.
- The source of infestation was presumed to be the patient's mother, but could not be confirmed.
Implications:
- This case highlights the importance of considering Phthirus pubis infestation in cases of refractory eyelid inflammation, even in children.
- Manual extraction of parasites and eggs, aided by lubricants, is an effective treatment.
- Further research is needed to understand the transmission dynamics and prevention strategies for ocular Phthirus pubis infestations.
