Summary
Phthiriasis palpebrarum, a pubic lice infestation of the eyelids, can cause persistent itching and be misdiagnosed. Early recognition and mechanical removal of lice and nits are key to successful treatment.
Area of Science:
- Ophthalmology
- Dermatology
- Parasitology
Background:
- Phthiriasis palpebrarum, caused by Phthirus pubis (pubic lice), is an uncommon cause of blepharoconjunctivitis.
- It is often overlooked due to a lack of physician recognition of pubic lice infestation on the eyelids.
Observation:
- A 30-year-old woman presented with persistent left eyelid itching, initially diagnosed and treated unsuccessfully as allergic blepharoconjunctivitis.
- Ophthalmic examination revealed live lice, characteristic excretions, and numerous eggs (nits) on the eyelashes.
Findings:
- Histopathological examination confirmed the presence of Phthirus pubis infestation.
- Mechanical removal of all lice and nits from the eyelashes resulted in successful treatment.
Implications:
- While typically associated with poor hygiene, increased travel may lead to more frequent cases of Phthirus pubis infestation in developed regions.
- Ophthalmologists and primary care physicians should consider Phthiriasis palpebrarum in cases of persistent blepharoconjunctivitis unresponsive to standard treatments.
