Summary
This case study details the first instance of isolated ocular lichen planus (LP) in a child, presenting as severe dry eye and conjunctival scarring. Treatment with immunosuppressants achieved disease remission.
Area of Science:
- Ophthalmology
- Dermatology
- Autoimmune Diseases
Background:
- Lichen planus (LP) is an autoimmune inflammatory condition affecting skin and mucous membranes.
- Ocular involvement in LP is rare and has not been previously documented in pediatric cases.
Observation:
- An 8-year-old girl presented with severe dry eye, conjunctival hyperemia, and bilateral symblepharon.
- Conjunctival biopsy revealed fibrinogen deposits, indicative of LP, without other immunoglobulin or complement deposition.
Findings:
- The diagnosis of isolated conjunctival lichen planus was made, as no skin or other mucosal lesions were present.
- The patient experienced sustained disease remission following treatment with oral and topical cyclosporine, methotrexate, and low-dose oral steroids.
Implications:
- This case establishes the first report of isolated ocular lichen planus in a pediatric patient.
- It highlights the importance of considering LP in children presenting with severe, unexplained ocular inflammatory conditions.
- The successful treatment regimen suggests potential therapeutic strategies for this rare condition in children.
