Tinea blepharitis and follicular conjunctivitis in a child.

Trichophyton tonsurans is a fungal species that frequently causes tinea capitis (ringworm), a skin infection found in children. We report a case of unilateral blepharoconjunctivitis due to tinea capitis in a previously healthy 8-year-old boy. Although no case of blepharitis or follicular conjunctivitis due to T. tonsurans has been previously reported, the findings are consistent with other rare causes of ringworm blepharitis. Emerging or chronic fungal blepharitis should be considered in the differential diagnosis of unilateral follicular conjunctivitis.
