Ligneous conjunctivitis with oral mucous membrane involvement and decreased plasminogen level

Abstract

Ligneous conjunctivitis (MIM 217090) is a rare autosomal recessive hereditary disorder. We report a case with both ligneous conjunctivitis and ligneous periodontitis in association with plasminogen type I deficiency. Diagnosis was based on the clinical and histological findings and most importantly, decreased serum level of plasminogen type I.
