It is possible that the main title of the report Conjunctivitis, Ligneous is not the name you expected.
Ligneous Conjunctivitis is a rare disorder that is characterized by recurrent lesions of the mucous membranes, especially in the eye. This disorder usually presents itself during childhood and may also be found in the mucous membranes of the larynx, vocal chords, nose, trachea, bronchi, vagina, cervix, and gingiva. The lesions in the mucous membranes have a wood-like (ligneous) consistency to them and are thick, firm, knotty and tough. The cause of this disorder is not known although there have been multiple cases of siblings with this condition suggesting an autosomal recessive inheritance.
