title: Pulmonary involvement in a child with ligneous conjunctivitis and homozygous type I plasminogen deficiency.
abstract: Ligneous conjunctivitis (LC) is a rare disorder characterized by a chronic course of recurrent membranous lesions at conjunctivae. Pseudomembranes of other mucous membranes have been reported in patients with LC, but to the best of our knowledge, no case with alveolar involvement has been described. Here, we report a 2.5-year-old girl with LC who had tracheoaveolar involvement and homozygous type I plasminogen deficiency. Tracheal involvement was diagnosed by bronchoscopic biopsy and alveolar involvement with postmortem biopsy. She was shown to be homozygous for frameshift mutation in plasminogen exon 14 (Gly565ins-G) with molecular genetic examination of DNA which was obtained from parafin embedded postmortem lung tissue. Ligneous inflammation of the upper and lower respiratory tract must be considered in children with LC and recurrent respiratory tract problems.
