[Conjunctivitis lignosa]

A 57-year-old woman patient presented with a pseudo-membranous necrotizing conjunctivitis. The biopsy exhibited histological changes typical for conjunctivitis lignosa with definite vasculitis, vascular occlusions and vascular necrosis. The clinical course was typical for conjunctivitis lignosa. The histological findings would suggest a circumscribed conjunctival vasculitis underlying the conjunctivitis lignosa.
