| Popis: |
A 36-year-old male patient presented with unilateral periocular skin atrophy. The blepharochalasis developed without any obvious inflammation of the eyelids over the past 10 years. Interestingly, elongated blood vessels and microaneurysmatic vessel changes were found in the tarsal conjunctiva. A punch biopsy revealed a nearly complete loss of elastic fibres in the papillary and superficial reticular dermis. The contralateral side was histopathologically normal. On immunohistology IgA-deposits could be observed especially on perifollicular elastic fibres. Immunoelectronmicroscopy confirmed the diagnosis and suggested fibulin and fibronectin as potential binding sites for the autoantibodies. This further report of elastolysis in association with IgA-autoantibodies defines the autoantibody binding site in more detail and suggests that the immune mechanisms may also play a role in vessel changes of the conjunctiva. |
