[Vogt-Koyanagi-Harada disease. About two observations (author's transl)].
After a reminder of clinical symptoms and development of the V.-K.-H. disease, some histological and clinical observations are related. The clinical observations are very characteristic of the V.-K.-H. disease. There are only two notable points: in both observations, a very low lymphocytic reaction to phytohemaglutinin and in the first observation, the presence of an anemia with parallel evolution to the uveitis. The histological examination of the depigmented area shows an infiltrate as described by Perrot, around the involved area in vitiligo. Ultrastructural study identifies 250 angströms wide particles that appear to be particles of alpha-glycogene, well developed amyelinic endings, and lastly, lymphocytoid cells closely joined with dendritic cells having internal granulations. These aspects have already been found in the iris by the Japanese authors, and they evoked an immunological mechanism.
