Rare Association Between Lichen Planus and Vogt-Koyanagi-Harada Syndrome: A Case Report.

Vogt-Koyanagi-Harada syndrome (VKHS) is a rare inflammatory autoimmune condition that affects tissues with high melanocyte concentrations such as the skin, inner ears, eyes, and central nervous system. VKHS has previously been reported to be associated with various autoimmune diseases, but we have observed the first known co-occurrence of VKHS and lichen planus (LP). In this report, we examine the similarities between these two diseases and discuss how they relate to each other.
