Lichen sclerosus is an uncommon condition that creates patchy, white skin that's thinner than normal. Lichen sclerosus can affect skin anywhere on your body. But it most often involves skin of the vulva, foreskin of the penis or skin around the anus. IInflammation and altered fibroblast function in the papillary dermis leads to fibrosis of the upper dermis. Genital skin and mucosa are affected most frequently, but extragenital lichen sclerosus does occur, and even rare oral presentations are reported.
The role that hypoxia and ischemia have in the initial cellular and vascular damage is supported by the finding of increased glut-1 and decreased vascular endothelial growth factor (VEGF) expression in affected skin.
Gynecological examination, including vaginal inspection, was performed, if necessary in general anesthesia. Median age at symptom start was 51 years (range 17-78 years) with 15 women (26%) being younger than 40 years old. Sexual abstinence was reported by 36 women and dyspareunia by another 10. On examination, vaginal involvement was seen in 49 women, including vaginal synechiae in 29 and total obliteration of the vagina in 9.
