Who is at Risk for Lichen Simplex Chronicus?
LSC is more common in adults but maybe seen in children with a history of eczema. LSC can also arise due to chronic itch as a result of underlying nerve changes. More common in people with anxiety and obsessive chronic disorder.

LSC appears as dark red or purplish raised lesions. The texture can be somewhat leathery in appearance and may have scratch marks. They can be located in easily reached areas oftentimes affecting the back of the neck/scalp, lower legs, wrist and forearms. Similar skin changes can also occur in the genital area, especially the scrotum, vulvua, or perianal area.
How is Lichen Simplex Chronicus Diagnosed
LSC is diagnosed based on its appearance. A skin biopsy is sometimes needed to confirm diagnosis or rule out secondary fungal infections.
