Complications
Lichen spinulosus is confined to the skin and has no known associations with internal disorders or genetic syndromes.
Prognosis
Lichen spinulosus can be ameliorated using emollient keratolytics. Case reports suggest that cure is the result of spontaneous remission over time. Most cases appear to remit within 1-2 years; however, well-documented cases exist that have lasted for decades.
