Spontaneous remission of cutaneous LP after 1 year occurs in two-thirds of cases.1 Patients mainly complain of pruritus. The spontaneous remission of oral LP is much rarer and may occur in approximately 5% of patients. The reported mean duration of oral LP is about 5 years, but the erosive form does not resolve spontaneously.2 The erosive form can be extremely painful, leading to major weight loss because of dysphagia. Malignant transformation of oral LP has occasionally been described. Nail or scalp involvement may result in irreversible scars.
