title: Palmoplantar lichen planus.
abstract: Palmoplantar lichen planus (PPLP) is an uncommon variant of lichen planus that affects the palms and soles. Clinical findings are varied although they have been conceptualized into two large groupings, an erythematous scaly pattern and a hyperkeratotic pattern. Histopathologic features are those of classic LP. We present a case of PPLP that improved with methotrexate after failing treatment with acitretin.
