title: Generalized reticulated hyperpigmentation induced by lichen planus.
abstract: A 68-year-old Chinese woman presented with generalized reticulated dark-brown hyperpigmentation on the trunk, face and limbs, oral Wickham's striae, sparse scalp hair and dark-red reticulated streaks on the occiput of the head and on the neck, some dark-red to violaceous papules on the face, scalp and flanks, light-yellow, deep-seated papules on the palms and soles, and small porcelain-white papules on the dorsal and lateral fingers. The histological features were consistent with the diagnosis of lichen planus (LP). To our knowledge, LP-induced generalized reticulated hyperpigmentation is very rare and this is the first report of the clinical features on the fingers, palms and soles.
