Lichen Spinulosus

Abstract

One 8 year girl had repeated crops of mildly pruritic, erythematous plaques studded with follicular papules showing prominent antenna sign on sides of neck, trunk (more on back), buttocks and extensors of limbs since one year. Plaques increased in size for 7-8 days, remained stationary for 20-22 days and resolved slowly after another 14-15 days. Erythematous colour changed from dark brown to orangish yellow to yellow to pale yellow to normal skin colour. Discrete follicular papules with antenna sign were also present. Her mother had bronchial asthma.
