Lichen planus follicularis
Type of disease: Rare conditions
Lichen planus follicularis is a form of lichen planus that mainly affects the scalp and primarily affects middle-aged adults. It usually causes tiny red papules to appear around a cluster of hairs. Rarely, blistering occurs in the lesions. The hair follicles on the scalp are mainly affected in this form, although lesions may also be found on the skin and mucous membranes. Follicular lichen planus is the most common form of lichen planus found in the scalp. Commonly encountered symptoms and signs are increased hair shedding, itching, scaling, burning, and tenderness. Hair loss occurs and may be permanent if the disease is sufficiently active to cause permanent scarring, a condition called cicatricial alopecia. Treatment is usually with steroids.
