Abstract
|
|
|
|
Lichen spinulosus (LS), a disorder of keratinization, is characterized by 1 to 3 mm sized follicular keratotic papules with a central horny spine that are grouped into large patches. Involved lesions were symmetrically distributed over extensor surfaces of the arms and legs, back, chest, face and neck. Although the exact etiology is unknown, several factors such as atopic dermatitis, infections and genetic components have been proposed as playing a role in LS. Additional associations reported in the literature include Crohn’s disease, Hodgkin’s disease, HIV infection, administration of omeprazole, and seborrheic dermatitis. Herein, we report a case of wide spread lichen spinulosus occurring on a preexisting seborrheic dermatitis lesion in a 50-year-old woman.
