Generalized Annular Lichen Planus / 대한피부과학회지

ABSTRACT

Generalized annular lichen planus is rarely described and is characterized by generalized flexural eruptions without involvement of oral mucosa. A 43-year-old male presented with mildly pruritic erythematous to brownish annular macules, confluent patches with peripheral elevated rim for 5 months. The annular lesions involved abdomen, back, upper and lower extremities, predominantly distributed on flexural areas such as both axillae, inguinal areas and popliteal fossae. Histopathologic features from abdomen lesion were compatible with lichen planus. The patient was treated with methylprednisolone, hydrochloroquine and dapsone for 8 weeks and all erythematous lesions disappeared with remaining marked hyperpigmentation.
