One Case of Benign Lichenoid Keratosis / 대한피부과학회지

ABSTRACT

We present a case of BLK developed in a 43-year-old Caucasian female. She had an asymptomatic, 4mm-sized, scaly erythematous papule on her left forearm. On histologic examination, this case showed a focal parakeratosis, hyperkeratosis, focal hypergranulosis and basal vacuolar degeneration in the epidermis, as well as band-like lymphohistiocytic infiltration with melanophages and solar elastosis in the dermis. The skin lesion was totally excised and no recurrence was noted.
