Abstract:
A case of benign lichenoid keratosis(BLK) developed in a 25-year-old female is presented. She had two erythematous plaques with slightly verrucous surfaces on the lips for 4 weeks. A biopsy specirnen taken from the periphery of the lesion revealed a focal parakeratosis, the absence of granular cells, and hydropic degeneration of the basal cells in the epidermis. The upper dermal infiltrate composed chiefly of lymphacytes intermingled with a few histiocytes was also seen. The direct immunofluorescent study showed depositions of a few cytoid bodies and fibrin around the areas of the dermoepidermal junction. These plaques on her lips, demonstrating lichenoid tissue changes, cleared in 8 weeks from the evalution, without any treatment.
