[Lichen striatus; histologic features (author's transl)]

The histologic picture of lichen striatus is not uniform and changes, as it seems, with the "oldness" of the lesion; showing: sometimes a dense lympho-histiocytic infiltrate of the papillary dermis and epidermis, sometimes features of atypical lichen planus. The existence of spongiotic vesicles in the low epidermis and in certain late forms, pictures of disruption of the basal layer with residual cavities compose particular data of the disease.
