Lichen planus. large-area lichen planus formed by aggregation of small papules (see upper edge of the large plaque in the middle of the picture). distinct lichenification; only moderate passagonal itching. wickham's pattern is recognizable.

Lichen planus. in a 34-year-old man there are whitish, partly circulatory smooth plaques in the area of the glans penis and the prepuce. in addition, there is a white reticular structure of the buccal mucosa of the cheek.

lichen planus. 0,4-0,6 cm large, itchy, red, rough papules. beginning of a dissociative transformation of the lichen planus. these "wart-like" transformations are mainly observed on the lower legs (localization-related influence)

Lichen planus classical type: linear arrangement of confluent papules (Köbner phenomenon)

Lichen planus. chronically active, multiple, increasing, disseminated standing, partly confluent, first appearing about 6 months ago, mainly localized at the inner edge and back of the foot, 0.3-0.6 cm large, itchy, red, smooth, shiny papules in a 46-year-old woman. similar papules appeared on both inner wrist sides. Furthermore, a whitish, net-like pattern of the buccal mucosa of the mouth appeared.

Lichen planus (classic type): moderately itchy, disseminated, like scattered distribution pattern, red-violet colour of the surface smooth, shiny papules and plaques.

Lichen planus. chronically active, multiple, disseminated or confluent, increasing, first appearing about 6 months ago, mainly localized at the outer edge and back of the foot, 0.3-0.6 cm large, itchy, red, smooth, shiny papules in a 46-year-old woman. Furthermore, a whitish, reticular pattern of the buccal mucosa of the mouth was visible.

Lichen planus (classic type): extensive infestation of the soles of the feet. At the treads, the (classic) morphological structure of the LP is no longer recognizable due to an even confluence of efflorescences. In the area of the hollow foot, diagnosis per aspect is possible.

Lichen planus. overview with pathognomic fine-tissue architecture of the LP. ligamentous (not reaching into the deeper parts of the dermis) lymphocytic infiltrate which is "crowded" closely to the epithelium. moderate, continuous acanthosis and hypergranulosis as well as severe orthohyperkeratosis. in the right section of the picture distinct cleft formation in the area of the dermo-epidermal junction zone.

lichen planus. detail enlargement: interface dermatitis with sawtooth-like acanthosis. characteristic features are "blurring" of the intercellular boundaries, hypergranulosis, orthohyperkeratosis and epidermotropic lymphocytic infiltrate. distinct vacuolar degeneration of the basal keratinocytes
