Lichen skin disorders 

Some of the inflammatory skin conditions characterized by the appearance of coloured flat topped itchy bumps or rashes are called lichen planus. These lichen skin conditions appear on any part of the body or in the mucosal layer that lines the mouth or genital area. In the mucosal layer it appears differently. There are many types of lichen planus like –

Classic lichen planus where the lesion appears as small, flat-topped, and itchy bumps on the arms, legs, and trunk

Oral lichen planus where the white lacy patches appear over the tongue, gums, or inner side of cheeks

Hypertrophic lichen planus is where the rashes are thick and scaly appearing on any part of the skin and are considered more difficult to treat than classic lichen planus.

Lichen planus pemphigoid where blisters are formed.

Lichen planus pigments where dark-coloured hyperpigmented patches develop on the skin.

Healthcare providers diagnose the lichen planus with physical examination and in some cases recommend skin biopsy for the confirmation of the disease. Treatment is also considered depending upon the site of the disease and severity.
