Lichen Planus Diagnosis

Lichen Planus can be diagnosed clinically by experienced eyes. Lesions on the skin have typical look as described elsewhere on this pages, and their location such as legs, back, mouth, scalp, genitals, nails, or elsewhere (more or less in this order) is important for diagnosis.

Sometimes the Lichen Planus eruptions, especially in early states, may resemble to some other diseases like atopic dermatitis, psoriasis, candidiasis (in mouth), Leukoplakia (mouth), apthous ulcers (mouth).

In case of doubt, or to confirm the diagnosis, a biopsy would help. Biopsy is more often indicated in cases of oral and scalp Lichen Planus. Also, Lichen Planus of nails alone could resemble psoriatic nails and fungus infection of nails.
