Is lichen planus pigmentosus a cancerous condition?
Lichen planus pigmentosus (LPP) is not a type of cancer and is generally not associated with an increased risk for cancer. However, one case of LPP has been reported in association with Bazex syndrome and head and neck cancer.
It has been recognized that other types of lichen planus are rarely associated with cancer. For example, bullous lichen planus, a rare form of lichen planus in which blisters form within the characteristic papules, is the subtype that is most frequently linked with cancer. A risk for oral cancer (approximately .5-2%) has also been reported in people affected by oral lichen planus.

How might lichen planus pigmentosus be treated?
There is currently no consensus about treatment for lichen planus pigmentosus (LPP). Management includes avoiding things that make it worse in each case, such as sun exposure or friction in body folds (via weight loss or wearing loose clothing).
No treatment options have shown consistent responses, and evidence of successful treatment has been limited to a few case series. Treatment options may include:
