Lichen planus in association with malignancy- a new paraneoplastic marker - report of two cases

Lichen planus (LP) is an immune-mediated disease, affecting skin and mucous membranes. It has been reported to be associated with a variety of totally unrelated disorders including different malignancies. We report two cases of internal malignancy in whom concomitant cutaneous LP was diagnosed. Can cutaneous LP be a paraneoplastic marker, needs further evidence.
