Pigmented actinic lichen planus (PALP) mimicking lentigo maligna melanoma: Usefulness of in vivo reflectance confocal microscopy in diagnosis and follow-up

Abstract

A 40-year-old white man was referred to our clinic for an asymptomatic pigmented patch on his right cheek for 2 months that did not have seasonal variation. Clinically, the lesion was a slightly and irregularly pigmented patch of about 6 × 3 cm (Fig 1). The patient had no history of trauma or sunburn; no drugs were taken in the previous months.
