Actinic lichen planus mimicking lentigines in an elderly Korean woman

A 68-year-old Korean woman presented with a recurrent eruption on her temple. The clinical findings were compatible with a diagnosis of actinic lentigines. However, the biopsy from the lesion revealed histological findings of typical lichen planus. We concluded that the patient had an atypical form of actinic lichen planus that mimicked actinic lentigines. This case is of interest because the condition that is described is rare in elderly and East Asian patients. This is also an atypical form of actinic lichen planus mimicking actinic lentigines.
