Actinic Lichen Nitidus with Dermoscopic Features, and Response to Hydroxychloroquine

Lichen nitidus (LN) is an entity of unknown etiology, with typical morphology and histology. Actinic lichen nitidus (ALN) is rare. It presents as typical lesions of LN in photodistribution, with classical histology. Dermoscopic findings in LN has been documented in very few cases in literature. We present a case of ALN with koebnerization, characteristic histology and dermoscopic features. Dermoscopy revealed round, bluish white streaks in “fern leaf ” pattern in the background of brownish reticular network. Our patient responded well to hydroxychloroquine and photoprotection.
