Facial pigmented actinic keratosis (AK) is a differential diagnosis of lentigo maligna because it can have the same clinical and dermoscopic aspects: asymmetric pigmented follicles, annular-granular structures, and rhomboidal structures. Possible clues for pigmented actinic keratosis are scales and a superficial broken-up network usually not present in lentigo maligna.
In our case dermoscopy revealed annular-granular pattern. A biopsy was performed and pathology revealed a pigmented actinic keratosis.
