Correlation between reflectance confocal microscopy and high-magnification dermoscopy findings in lentigo maligna of the external ear

The differential diagnosis of pigmented macules developing in the head and neck area may be challenging. Non-invasive imaging methods, including dermoscopy, reflectance confocal microscopy (RCM) and super-high magnification dermoscopy, enable more accurate assessment and increase diagnostic sensitivity and specificity. The present study reports a patient with lentigo maligna (LM) in an uncommon location of the external ear and presents dermoscopic and RCM features. The authors would like to highlight the close correlation between findings in super-high magnification dermoscopy and RCM. Additionally, in agreement with international experts, the diagnosis of a junctional nevus developing on chronically sun-exposed skin of the head and neck area is questioned.
