Abstract

The dermatologic lesions of the external ear are quite protean and they encompass pre-malignant, malignant and inflammatory entities. The ear is endowed with functional and cosmetic importance and it is part of the "H-zone", which is the area of the head that generally presents tumors that can be considered high risk regardless of their size. As a matter of fact, skin malignancies of the ear tend to have a less benign course compared to the ones located on other areas of the body and complete excision has proven to be challenging. This mini-review provides an overview on the malignant cutaneous lesions of the external ear with a focus on their dermoscopic and reflectance confocal microscopy features. The most prevalent neoplasms of the auricle are squamous cell carcinoma and basal cell carcinoma followed by melanoma. These malignant lesions appear to be more common in men and to have a worse prognosis compared to when they arise from other body districts. There is a relative dearth of large studies centered on the clinical, dermoscopic and reflectance confocal microscopy features of skin cancers of the ear. Hence, further research inquiring into the specific dermoscopic and reflectance confocal microscopy characteristics of the cutaneous malignant lesions of the external ear, if any, are warranted for the future.
