Is there a role for the radiologist in dermatology?

There are at least 100 entities that present a significative conjunction between skin signs and skeletal or other bony changes that can be detected by radiological means (skin and bones and others). The aim of this article is to underline that sometimes a radiological examination could guide to a correct diagnosis in dermatology. In addition, bloody diagnostic procedures could be avoided in ambiguous skeletal lesions if the radiologist remembers that skin and bone diseases exist. We review the literature and suggest a practical classification, including skin markers of occult radiological changes, skin diseases often associated with skeletal or other bony changes that require a radiological evaluation for a diagnosis, radiological changes mimicking cutaneous diseases, skeletal side effects of dermatological therapies (topical and systemic) and skin lesions occurring as a consequence of bone injury.
