Many texts deal with how to diagnose the straightforward melanomas of the skin, but there are many less common skin tumors that a clinician needs to be aware of because these are still likely to be encountered at some point in a clinical setting and many of them have serious implications. This highly illustrated text from an internationally acclaimed researcher provides a reliable guide to how to proceed with diagnosis of these more challenging entities.
