Management rules to detect melanoma.

Most melanomas are easy to be diagnosed clinically and dermoscopically. The question remains open concerning the correct strategies to detect those melanomas that look morphologically inconspicuous from a clinical and/or dermoscopic point of view. In our estimation, when morphology is not enough to recognize melanoma, one has to use specific management strategies. Herein we summarize the following 7 simple and practical rules that outline the need for a more general approach integrating clinical information with dermoscopic examination: (1) Look basically at all lesions. (2) Undress high-risk patients. (3) Use the 10 seconds rule in single lesions. (4) Compare and monitor multiple moles. (5) Excise doubtful nodular lesions. (6) Combine clinical and dermoscopic criteria. (7) Combine clinical and histopathologic criteria.
