"This is a beautiful atlas of color photographs of rare and common pigmentary disorders. The emphasis is on the photographs that show a high level of detail of characteristic pigmentary changes. ... The purpose is to educate physicians on recognizing and diagnosing more accurately pigmentary disorders. The audience is physicians. ... I enjoyed seeing rare syndromes that are not covered in other books on pigment disorders." (Patricia Wong, Doody's Book Reviews, December, 2016)
