2. Dysplastic nevus

 
Quotation from the 9th edition of Lever's:
 
"Dysplastic nevi form, clinically and histologically, a continuum extending from a common nevus to a superficial spreading melanoma."
 
Reference in the 9th edition to concepts contrary by A. Bernard Ackerman et al. (ABA):
 
Ackerman AB, Mihara I. Dysplasia, dysplastic melanocytes, dysplastic nevi, the dysplastic nevus syndrome, and the relation between dysplastic nevi and malignant melanomas. Hum Pathol. 1985 Jan;16(1):87-91.
 
Ackerman AB, Briggs PL, Bravo F. Dysplastic nevus, compound type vs. Clark's nevus, compound type. In Ackerman AB, Briggs PL, Bravo F, eds. Differential Diagnosis in Dermatopathology III. Philadelphia: Lea & Febiger, 1993 :158-161.
 
No references to ideas of ABA published since 1993. Moreover, no reference was made to Dysplastic Nevus: Atypical Mole or Typical Myth (Ackerman AB, Massi D, Nielsen TA. Philadelphia, Ardor Scribendi, 1999), the only volume dedicated exclusively to the subject.
 
Statements contrary by ABA:
 
"The perplexing story of the dysplastic nevus and the dysplastic nevus syndrome can be comprehended only in the context of understanding the consistent lack of a repeatable definition of dysplasia and the persistent failure to provide reliable criteria for clinical and histopathologic diagnosis of dysplastic nevus. As a consequence of these rickety underpinnings, it was inevitable that the edifice would collapse, and it did in less than 15 years. The epitaph for dysplastic nevus was written in 1992, and that was published in the Journal of the American Medical Association in 1992. In that report, the panel stated that the term dysplastic nevus had outlived its usefulness and should be abandoned. We concur and advise further that the concepts of dysplasia, dysplastic melanocytes, dysplastic nevus, and the dysplastic nevus syndrome not only be abandoned now, but that they also not be supplanted by equally opaque notions, such as cytologic and architectural atypia, nevus with histologic dysplasia, clinically atypical mole, and atypical mole syndrome."
