6. Lentigo maligna

 
Quotation from the 9th edition of Lever's:
 
"It is controversial whether lentigo maligna should be regarded as a form of melanoma in situ in all cases, or whether some cases should be regarded as precursor lesions (lentigo maligna) of in situ melanoma (melanoma in situ, lentigo maligna type). It has been suggested that the risk of progression from lentigo maligna to invasive lentigo maligna melanoma may be about 5%, although some cases may progress rapidly."
 
Reference in the 9th edition to concepts contrary by A. Bernard Ackerman et al. (ABA): None.
 
Statements contrary by ABA:
 
"During the past 30 years, however, histopathologists have avoided making specific diagnoses of malignant melanoma in situ by utilizing a variety of nondiagnostic, euphemistic descriptions for it such as melanotic freckle of Hutchinson, melanosis circumscripta precancerosa of Dubreuilh, active junctional nevus, lentigo maligna, atypical melanocytic hyperplasia, melanocytic dysplasia, and melanocytic intraepithelial neoplasia. Each of these terms evades a specific diagnosis of malignant melanoma in situ, a diagnosis than can, and should, be made clinically and histopathologically if reliable criteria are used."
