1. Terms and Phrases in the Title and the Abstract of the Article in Seminars in Diagnostic Pathology Not Yet Defined in Comprehensible, Repeatable Fashion

 
  • Common acquired nevi
  • Atypical (dysplastic) nevi
  • Tumor progression in the melanocytic system (melanocytic tumor progression)
  • Indeterminate lesions of melanocytic tumor progression
  • Precursors of melanoma
  • Clinical atypia
  • Histological atypia
  • Melanocytic dysplasia
  • Radial growth phase melanoma
  • Early lesions of melanocytic tumor progression
  • Epidemiological data implicating sunlight as an etiologic agent for most melanomas
 
Clark and co-workers, in scores of articles about melanocytic dysplasia, DN, and the dysplastic nevus syndrome (DNS), failed consistently to define terms and phrases employed repeatedly by them. In addition to the terms and phrases just quoted from the title and the abstract of the article published in Seminars in Diagnostic Pathology in 1993, many other terms and phrases have not been made comprehensible by them, among those being:
 
  • Aberrant differentiation
  • Architectural atypia
  • Architectural disorder
  • Atypical melanocytic proliferation
  • Biphasic growth
  • Borderline melanoma
  • Cytoplasmic atypia
  • Epithelioid melanocytic dysplasia
  • Funny looking mole
  • High-grade atypia
  • Lentiginous asymmetry
  • Lentiginous melanocytic dysplasia
  • Microinvasion
  • Minimal deviation melanoma
  • Pagetoid melanocytic proliferation
  • Precancerous melanosis
  • Precursor lesion
  • Precursor state
  • Random cytologic atypia
  • Syndrome
  • Uniform atypia
  • Vertical growth phase melanoma
 
Failure from the beginning to define exactly words and phrases crucial to elucidation of concepts they set forth compromised severely from the outset ideas of Clark and collaborators about "melanocytic dysplasia," "DN," "DNS," and "melanocytic tumor progression."
