Area of Science:

  • Dermatology
  • Pathology

Background:

  • Scarring alopecias encompass a range of conditions with varied causes and disease processes.
  • Histological classification distinguishes between primary and secondary scarring alopecias based on reticular dermis involvement.

Purpose of the Study:

  • To outline the classification and key examples of primary and secondary scarring alopecias.

Main Methods:

  • Histological classification based on reticular dermis involvement.
  • Identification of distinct primary and secondary scarring alopecia types.

Main Results:

  • Primary scarring alopecias include pseudopelade, lichen planopilaris, and specific vertex scarring in African-Americans.
  • Secondary scarring alopecias include folliculitis decalvans and late-stage lupus erythematosus.

Conclusions:

  • Understanding the etiological and pathogenetic diversity is crucial for classifying scarring alopecias.
  • Histological assessment aids in differentiating primary from secondary forms, guiding diagnosis and management.
