Overview

Literature review uncovers immunopathologic overlaps between pityriasis lichenoides and mycosis fungoides, indicating clinical implications.

Key Points

  • A subset of pityriasis lichenoides may have a closer association with mycosis fungoides, impacting diagnosis.
  • Findings include distinct T-lymphocyte clonality and aberrant immunohistochemical phenotypes in select cases.
  • Heightened clinical awareness is necessary for certain pityriasis lichenoides cases to improve patient outcomes.
  • This review examines the histopathologic and immunopathologic features that overlap with mycosis fungoides.
