title: Follicular mycosis fungoides: a case report and review of the literature.
abstract: BACKGROUND
  Follicular mycosis fungoides is an unusual variant of mycosis fungoides (MF). Unlike classic MF where atypical lymphocytes show a predilection for the epidermis (epidermotropism), follicular MF displays a malignant lymphocytic infiltrate tropic for hair follicles (folliculotropism). This malignant lymphocytic infiltrate results in follicular disruption typically manifesting clinically as plaques, comedones and follicular papules.
  
  
  METHODS
  This report describes a 40-year-old patient with follicular MF presenting as nodules on the face and chest. Histologic examination of the patient's biopsy revealed a folliculocentric infiltrate of atypical lymphocytes with sparing of the epidermis.
  
  
  CONCLUSIONS
  Our case is discussed in the context of previously reported cases of follicular MF; we also include a review of all cases of follicular MF published to date that meet the strict criterion for this diagnosis.
