INTRODUCTION
Follicular mucinosis, also referred to as alopecia mucinosa, was initially reported as localized alopecia histopathologically characterized by the deposition of mucin within hair follicles1. The disease is classified as idiopathic follicular mucinosis, which is not associated with other cutaneous or extracutaneous diseases, and as lymphoma-associated follicular mucinosis, which is associated with mycosis fungoides or Sézary syndrome2. Idiopathic follicular mucinosis commonly appears as follicular papules or indurated plaques 3. We herein report a case of idiopathic follicular mucinosis showing characteristic dermoscopic findings.
