Background:

  • Alopecia areata (AA) is a nonscarring, autoimmune inflammatory condition causing hair loss.
  • The scalp is the most frequently affected site, but hair loss can occur on the body.
  • The precise etiology and pathogenesis of alopecia areata are currently unknown.

Purpose of the Study:

  • To discuss the known etiologic and pathogenic mechanisms of alopecia areata.
  • To review current treatment options for alopecia areata.
  • To provide a comprehensive overview of alopecia areata.

Main Methods:

  • Literature review of existing studies on alopecia areata.

Main Results:

  • Histopathology reveals increased catagen and telogen follicles.
  • A characteristic finding is peribulbar lymphocytic infiltrate, termed "swarm of bees".
  • Corticosteroids represent the most frequently utilized treatment modality.

Conclusions:

  • Alopecia areata is a complex autoimmune disorder with unknown origins.
  • Further research is needed to elucidate the underlying mechanisms.
  • Current management primarily relies on corticosteroids, with ongoing exploration of alternative therapies.
