  Therefore, our patient’s family was referred to the National Alopecia Areata Foundation website (https://naaf.org/) for resources on discussing alopecia with school-aged children. [mdedge.com]

  Mild cases have hair loss limited to the scalp, while severe cases show generalized alopecia. Hair shaft abnormalities are characteristic, demonstrating regularly-spaced, spindle-shaped swellings. [medicaljournals.se]

  In addition, and as in alopecia areata, we offer an immunological theory as an explanation because of the presence of the lymphocytic infiltrate, especially around hair follicles. [azmj.eg.net]
