- Classification: Alopecia areata
- Alopecias are divided into scarring and nonscarring forms.
- When evaluating a patient who complains of hair loss,
- It is most important to determine if follicular markings are present or absent.
- Present follicular markings suggest nonscarring alopecia;
- Absent follicular markings suggest scarring alopecia.
- Alopecia areata is occasionally associated with autoimmune disorders, including Hashimoto thyroiditis, pernicious anemia, Addison disease, and vitiligo.
- Additional comorbidities may include SLE, atopy, and mental health disease.
