TLDR Alopecia Areata Incognita causes widespread hair thinning, and treatment with systemic corticosteroids and psychiatric support can lead to remission.
The letter by Alfredo Rebora discusses Alopecia Areata Incognita (AAI), a condition that mimics severe telogen effluvium with a positive pull test and can affect facial hair, leading to diffuse hair thinning and occasionally small bald areas. Rebora, who first described AAI, notes that the modified wash test can yield 350 to 800 terminal telogen hairs, with a small percentage of dystrophic hairs. AAI is distressing, with one patient attempting suicide, and while local corticosteroid treatment was ineffective, systemic corticosteroids combined with psychiatric support led to remission. Rebora emphasizes the need for refined diagnostic criteria and treatment for AAI.
