Koilonychia in a Patient with Alopecia Areata

The document reported a case of a 25-year-old female with alopecia areata (AA) and koilonychia, a rare nail dystrophy characterized by spoon-shaped nails. AA is an autoimmune condition affecting hair follicles, often accompanied by nail changes due to lymphocytic inflammation. Koilonychia is typically linked to iron deficiency and inflammatory skin conditions but is rarely associated with AA. In this case, the patient's koilonychia regressed almost completely after treatment with oral corticosteroids. The report discussed the pathogenesis and potential prognostic significance of koilonychia in the context of AA.
