[Successful treatment of alopecia totalis with tofacitinib in a Danish patient].

Alopecia totalis (AT) is characterised by extensive hair loss on the scalp, and common treatments are rarely effective. Janus kinase inhibitors represent a potentially new treatment modality in AT. In this case report, AT was successfully treated with tofacitinib in a 43-year-old male patient. After six months of treatment, the patient regained all his hair, and no relapse was seen after one year of treatment.
