Cephalalgia Alopecia or Nummular Headache With Trophic Changes? A New Case With Prolonged Follow-Up

The document described a case of a 33-year-old woman experiencing continuous unilateral occipital pain accompanied by localized hair loss, a condition referred to as cephalalgia alopecia. This rare headache syndrome involved recurrent, burning pain in the head and neck, with hair loss in the affected areas. The patient's symptoms were only responsive to onabotulinumtoxin A injections. The authors discussed whether this condition might be cephalalgia alopecia or nummular headache with trophic changes, suggesting these could be different manifestations of the same disorder spectrum.
