Abstract: Erythrodermic psoriasis (EP) is a severe and rare variant of psoriasis, accounting for less than 3% of cases. It is characterized by widespread scaling and erythema that affects more than 90% of the body surface area. Alopecia can manifest as a symptom associated with the disease, further exacerbating the impact on the patient’s quality of life. We present the case of a patient with severe EP and diffuse alopecia who did not respond to conventional therapies. The patient was subsequently treated with ixekizumab as per labeled usage, resulting in complete resolution of both psoriatic skin lesions (Psoriasis area and severity index/PASI 100) and alopecia (The Severity of Alopecia Tool/SALT 0).

Keywords: erythrodermic psoriasis, alopecia, ixekizumab
