Study of the Characteristics of Pruritus in Patients With Frontal Fibrosing Alopecia or Lichen Planus Pilaris

Study of the Characteristics of Pruritus in Patients With Frontal Fibrosing Alopecia or Lichen Planus Pilaris

The prevalence of pruritus has been studied in frontal fibrosis alopecia (FFA) and lichen planus pilaris (LPP), but there are no studies evaluating the characteristics of pruritus, the correlation between pruritus and disease activity, and its impact on quality of life.

The knowledge of the characteristics of pruritus, of the link "disease activity - pruritus", and its impact on the quality of life could allow us to modify the management of the patient (modification or intensification of therapy, close monitoring...)

Inclusion Criteria:

• Major patient.
• Fibrosing frontal alopecia or lichen planus pilaris
• Presence of pruritus of the scalp : a positive response to the question "do you experience itchy scalp?"
• The patient received an information note and did not object to the study

Exclusion Criteria:

• Patients under 18 years of age.
• Other pathologies causing scalp pruritus (seborrheic dermatitis, contact dermatitis, lupus, Quinquaud's decalcifying folliculitis, ectoparasitosis, scalp psoriasis, ringworm, red sclap syndrome, dermatomyositis, central centrifugal cicatricial alopecia (CCCA))
• Refusal to participate by the patient.
• Patient under legal protection (curatorship, guardianship, ...)
• Patient not covered by social security
