Relation between the Peripherofacial Psoriasis and Scalp Psoriasis

Area of Science:

• Dermatology
• Clinical Research
• Psoriasis Epidemiology

Background:

• Facial psoriasis is a marker of psoriasis severity.
• Psoriasis distribution on the face may correlate with disease characteristics.
• Centrofacial (CF) psoriasis may relate to systemic disease severity, while peripherofacial (PF) psoriasis might connect to scalp psoriasis.

Purpose of the Study:

• Analyze epidemiologic and clinical features of facial psoriasis.
• Investigate patient-reported subjective feelings.
• Determine the relationship between scalp and facial psoriasis based on facial subtype.

Main Methods:

• 119 facial psoriasis patients classified into PF, CF, and mixed facial (MF) types.
• Questionnaires assessed onset, duration, and relationship between facial and scalp psoriasis.
• Clinicians evaluated psoriasis severity and extent on the body, face, and scalp.

Main Results:

• No significant difference in whole-body Psoriasis Area and Severity Index (PASI) or Body Surface Area (BSA).
• Scalp PASI and BSA were significantly higher in PF psoriasis compared to CF psoriasis.
• Patients with peripheral involvement (PF+MF) reported greater perceived scalp-to-face lesion spread than CF patients.

Conclusions:

• Peripherofacial (PF) psoriasis is associated with scalp psoriasis spreading to the face.
• This association in PF psoriasis relates more to lesion spread than overall disease severity.
