- Abstract: BACKGROUND: Facial involvement of psoriasis is known to be one of the clinical manifestations that indicate the severity of the psoriasis and thought to be more closely associated with certain distribution. Centrofacial (CF) psoriasis has been suggested to be related with severity of systemic disease while peripherofacial (PF) psoriasis has been thought to have connection with scalp psoriasis. OBJECTIVE: To analyze the epidemiologic characteristics, clinical features and subjective feelings of patients with facial psoriasis and to find out relationship between scalp psoriasis and facial involvement according to the facial types. METHODS: One hundred nineteen facial psoriasis patients were categorized into 3 types according to the distribution: PF type, CF type and mixed facial (MF) type. Onset and duration of facial and scalp psoriasis, and their relationship were questioned. Severity and extent of psoriasis on whole body, face, and scalp were rated by clinicians. RESULTS: There was no significant difference of whole body psoriasis area and severity index (PASI) and body surface area (BSA) score but scalp PASI and BSA was much higher in PF psoriasis compared to CF psoriasis (scalp PASI, 17.9 vs. 10.1; p=0.005) (scalp BSA, 40.9 vs. 22.2; p=0.002). According to the questionnaire, patient's objective feeling about the spreading of scalp lesion to facial area was markedly more prominent in the patients with peripheral involvement (PF+MF, 90.1%; CF, 54.2%; p<0.0001). CONCLUSION: Among subtypes of facial psoriasis, PF psoriasis is closely associated with spreading of scalp lesion into the face rather than reflecting the disease severity.
