Relation between the Peripherofacial Psoriasis and Scalp Psoriasis

Abstract

BackgroundFacial 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.ObjectiveTo 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.MethodsOne 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.ResultsThere 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).ConclusionAmong subtypes of facial psoriasis, PF psoriasis is closely associated with spreading of scalp lesion into the face rather than reflecting the disease severity.

Sociodemographic, clinical and therapeutic factors as predictors of life quality impairment in psoriasis: A cross‐sectional study in Italy

“…Although the scalp, trunk and extremities are the most commonly affected areas, the involvement of face, palmoplantar and intertriginous regions have a significant impact on QoL 23,24 . About one in five patients with plaque psoriasis has facial involvement, and the latter is more common in patients with longer disease duration, family history of psoriasis, and more severe psoriasis 25–28 . Approximately, 20%–30% of psoriatic patients have an inverse (intertriginous) involvement affecting inframammary, axillary, inguinal, intergluteal, or other skin folds 23 .…”

“…23,24 About one in five patients with plaque psoriasis has facial involvement, and the latter is more common in patients with longer disease duration, family history of psoriasis, and more severe psoriasis. [25][26][27][28] Approximately, 20%-30% of psoriatic patients have an inverse (intertriginous) involvement affecting inframammary, axillary, inguinal, intergluteal, or other skin folds. 23 Here, the prevalence of psoriasis in facial and intertriginous regions was 10.9% and 9%, respectively.…”

Fingernail Involvement is a Bigger Burden Than Face and Scalp Involvement in Patients With Psoriasis

“…Highly visible lesions, such as those on the scalp, face, and fingernails, are big burden for patients with psoriasis. [1][2][3][4][5] However, limited real-world data are available regarding this subject. We retrospectively evaluated the association of Dermatology Life Quality Index (DLQI) with psoriasis lesions on the scalp, face, and fingernails and assessed the impact of these lesions on the patients.…”
