Palmoplantar Psoriasis: Epidemiological and Clinical Features and Impact on Quality of Life.

INTRODUCTION: Palmoplantar psoriasis is a rare variant of psoriasis. Its impact on quality of life has been poorly investigated. OBJECTIVES: Our aim was to investigate the prevalence of localized palmoplantar psoriasis (PPP), to assess its severity using the modified Palmoplantar Pustular Psoriasis Area and Severity Index (m-PPPASI), and to evaluate the correlation with the Dermatology Life Quality Index (DLQI). METHODS: We conducted a descriptive study with prospective data collection from January to June 2021. We enrolled 223 patients with psoriasis. We excluded patients without palmar/plantar involvement and those with a body surface area (BSA) greater than or equal to 10%. RESULTS: We included 33 patients with PPP. This corresponded to a 14.8% prevalence among all psoriasis phenotypes. The mean age was 45 years. The male-to-female ratio was 2.3. Pruritus was present in 27 cases. The mean m-PPPASI was 11.77. The mean DLQI was 8.33. A significant correlation was found between DLQI and m-PPPASI: mean DLQI scores for patients with m-PPPASI less than or equal to 10 and m-PPPASI greater than 10 were 5.6 and 11.3, respectively (P = 0.002). Only 11.8% of patients with m-PPPASI less than or equal to 10 had a DLQI greater than 10, whereas 50% of those with m-PPPASI greater than 10 had a DLQI greater than 10 (P = 0.026). CONCLUSIONS: Based on the present work, we confirm that, although affecting a reduced BSA, PPP is a severe form of psoriasis. We consider the m-PPPASI to be a reliable tool which can be used to assess the severity of PPP.

Inflammatory Tinea Capitis Mimicking Dissecting Cellulitis in a Healthy Woman.

Introduction: Inflammatory tinea capitis (TC) is uncommon in adults. Case Presentation: A 29-year-old healthy woman presented with a 2-year history of scalp alopecia with purulent discharge. Clinical, trichoscopic, and histological features and the negativity of a first fungal sampling were consistent with the diagnosis of dissecting cellulitis of the scalp. A second mycological examination guided by trichoscopy was carried out, showing tinea endothrix. Fungal culture isolated trichophyton violaceum. The patient was treated with terbinafine with complete healing. Conclusion: The diagnosis of adult TC is challenging, mainly the inflammatory form. An exhaustive trichoscopic examination of all alopecic plaques may help make a rapid diagnosis and provide a guide to the mycological examination.

Localized scleroderma with pulmonary arterial hypertension and pulmonary interstitial fibrosis in a patient with positive Th/to antibodies: Case report and review of literature.

Morphea is an auto-immune disease, and its association with other immune-mediated diseases should not come as a surprise. Dermatologists should be aware of its possible coexistence with severe systemic involvement.

Extensive keloid scarring in a patient with pemphigus vulgaris.

Since pemphigus blisters are intraepidermal, scarring should induce at most a post-inflammatory hyperpigmentation. We describe a very atypical and unusual course of pemphigus vulgaris with extensive keloid formation despite high systemic steroids. This could be promoted by the severe flare of the disease, the delay of scarring, and the superinfection.

Confluent and reticulated papillomatosis of Gougerot-Carteaud in a North African patient.

Confluent and reticulated papillomatosis (CRP) is an underdiagnosed skin condition of uncertain etiology. The antibacterial and most importantly the anti-inflammatory mechanisms of some antibiotics seem to explain the effectiveness of these medications. Other measures such as reducing weight and treating an underlying endocrine disorder may be helpful.
