We present the case of a 73-year-old-woman, admitted in 2014 for n erysipelas of the face (figure 1a) beginning 3 days before, with red oedematous papules of the left temple, hyperthermia and chills the day after. Clinical examination did not find lymphadenopathy or skin lesion especially at her left ear. Blood samples showed a raised C reactive protein (CRP) to 120 mg/L without leukocytosis. Antinuclear antibodies were negative. Viral serologies (HIV, hepatitis C and B, EBV, parvovirus B19, VZV, mumps), viral PCR assay (EBV, parvovirus B19, CMV, VZV) and bacterial blood cultures were all negative Histopathological findings revealed a reactive infiltrate without vasculitis and necrosis.

patients with moderate to severe psoriasis are difficult to treat with topical therapy only and they usually require additional systemic therapy. Despite this, a significant percentage of patients on these therapies shows an inadequate response to these drugs. Treatment decisions are often difficult as they usually rely on subjective terms. Therefore, finding indicators that predict efectiveness or failure to classical systemic therapy is an urgent need. The objective of this study was to analyse whether the phenotype of peripheral blood mononuclear cells (PBMC) would be different in responder or non-responder patients to classical systemic therapy, and thus could be used as a efectiveness predictor of this therapy effectiveness. These predictor markers could help physicians to choose the best individualised treatment for psoriasis patients.

In addition to the extent of atypical keratinocytes throughout the epidermis, actinic keratoses (AKs) are histologically characterized by downward directed basal layer expansion. It is not known if this growth pattern correlates with the risk of developing invasive squamous cell carcinoma (iSCC).
To characterize the prevalence of downward directed basal layer expansion of AKs adjacent to iSCC.
The epidermis overlying and adjacent to iSCCs was assessed histologically. We determined the histological grade (AKI-III), basal growth pattern (PROI-III) and accompanying parameters such as adnexal involvement.
Of 307 lesions, 52.4% of AKs were histologically classified as AKI, 38.1% as AKII, and 6.8% as AKIII (chi-squared; P<0.0001). 2.6% of adjacent epidermis did not show any atypical keratinocytes. The epidermis adjacent to iSCCs was classified as having a PROI basal growth pattern in 25.7%, PROII in 31.9%, and PROIII in 39.4% cases. 2.9% of AKs showed no basal growth (chi-squared; P<0.0001).118 (48.8%) AKs showed extension into adnexal structures. These AKs were graded as PROI in 18.6%, PROII in 30.5%, and PROIII in 50.8%. The epidermis above iSCCs could only be assessed for upwards directed growth and showed no significant differences in the three AK grades (P=0.4211).
Basal proliferative AKs as well as atypical keratinocytes restricted to the lower third of the epidermis are most commonly seen adjacent to iSCC with less evidence for full thickness epidermal dysplasia. Our study supports the important role of dysplastic keratinocytes in the epidermal basal layer and their potential association with iSCC.

Our knowledge of Eosinophilic fasciitis (EF), also known as Shulman's syndrome, is limited, and its prevalence has not been estimated so far. We conducted a regional survey which aimed at estimating the prevalence of EF in Alsace, a Region in the North-East of France. We retrospectively collected EF cases from the first of January 1983 to the 30th of March 2015 among Alsace residents aged >18 years, then performed a capture-recapture analysis with the prevalent cases in 2015.
