Background: Skin psoriasis precedes the onset of psoriatic arthritis (PsA) in 84% of patients with psoriasis. Dermatologists have an important role to screen psoriasis patients for PsA. The efficiency of PsA screening remains unknown.

Introduction: Congenital hemangiomas (CHs) are rare congenital vascular tumors seldom mentioned in the literature.

Materials And Methods: We carried out a retrospective study of all the cases of CH diagnosed and treated at Besançon Hospital from 2008 to 2014. The clinical, radiological, and histological data of each case were collected.

As the detection of the BRAF V600E mutation has a direct impact on treatment decision, an accurate screening for BRAF mutations in patients with advanced or metastatic melanoma is mandatory. Nevertheless, BRAF oncogene mutation status between different samples from the same patient has been studied with conflicting results. This study investigated the intrapatient homogeneity of BRAF mutation status using pyrosequencing in primary tumors and different metastatic sites of melanoma patients.

Background: Systemic mastocytosis is characterised by abnormal proliferation of mast cells in various organs. We report an original case of systemic mastocytosis revealed by vulvar oedema.

Patients And Methods: A 24-year-old patient was examined in the dermatology department for vulvar oedema appearing during sexual intercourse.

Patients with inflammatory rheumatisms, such as rheumatoid arthritis, are more prone to develop skin cancers than the general population, with an additional increased incidence when receiving TNF blockers. There is therefore a need that physicians treating patients affected with inflammatory rheumatisms with TNF blockers recognize malignant skin lesions, requiring an urgent referral to the dermatologist and a potential withdrawal or modification of the immunomodulatory treatment. We aimed to demonstrate that an online training dedicated to skin tumors increase the abilities of rheumatologists to discriminate skin cancers from benign skin tumors.

Background: Human Papillomavirus (HPV) infection is known to be associated with a number of conditions including cervical, vaginal, vulvar, penile, anal neoplasias and cancers, oropharynx cancers and genitals warts (GW). Two prophylactic vaccines are currently available: a bivalent vaccine designed to prevent HPV type 16 and 18 infection and a quadrivalent vaccine targeting HPV 6, 11, 16, and 18. In France, HPV vaccination is recommended in 11-14 year-old girls with a catch-up for girls aged 15-19.

The prognostic value of the sentinel lymph node in Merkel cell carcinoma (MCC) has been examined previously in heterogeneous retrospective studies. The current retrospective study included a homogeneous population of patients with a localized MCC, all staged with sentinel lymph node biopsy. Factors associated with 3-year progression-free survival were analysed using logistic regression.

Background/aims: Merkel cell carcinoma (MCC) is a rare high-grade neuroendocrine tumour of the skin. It has been speculated that MCCs express somatostatin receptors (SSTRs), but this has never been assessed in a large series of MCCs. The main aim of this study was to assess the expression of SSTR2A and SSTR5 in MCC tumours.

Background: Dystrophic epidermolysis bullosa (DEB) is a genodermatosis characterized by various abnormalities of anchoring fibrils, composed mainly of type VII collagen, at the dermal-epidermal junction. These changes are induced by mutations in the type VII collagen gene (COL7A1).

Patients And Methods: A new-born boy was diagnosed with recessive DEB on the basis of typical skin lesions composed of multiple blisters with erosions on trauma-exposed body sites, including the hands and feet and the navel.

Background: Advances in neonatology have markedly improved prognosis for premature babies in recent years. However, they have also entailed the need for recourse to considerable intensive care involving potentially iatrogenic diagnostic and therapeutic acts. Among the resulting iatrogenic events, cutaneous lesions are the most frequent but have been the subject of very few studies.

Introduction: We present formulation and stability evaluation of a 2% (w/v) phenylephrine hydrochloride biocompatible eye drop solution, routinely prepared in hospital pharmacy under aseptic conditions, for retinal examination of neonates and premature infants.

Materials And Methods: Eye drop solution was formulated by dissolution of phenylephrine hydrochloride and disodium hydrogen phosphate as buffering agent in sterile water for injection and sodium chloride for injection as isotonic agent. The previous solution was sterile filtered through under aseptic conditions, in an iso class 5 air quality clean room under horizontal laminar airflow hood.

Background: CD20 is a B cell lineage-specific marker expressed by normal and leukemic B cells and targeted by several antibody immunotherapies. We have previously shown that the protein from a CD20 mRNA splice variant (D393-CD20) is expressed at various levels in leukemic B cells or lymphoma B cells but not in resting, sorted B cells from the peripheral blood of healthy donors.

Results: Western blot (WB) analysis of B malignancy primary samples showed additional CD20 signals.

Psoriasis involves TNF-α secretion leading to release of microparticles into the bloodstream. We investigated the effect of TNF blockers on microparticles levels before and after treatment in patients (twenty treated by anti-TNF-α agents and 6 by methotrexate) with severe psoriasis. Plasmatic microparticles were labelled using fluorescent monoclonal antibodies and were analysed using cytometry.

Erosive oral lichen planus (OLP) is a chronic, disabling mucocutaneous dysimmune rare disease characterized by mucosal inflammatory erosive lesions with pathological evidence for a marked CD8+ cytotoxic T-lymphocyte (CTL) infiltration. However, the specificity of lesional CTL in OLP has never been analyzed. To investigate the molecular mechanisms underlying dysregulation of T-cell immune responses in patients with OLP, we studied the diversity and antigen specificity of the TCR expressed by CD8+ T cells using dextramer staining, spectratyping, and TCR sequencing in 10 OLP patients undergoing extracorporeal photochemotherapy.

Psoriasis (Pso) is a common chronic cutaneous inflammatory disease involving the skin that is associated with serious comorbidities. Comorbidities in Pso include psoriatic arthritis (PsA), reduced quality of life, malignancy, depression, but also a constellation of associated conditions that enhance the cardiovascular (CV) risk. Indeed, obesity is common in patients with Pso or PsA and is considered to be a risk factor for the onset of these diseases.

Infantile myofibromatosis is a rare genetic disorder characterized by the development of benign tumors in the skin, muscle, bone, and viscera. The molecular pathogenesis is still incompletely known. An autosomal dominant form had been reported as causally related with mutations in the gene for platelet-derived growth factor receptor beta (PDGFRB).

Objectives: High risk human papilloma-viruses (HR HPV) are associated with risk of cervical dysplasia and carcinoma. The risk is increased in patients with immune deficiency or auto-immune disease as systemic lupus erythematosus. Currently, no data are available about the human papillomavirus status in women with systemic sclerosis (SSc).

Background: Retrospective data have suggested the effectiveness of intravenous immunoglobulins (IVIG) for solar urticaria (SU).

Objective: We sought to prospectively assess the efficacy of IVIG for SU.

Methods: We conducted a multicentric phase II study to test the efficacy of a single course of IVIG (2 g/kg) in patients with severe and refractory SU.

Background: Some international guidelines have been published to provide the best care for patients with psoriatic arthritis (PsA) but little is known about their quality.

Objective: The primary aim of this study was to examine the quality of guidelines that concern treatment (biotherapy exluded) of PsA. The secondary aim was to review studies published since the publication of the most recent guideline.

Background: Up to 29% of patients with psoriasis seen by dermatologists have undiagnosed psoriatic arthritis (PsA). As early detection of PsA may be associated with improved joint and skin outcomes, it is essential for dermatologists to improve their ability to diagnose PsA. Skin and nail features of psoriasis associated with PsA are well known to dermatologists but they may feel less confortable assessing other symptoms and they rarely use PsA screening questionnaires.
