We describe a rhinofacial entomophthoramycosis case in a sexagenarian (65 years old) housewife. She was immunocompetent and resident of Burkina Faso. She consulted both the service of dermatology and the service of stomatology of the Teaching Hospital of Bobo-Dioulasso in February 2016 for a diffuse facial tumefaction evolving over six months. This tumefaction was associated with headaches and a left nasal obstruction. Histological examination of the lesion showed an important and polymorphic inflammatory reaction...

Histoplasmosis is the most common endemic mycoses among HIV-infected people. Patients with suppressed cell immunity mainly due to HIV are at increased risk of disseminated disease. Dermatological manifestations of immune reconstitution inflammatory syndrome (IRIS) and cutaneous manifestations of histoplasmosis similar to an IRIS event have been previously described. We report the case of a 43-year-old male who presented with cutaneous disseminated histoplasmosis due to Histoplasma capsulatum var. capsulatum 4 months after the onset of the antiretroviral therapy and some improvement in the immune reconstitution...

Dermatomyositis is a myopathic or amyopathic autoimmune connective tissue disease that presents with classic dermatologic findings ranging from: poikilodermatous photosensitivity (shawl sign), eyelid edema and violaceous-pigmentation (heliotrope sign), lichenoid eruptions on the knuckles and elbows (Gottron's sign), periungual telangiectasias, and ragged cuticles (Samitz sign). Up to 30 percent of adult-onset cases of dermatomyositis may represent a paraneoplastic syndrome warranting a thorough work-up for malignancy...

Cutaneous adverse drug reactions are among the most common noninfectious rashes of childhood. Cutaneous adverse drug reactions are classified as morbilliform, urticarial, bullous, pustular, or psoriasiform. Atopic dermatitis is one of the most common inflammatory cutaneous eruptions, and is characterized by pruritus and flexural distribution. Emollients and topical corticosteroids are first-line therapies. Topical calcineurin inhibitors are second-line, steroid-sparing drugs for certain conditions, such as face and eyelid eczema...

A substantial part of ongoing research in experimental dermatology focuses on skin T cells - for that reason we find important to highlight the pioneering work of Jan D. Bos et al. from 1987 (The skin immune system (SIS): Distribution and immunophenotype of lymphocyte subpopulations in normal skin). This key article set the record straight, once and for all, about the presence of lymphocytes in healthy skin; characterized the immunophenotypes of subpopulations, quantified these cells, and studied their location...

BACKGROUND: BIOREP is a Czech registry of psoriatic patients on biological treatment in a clinical setting. We describe the characteristics of patients with psoriasis at the time of enrollment and present comparisons with published data from other national registries. METHODS: We analyzed the cohort of patients treated with biologics between May 2005 and May 2015. Demographic data, previous therapies, comorbidities, and severity of psoriasis were compared with data from other registries - DERMBIO, BIOBADADERM, BADBIR, and PSOBEST...

Biological therapeutic therapies are gaining the attention of scientists and medical doctors. Accumulating evidence suggests that blood-derived autologous therapies are safe and effective treatments for skin repair and wound healing. The fibrin network formed after plasmatic activation and the autologous growth factors released when platelets degranulate constitute a real biological medicine that has been shown to promote cell recruitment, stimulate new blood vessel formation, reduce inflammation as well as protect from local infections...

BACKGROUND AND AIMS: Up till now the role of simeprevir plasma concentrations has not been described in treated patients affected by chronic hepatitis C and with dermatological side-effects. In this study, we have evaluated a possible relationship between plasma levels and the onset of skin complaints for the first time. METHODS: We report a clinical and pharmacokinetic analysis of 56 patients treated with simeprevir-based therapies. RESULTS: Simeprevir plasma concentrations were significantly related to dermatological side-effects at early time-points (P<0...

Kennedy and Pottier discovered that photodynamic therapy (PDT) could be carried out using a procedure consisting of topical application of the porphyrin-precursor, 5-aminolevulinic acid (ALA) to the skin, followed after some time by illumination with various light parameters in the 1980s. Since then, ALA-PDT has expanded enormously and now covers most aspects of dermatological disease. The purpose of this review is to discuss a range of ingenious strategies that investigators have devised for improving the overall outcome (higher efficiency and lower side effects) of ALA-PDT...

Angiogenesis is the growth of new blood vessels from pre-existing vessels. It is a biological process essential in physiological wound healing or pathological inflammation and tumor growth, which underlies a complex interplay of stimulating and inhibiting signals. Extracellular matrix, cells of innate and adaptive immunity and endothelial cells itself are a major source of angiogenic factors that activate or inhibit specific receptors and consequently influence intracellular signaling pathways. Most inflammatory and neoplastic diseases in dermatology are characterized by excessive angiogenesis, such as psoriasis, atopic dermatitis, as well as melanoma, non-melanoma skin cancer, but also benign vascular neoplasia...

PURPOSE: Lichen sclerosus (LS) is a chronic inflammatory skin condition that frequently involves the anogenital region. Ongoing research is focused on finding more effective treatments for tissue repair and reducing symptoms. The aim of this study is to evaluate the effectiveness of platelet-rich plasma (PRP) local injections in penile LS. METHODS: Forty-five male patients affected by penile LS underwent injections of autologous PRP in the affected skin areas. Age at diagnosis and at first treatment, number of treatments, clinical conditions (phimosis, splitting, inflammation, synechiae, meatus stenosis), symptoms (pain, burning, itching), and functional impairment were considered...

BACKGROUND: Expression of P2X7 , an ATP gated calcium channel, increases cancer cell proliferation and invasiveness. A variant of P2X7 (termed nfP2X7 ), in which a normally hidden epitope (E200) is exposed for antibody binding, is observed in a variety of different cancers. OBJECTIVES: To investigate the safety, tolerability and pharmacokinetics and assess indicative efficacy of a novel antibody ointment as a therapeutic for BCC. METHODS: An open label, Phase 1 clinical trial was undertaken at 3 dermatology clinics to evaluate the safety and tolerability of topical administration of an ointment containing 10% sheep polyclonal anti-nfP2X7 antibodies (BIL010t) to primary BCC lesions twice daily for 28 days...

Radiation recall dermatitis (RRD) is an inflammatory reaction in a previously irradiated field subsequent to the administration of pharmacologic or promoting agents. Herein, we describe a 47-year-old man with NSCLC who was treated with radiotherapy and pemetrexed-based chemotherapy three years prior to developing RRD upon resumption of pemetrexed-based chemotherapy. RRD with pemetrexed is rare and consists of five cases reported thus far. Although RRD is a rare phenomenon, it should be considered in any patient with dermatologic reactions that occur at the site of previous exposure to radiation therapy...

INTRODUCTION: Despite the large routine use of biologic drugs in psoriasis treatment, the majority of studies do not take into consideration dose-adjustment practice in "real life" dermatological setting. In routine clinical practice the disease management may include a large number of conditions requiring non-standard dosage regimens, including dose-escalation, dose-reduction and/or off-label treatment interruption. OBJECTIVE: The ONDA (Outcome of non-standard dosing regimen in Psoriasis and Psoriatic Arthritis) study aim was to retrospectively analyse dose-adjustment strategies among biologic therapies for psoriasis in dermatological practice during a 3-year period...

REVIEW
William Damsky, Brett A King
New molecularly targeted therapeutics are changing dermatologic therapy. Janus kinase-signal transducer and activator of transcription (JAK-STAT) is an intracellular signaling pathway upon which many different proinflammatory signaling pathways converge. Numerous inflammatory dermatoses are driven by soluble inflammatory mediators, which rely on JAK-STAT signaling, and inhibition of this pathway using JAK inhibitors might be a useful therapeutic strategy for these diseases. Growing evidence suggests that JAK inhibitors are efficacious in atopic dermatitis, alopecia areata, psoriasis, and vitiligo...

Immunotherapy targeting the programmed cell death 1 (PD-1) receptor has demonstrated tremendous promise in the treatment of advanced solid tumors. Dermatologic toxicities, however, are an emerging consequence of this therapy and have been clearly associated with immune checkpoint blockade antibodies. Distinctive clinical and histologic subtypes of dermatologic toxicity secondary to immunotherapy are emerging and include rare autoimmune bullous reactions (eg, bullous pemphigoid) and lichenoid eruptions. We report three patients who developed lichenoid dermatitis while receiving anti-PD-1 antibody therapy...
