A Long-Term Follow-Up of Angiolymphoid Hyperplasia with Eosinophilia Treated by Corticosteroids: When a Traditional Therapy is Still Up-to-Date

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare and idiopathic vascular disorder. It is characterized by red to brown papules or nodules dislocated in the dermis or subcutaneous tissue. These lesions are typically localized on the head and neck, particularly around the ear as singular or multiple nodules. Although ALHE is a benign disease, lesions are often persistent and difficult to eradicate. ALHE can occur in all races, but it is reported more frequently in Asians. Young to middle-aged women are more commonly affected. The histological examination corresponds to a florid vascular proliferation with atypical endothelial cells surrounded by a lymphocytic and eosinophilic infiltrate. We describe the case of a 67-year-old Caucasian man with a nodular lesion in the right postauricular region for 3 years. The histological examination was consistent with ALHE. Monthly intralesional corticosteroid injections were performed for 6 months, and complete remission was achieved. After 10 years of follow-up, the patient is free of recurrence

Fohotodermatoses and Skin Cancer

Preface Skin cancer is one of the most common types of tumors in Western countries. In the United States only, more than one million people are diagnosed with skin cancer each year. Although the absolute number of skin cancer patients is increasing, the death is inversely decreasing, due to the early detection and treatment. Basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma are three major types of skin cancer. BCC and SCC rarely have metastasis; over 95 percent BCC and SCC patients can be cured. Melanoma only accounts for a small percentage of skin cancer, but it causes 75 percent death of this disease. In this book, we invited a number of experts to present their latest accomplishments on skin cancer research. Although the topics are varied, the authors did great work to help readers better understand skin cancer and learn the knowledge to prevent this disease. There are three sections in this book, starting with etiology. Ultraviolet (UV) light exposure is overwhelmingly believed to be the most frequent cause of skin cancer. In this section, the association between UV and photodermatoses, as well as skin cancer is discussed. Desmosomal cadherins are important molecules in tumor cell adhesion and invasion, and their important roles in BCC are also presented in details. In the diagnosis and treatment section, a few new methodologies are described. As known, the outcome of malignant melanoma greatly depends on the thickness of the tumor at the time of treatment. Accurate determination of melanoma lateral and depth of margins using non-invasive imaging technologies is of importance when making sound decisions for treatment and evaluating a five year survival rate. A novel method named differential scanning calorimetry is capable of predicting metastasis of melanoma patients by monitoring the temperature changes of plasma. Electronic miniature X-ray brachytherapy is introduced as a new technology to treat nonmelanoms skin cancer. Although its potential has not yet been fully realized, chemoprevention, in terms of using chemical agents that naturally occur in foods, or are administered as pharmaceuticals to retard or reverse the process of carcinogenesis and progression of cancer, has been recognized to benefit individuals with precancerous lesions or genetic susceptibilities to cancer. In the prevention section, two chapters summarized the most recognized dietary phytochemicals and their potential application in skin cancer. X Preface This book would not have been possible without the contributions of all authors and the support from the publisher. Especially, I will convey my sincere appreciation to Ms. Tajana Jevtic, who has always been available and supportive of me to accomplish this project.

Psoriatic Disease and Tuberculosis Nowadays

Psoriasis is a chronic, relapsing and remitting inflammatory skin and joint disease that has a prevalence of 2-3% in the world's population, whereas of 1–2% in Europe. The traditional concept of psoriasis as the “healthy people's” disease has been recently revised because of ever-increasing reports of associations with various pathological conditions (hypertension, Crohn's disease, type II diabetes mellitus, obesity, dyslipidemia, metabolic syndrome, infectious conditions). Particularly, advances in psoriasis therapies have introduced biologic agents. All the tumor necrosis factor-alpha inhibitors are associated with an increased risk of developing active disease in patients with latent tuberculosis infection, because of TNF-α key role against Mycobacterium tuberculosis. For this reason, exclusion of active tuberculosis and treatment of latent tuberculosis infection are clinical imperatives prior to starting this therapy. Moreover active surveillance for a history of untreated or partially treated tuberculosis or latent form has already been shown to be effective in reducing the number of incident tuberculosis cases

An Italian multicentre study on adult atopic dermatitis: persistent versus adult-onset disease.

Atopic dermatitis (AD) is a chronic, recurrent, inflammatory skin disease which predominantly affects children. However, AD may persist until adulthood (persistent AD), or directly start in adults (adult-onset AD). AD often shows a non-flexural rash distribution, and atypical morphologic variants in adults and specific diagnostic criteria are lacking. Moreover, adult AD prevalence as well as detailed data which can characterize persistent vs adult-onset subtype are scant. The aim of this study was to investigate on the main features of adult AD particularly highlighting differences between persistent vs adult-onset form. An Italian multicentre observational study was conducted between April 2015-July 2016 through a study-specific digital database. 253 adult AD patients were enrolled. Familiar history of AD was negative in 81.0%. Erythemato-desquamative pattern was the most frequent clinical presentation (74.3%). Flexural surface of upper limbs was most commonly involved (47.8%), followed by eyelid/periocular area (37.9%), hands (37.2%), and neck (32%). Hypertension (7.1%) and thyroiditis (4.3%) were the most frequent comorbidities. A subgroup analysis between persistent (59.7%) vs adult-onset AD patients (40.3%) showed significant results only regarding AD severity (severe disease was more common in persistent group, p < 0.05), itch intensity (higher in adult-onset disease), and comorbidities (hypertension was more frequent in adult-onset group, p < 0.01). Adult AD showed uncommon features such as significant association with negative AD family history and lacking of association with systemic comorbidities respect to general population. No significant differences among persistent vs adult-onset subgroup were registered except for hypertension, itch intensity, and disease severity

Minimal disease activity in patients with psoriatic arthritis treated with ustekinumab: results from a 24-week real-world study

Psoriatic arthritis (PsA) is a chronic inflammatory joint disease affecting around 40% of psoriasis patients. Minimal disease activity (MDA) criteria have been proposed to identify a state of low disease activity, one of the principal goals of treatment for psoriatic disease. This study investigated treatment with ustekinumab (UST) in the context of a real-world setting. Thirty-four PsA patients who had failure or inadequate response to conventional synthetic disease-modifying antirheumatic drugs or to anti-tumour necrosis factor alpha were enrolled. Demographic and clinical features, MDA criteria, and the impact of psoriatic skin manifestations on patients' quality of life (QoL) using the dermatology life quality index (DLQI) questionnaire were evaluated at baseline and after 24-week treatment. Adverse events were recorded. At week 24, 70.5% of patients (n = 24) achieved MDA. A sub-analysis of dermatological indices of the MDA criteria showed that the psoriasis area severity index score was significantly improved and body surface area was significantly decreased at 24 weeks compared with that at baseline (both p < 0.001). For the rheumatologic indexes, tender joint count, swollen joint count, and tender entheseal points were all significantly improved at 24 weeks of therapy (all p < 0.01 vs. baseline). Mean DLQI value decreased approximately fourfold, and there were no safety concerns. The achievement of MDA as well as the significant improvement in DLQI and lack of adverse events in the context of a real-life setting shown here confirms the efficacy and safety of UST in PsA

Zoon's Balanitis: Benign or Premalignant Lesion?

Zoon's balanitis or balanitis circumscripta plasmacellularis is a chronic disease of unknown origin. This condition usually manifests in middle-aged or elderly uncircumcised men. Although of unknown etiology, different factors have been reported to be involved in its genesis (local infections, poor hygiene, heat, friction, and constant rubbing). It is generally considered to be a benign condition, and its association with malignancies has been rarely reported. We report the case of an uncircumcised man, who developed clinically and histopathologically evident squamous cell carcinoma of the penis in an area affected by Zoon's balanitis
