Melanoma occurrence under long-term etanercept treatment for psoriasis: a case report
Melanoma occurrence during treatment with anti-tumor necrosis factor is considered an incidental event, although very recent studies suggest a risk. Etanercept is a fusion protein that binds the tumor necrosis factor receptor and is included among TNF inhibitors, approved for the treatment of several autoimmune diseases, such as psoriasis.We described a 79-year-old man with psoriasis, being treated with etanercept, who presented with a new brown to black macule on his right shoulder; this was immediately surgically excised. Histology showed a superficial spreading melanoma, 1.2 mm Breslow thickness, one mitosis/hpf, with no vascular or neural invasion (stage T2b). Sentinel lymph node biopsy was negative. There were no apparent melanoma risk factors: normal total nevus count, photo type IV, no childhood sunburns, no family history of melanoma, and no previous immune suppressive drugs and/or phototherapies. Etanercept 50 mg/week had been administered continuously for 5 years before the melanoma occurrence. After etanercept withdrawal his psoriasis slowly, but progressively relapsed
Fatal hyalohyphomycosis with cutaneous involvement caused by purpureocillium lilacinum in an immunocompromised patient with bullous pemphigoid
Emergent pathogen as Purpureocillium lilacinum are becoming cause of morbidity and mortality in our population, especially in immunocompromised patients. We describe a case of hyalohyphomycosis in a diabetic man under systemic steroid treatment for a bullous pemphigoid. Treatment with different antimycotic drugs were ineffective and infection spread diffusely, leading to deterioration of general conditions and ultimately death. The aim of this article is to increase awareness of clinicians about this uncommon, but frequently fatal refractory mycotic infection
Agricultural use of copper and its link to Alzheimer’s disease
Copper is an essential nutrient for plants, animals, and humans because it is an indispensable component of several essential proteins and either lack or excess are harmful to human health. Recent studies revealed that the breakdown of the regulation of copper homeostasis could be associated with Alzheimer’s disease (AD), the most common form of dementia. Copper accumulation occurs in human aging and is thought to increase the risk of AD for individuals with a susceptibility to copper exposure. This review reports that one of the leading causes of copper accumulation in the environment and the human food chain is its use in agriculture as a plant protection product against numerous diseases, especially in organic production. In the past two decades, some countries and the EU have invested in research to reduce the reliance on copper. However, no single alternative able to replace copper has been identified. We suggest that agroecological approaches are urgently needed to design crop protection strategies based on the complementary actions of the wide variety of crop protection tools for disease control
Laser treatment monitoring with reflectance confocal microscopy
Laser treatments have become popular in Dermatology. In parallel to technologic development enabling the availability of different laser wavelengths, non-invasive skin imaging techniques, such as reflectance confocal microscopy (RCM), have been used to explore morphologic and qualitative skin characteristics. Specifically, RCM can be applied to cosmetically sensitive skin areas such as the face, without the need for skin biopsies. For these reasons, apart from its current use in skin cancer diagnosis, our systematic review reveals how RCM can be employed in the field of laser treatment monitoring, being particularly suitable for the evaluation of variations in epidermis and dermis, and pigmentary and vascular characteristics of the skin. This systematic review article aims to provide an overview on current applications of RCM laser treatment monitoring, while describing RCM features identified for different applications. Studies on human subjects treated with laser treatments, monitored with RCM, were included in the current systematic review. Five groups of treatments were identified and described: skin rejuvenation, scar tissue, pigmentary disorders, vascular disorders and other. Interestingly, RCM can assist treatments with lasers targeting all chromophores in the skin and exploiting laser induced optical breakdown. Treatment monitoring encompasses assessment at baseline and examination of changes after treatment, therefore revealing details in morphologic alterations underlying different skin conditions and mechanisms of actions of laser therapy, as well as objectify results after treatment
Angiomatoid giant cellular blue nevus of vaginal wall associated with pregnancy
<p>Abstract</p> <p>Background</p> <p>Blue nevi that arise from the Müllerian tract are rare melanocytic lesions. Several histopathologic variants of cellular blue nevi have been described. The angiomatoid variant is characterized by a vascular component, and is considered to be a rare variant. Few studies have explored the influence of pregnancy on melanocytic lesions.</p> <p>Case</p> <p>A 29-year-old woman was presented with a pigmented vaginal lesion that increased gradually during pregnancy. A full term gynecologic examination showed a tumor mass protruding into the vaginal canal. The mass was resected during cesarean-section under the clinical impression of vaginal hemangioma.</p> <p>Result</p> <p>Gross examination revealed a cystic mass measuring 6.0 × 4.3 × 3.5 cm, which was filled with dark friable material. Histologically, the mass showed a subepithelial cellular proliferation of heavily pigmented dendritic melanocytes with prominent vascular stroma. Cytologic pleomorphism, junctional activity, atypical mitosis, and necrosis were not found. The proliferation was immunoreactive for HMB-45, S-100 and melan-A, and non-immunoreactive for CD34, smooth muscle actin, and AE1/AE3. The MIB-1 proliferative index was less than 1%. The patient had a postoperative course without complication.</p> <p>Conclusions</p> <p>Angiomatoid giant cellular blue nevus arising from the vagina during pregnancy is extremely rare. The low proliferative index and absence of cytologic pleomorphism, or necrosis, supports a benign biological behavior. Clinical follow-up showed no evidence of recurrence at one year after the resection of the mass.</p
"Your Skin Tells You" Campaign for Keratinocyte Cancers: When Individuals' Selection Makes the Difference
Background: Prevention campaigns for skin cancers have focused primarily on melanoma, and over time there has been increasing awareness of the need to select the population to be screened to maximize program effectiveness. Objectives: The objective of the study was to report the results of a free dermatological initiative, as part of an awareness campaign dedicated to keratinocyte cancers, targeting individuals pre-selected through a short questionnaire. Methods: One day of dermatological consultations was held at 15 dermato-oncology referral centers during May 22-June 30, 2021. For selection, individuals answered a telephone interview consisting of 7 yes/no questions on risk factors. Demographics, clinical characteristics of suspicious tumors, and histopathologic diagnosis of excised lesions were collected. Suspicion rate, detection rate, and positive predictive values (PPVs) for any skin cancer, basal cell carcinoma (BCC), cutaneous squamous cell carcinoma (cSCC), and melanoma were calculated. Results: A total of 320 individuals (56.9% males; 43.1% females) with a median age of 69.6 (range 21-91) years qualified for the screening initiative. Overall, skin cancers and precancerous lesions were diagnosed in 65.9% of the patients. Suspicion rate was 28.7% for any skin cancer (92/320), 22.8% for BCC (73/320), 4.7% for cSCC (15/320), and 1.2% for melanoma (4/320). Detection rate was 23.4% for any skin cancer (PPV 93.7%), 18.1% for BCC (PPV 95.1%), 4.4% for cSCC (PPV 93.3%), and 0.9% for melanoma (PPV 75%). Conclusions: Selection of individuals at high risk is a cost-effective approach for early detection campaigns for keratinocyte cancers
Age and gender influence on HIDRAdisk outcomes in adalimumab-treated hidradenitis suppurativa patients
Background Hidradenitis suppurativa (HS) is a chronic relapsing inflammatory skin disease characterized by a significant impairment of patients' quality of life (QoL). It has been recently found that clinical severity of HS does not correlate well with QoL. Therefore, it is important to enhance the evaluation of severity considering the disease burden on QoL. Recently, a new graphical tool able to better describe HS burden, the so-called HIDRAdisk, has been introduced. Objective To investigate the utility of HIDRAdisk in clinical practice before and after treatment and to analyse whether specific factors such as age and gender may influence the outcomes in patients with moderate-to-severe HS. Methods A single-centre retrospective study on 24 patients (13F/11M, mean age 38 +/- 15 years) with moderate-to-severe HS was performed. Clinical data (disease severity and quality of life) were collected at baseline and after 12 weeks of adalimumab. Results HIDRAdisk showed significantly better improvements in males (69.8 +/- 6.2-49.6 +/- 10.8) compared to females (80.7 +/- 6.0-72.3 +/- 6.7), P <0.001. A significant correlation was found in the total population between HS severity values measured through the modified Sartorius score (mSS) and QoL measured through HIDRAdisk. As regards the relationship between disease outcomes and age, a trend for better HIDRAdisk outcomes in younger patients (<40 years) compared to older ones was observed. Conclusions HIDRAdisk appears as a complete and informative tool which can easily measure the global burden of HS, guiding treatment choice and evaluating its efficacy
Dupilumab therapy of atopic dermatitis of the elderly: a multi-centre, real-life study
Treatment of moderate-to-severe atopic dermatitis in the elderly may be challenging, due to side effects of traditional anti-inflammatory drugs and to comorbidities often found in this age group. Furthermore, efficacy and safety of innovative drugs such as dupilumab is not yet well known
