Psoriasis is a common chronic inflammatory skin disorder that primarily affects the skin, nails, and joints. Beyond its cutaneous manifestations, psoriasis is associated with several systemic comorbidities. Various factors can trigger or exacerbate psoriasis, including stress, infections, medications, and vaccinations. This article reports what is, to the best of the author's knowledge, the first known case of acute exacerbation of plaque-type psoriasis, presenting as guttate psoriasis (GP), following herpes zoster vaccination. A 52-year-old male with a history of longstanding plaque-type psoriasis developed a sudden flare of GP lesions 2 weeks after receiving the recombinant herpes zoster vaccine. Physicians should be vigilant for potential triggers of psoriasis exacerbation, with the recombinant herpes zoster vaccine being among them.

Introduction: Idiopathic guttate hypomelanosis (IGH) is a common leukodermic dermatosis that primarily affects middle-aged and elderly adults. This study evaluates the dermoscopic features of IGH and their correlation with histopathological findings.
Methods: In the present study, 100 patients with IGH were evaluated. Each patient underwent a comprehensive clinical history assessment along with a dermatological and physical examination. Dermoscopic examination was performed, followed by a histopathological examination to confirm the diagnosis.
Results: The mean age of the participants was 64.67 ± 9.59 years, with 53% being male. The most prevalent dermoscopic pattern observed was nebuloid (33.3%), followed by petaloid (26.7%), and both amoeboid and feathery patterns were seen in equal proportions (20% each). The abdomen (33%) and legs (27%) were the most common sites for IGH lesions. Histopathological examination revealed features such as basket weave hyperkeratosis, atrophic epidermis in some lesions, reduced melanin globules or melanocytes, skip lesions, and flattening of rete ridges across all dermoscopic patterns.
Conclusion: IGH is characterized by distinct dermoscopic patterns, including amoeboid, feathery, nebuloid, and petaloid types. When these patterns are interpreted within the clinical context and corroborated with histopathological findings, they aid in the accurate diagnosis of IGH and its differentiation from other hypopigmented and depigmented dermatoses. Dermoscopy can be considered an adjunctive tool to confirm the diagnosis of IGH.

Actinic lichen planus (ALP) is a rare photosensitive subtype of lichen planus (LP) with four major forms recognized: annular, pigmented (melasma-like), dyschromic, and classic lichenoid. The prevalence is highest among dark-skinned younger females residing in tropical and subtropical regions. There are very few reports of ALP across Europe, with most of the cases among individuals living in warm countries or in people of Middle Eastern and Indian ancestry. We report a case of a 68-year-old white man that presented with a 9-year history of a mildly pruritic solitary hyperpigmented patch on the tip of his nose. Histopathological examination demonstrated signs of classic LP with epidermal atrophy, pigmentary incontinence, and signs of solar elastosis. Based on these findings, a diagnosis of pigmented ALP was established. Topical pimecrolimus and tretinoin along with rigorous photoprotection proved effective, with mild residual hyperpigmentation after 6 months of treatment. Many differential diagnostic possibilities should be considered for such a lesion. Nevertheless, a biopsy and correlation of histopathological and clinical findings can shorten the time from onset to a proper diagnosis. Treating both the hyperpigmented and inflammatory component of this dermatosis is necessary, as well as strict long-term photoprotection to prevent recurrences.
日光性扁平苔藓(ALP)是扁平苔藓(LP)中一种罕见的光敏性亚型,主要有四种类型:环状型、色素沉着型(黄褐斑样)、色素失调型和典型苔癣型。居住在热带和亚热带地区的黑皮肤年轻女性发病率最高。欧洲有关 ALP 的报道很少,大多数病例都是生活在温暖国家的人或有中东和印度血统的人。我们报告了一例 68 岁的白人男性病例,他的鼻尖出现轻度瘙痒的单发色素沉着斑已有 9 年病史。组织病理学检查显示了典型的 LP 征,伴有表皮萎缩、色素失禁和日光性松弛症。根据这些检查结果,确定了色素性 ALP 的诊断。外用吡美莫司和曲安奈德以及严格的光防护证明是有效的,治疗 6 个月后,色素沉着仍有轻度残留。对于这种病变,应考虑许多鉴别诊断的可能性。不过,活组织检查和组织病理学与临床结果的相关性可以缩短从发病到确诊的时间。有必要同时治疗这种皮肤病的色素沉着和炎症部分,并进行严格的长期光防护以防止复发。

Recessive dystrophic epidermolysis bullosa (RDEB) is a rare genetic skin disease caused by mutations in the type VII collagen gene (COL7A1; 3p21.31). Mutations in this gene lead to an alteration in function or reduced amounts of collagen VII. This alteration of collagen VII leads to skin fragility and lesions at minor injuries with difficult healing. Cutaneous squamous cell carcinoma (cSCC) is more frequent in patients with RDEB than in the general population because of chronic wound formation; it constitutes a major cause of morbidity and is often cited as a cause of death for these patients. There is little experience with the treatment of cSCC in patients with RDEB. We report the case of a 19-year-old female patient with RDBE and inoperable locally advanced cSCC of the left arm. Because of the lack of therapy options, therapy with cemiplimab was started at a dose of 350 mg administered intravenously every 3 weeks. A confirmed clinical response was observed after the second cycle of treatment with no toxicity. During follow-up, the patient had a notable clinical response with no auto-immune adverse reactions. This shows that cemiplimab has a good safety profile for cSCC in patients with RDEB and is a valuable therapy option.

Introduction: Cellulite, also known as edematous fibrosclerotic panniculopathy (EFP), affects up to 90% of women and has a significant aesthetic impact. EFP is a multifactorial condition characterized by local circulatory changes, increased adipose tissue thickness, and a fibrotic response involving thick collagen bundles and septa, driven by local hypoxia. Although numerous treatments exist, their effects are typically temporary. This study evaluates the outcomes of four patients with EFP treated using a combined recombinant enzymatic therapy consisting of a lyase, lipase, and collagenase.
Methods: A standardized protocol involving injections of a combined enzyme solution (pbserum Medium™) was administered to the lower limbs in three separate sessions. Pre- and post-treatment photographs were collected for comparative analysis.
Results: All four patients showed improvements in skin appearance and fibrosis, with no systemic or local adverse events reported.
Conclusions: We propose that a treatment strategy targeting the edematous, adipose, and fibrotic components of EFP may offer an economical and pathogenic-based approach for managing this condition in affected women.

Introduction: Vitiligo is a prevalent skin disorder characterized by the destruction of melanocytes, leading to depigmented patches across various areas of the body. Interleukin (IL)-31 has been implicated in the development of pruritus and skin inflammation, potentially contributing to cutaneous symptoms. This study measures IL-31 levels in vitiligo patients with and without pruritus, comparing them to healthy controls, and explores the relationship between IL-31 levels, disease activity, and other clinical factors to assess its potential role in the early diagnosis of vitiligo.
Methods: Ninety individuals were enrolled in the study and equally divided into three groups: vitiligo, vitiligo with pruritus, and healthy controls. The serum level of IL-31 was measured using the enzyme-linked immunosorbent assay (ELISA).
Results: Significant differences in IL-31 levels were observed across all groups. IL-31 levels were highest in vitiligo patients with pruritus, followed by those without pruritus, and lowest in healthy controls, with mean values and standard deviations of 196 ± 67.28, 152.10 ± 74.39, and 80.03 ± 32.30 pg/ml, respectively. In addition, IL-31 levels in serum showed significant differences in relation to disease activity in both vitiligo groups. Positive correlations were found between IL-31 levels and the Vitiligo Area Scoring Index (VASI) and Vitiligo Disease Activity (VIDA) in both patient groups, as well as between IL-31 levels and lesion extent in vitiligo patients without pruritus. In patients with pruritus, IL-31 levels also positively correlated with age and the 5-dimension itch scale score.
Conclusion: IL-31 may serve as a crucial marker and play a significant role in the early diagnosis of vitiligo in patients both with and without pruritus.

Idiopathic acquired true leukonychia is a rare benign acquired disorder that typically affects adults. Diagnosis is made clinically, with investigations required to exclude any underlying cause. The cause of this condition is largely unknown, yet it understandably causes significant anxiety to patients due to concerns about underlying systemic disease. We report a case of idiopathic acquired true leukonychia totalis in a healthy 20-year-old man. Intermittent complete whitening of some of the fingernails was reported over a 7-year period. No underlying medical cause or laboratory abnormality was identified. This case highlights the importance of considering idiopathic acquired true leukonychia as a differential diagnosis of nail whitening. In addition, increased awareness of this unique entity is needed for patient reassurance, as well as avoidance of unnecessary investigations and prolonged systemic treatment.

Actinic granuloma (AG) is a rare dermatological condition with only a few dozen cases reported worldwide. Initially classified as a variant of granuloma annulare, it is now recognized as a distinct entity characterized by asymptomatic annular plaques in sun-exposed areas of the skin. The exact pathogenesis remains unclear, but it is believed to be an inflammatory response to sun damage, possibly involving injured elastic fibers. Numerous local and systemic therapeutic options exist, but no specific treatment guidelines have been established. We present a case of AG treated with intralesional application of triamcinolone acetonide in a 64-year-old male patient. We also discuss the most important clinical and histological characteristics and various treatment options.

Introduction: Skin cancer, a significant global health issue, requires prompt detection and management, particularly among the elderly. Primary care physicians play a critical role in early diagnosis because they are often the first to evaluate patients with skin lesions. Accurate diagnosis by family physicians is essential for effective treatment and improved patient outcomes.
Methods: Over a 12-year period, this study analyzed 125 samples from 89 patients that presented with visible skin changes or suspicious lesions identified during routine examinations. Initial working diagnoses made by family physicians were compared to final pathohistological diagnoses (PHD).
Results: The study found a significant difference between working diagnoses and final PHDs for malignant versus benign cases, with an accuracy of 83.3% and statistical significance (p = 0.04). A difference of 12.9% was observed, indicating areas for improvement. The diagnostic effectiveness for premalignant versus benign cases is high (accuracy of 88.2%), but without statistical significance (p = 0.50), and it suggests that these differences are not clinically relevant.
Conclusions: Primary care physicians demonstrate high accuracy in identifying malignant skin conditions, which is crucial for effective skin cancer management. However, improving diagnostic accuracy, particularly to reduce the misclassification of benign conditions as malignant, remains necessary. Continued training and development are essential to further enhance diagnostic precision for all skin conditions.

Beta defensins (β-defensins) are peptides primarily produced by epithelial cells in mammals to safeguard the skin, other organs, and mucosa from microbial colonization. These peptides are generated by epithelial cells, keratinocytes, and macrophages, mainly in response to interactions with microorganisms (bacteria, viruses, and fungi) or the influence of various pro-inflammatory cytokines. Human β-defensin (HBD) 2 plays an indirect role in allergic reactions by promoting mast cell activation and degranulation. In dermatological and allergic conditions, the role of HBD2 has been well documented. Although HBD2 is predominantly produced in keratinocytes, along with HBD3 it has also been detected in serum. Elevated serum levels of HBD2 have been observed in patients with skin diseases such as atopic dermatitis and psoriasis. In addition, HBD2 is significant in chronic spontaneous urticaria (CSU), in which urticarial skin lesions can be triggered by infections. Notably, CSU is often accompanied by angioedema, which may be related to HBD2 because patients with CSU and associated angioedema have higher serum HBD2 levels compared to those without angioedema. Current evidence suggests that HBD2 could serve as a marker of inflammation and may have potential therapeutic applications. However, due to limited data on HBD2 levels and its expression in the skin of patients with allergic skin diseases, further research is needed to elucidate the underlying causes and mechanisms of elevated HBD2 levels in these conditions.

These peptides are generated by epithelial cells, keratinocytes, and macrophages, mainly in response to interactions with microorganisms (bacteria, viruses, and fungi) or the influence of various pro-inflammatory cytokines. Human β-defensin (HBD) 2 plays an indirect role in allergic reactions by promoting mast cell activation and degranulation. In dermatological and allergic conditions, the role of HBD2 has been well documented. Although HBD2 is predominantly produced in keratinocytes, along with HBD3 it has also been detected in serum. Elevated serum levels of HBD2 have been observed in patients with skin diseases such as atopic dermatitis and psoriasis. In addition, HBD2 is significant in chronic spontaneous urticaria (CSU), in which urticarial skin lesions can be triggered by infections. Notably, CSU is often accompanied by angioedema, which may be related to HBD2 because patients with CSU and associated angioedema have higher serum HBD2 levels compared to those without angioedema. Current evidence suggests that HBD2 could serve as a marker of inflammation and may have potential therapeutic applications. However, due to limited data on HBD2 levels and its expression in the skin of patients with allergic skin diseases, further research is needed to elucidate the underlying causes and mechanisms of elevated HBD2 levels in these conditions.</p>","PeriodicalId":45914,"journal":{"name":"Acta Dermatovenerologica Alpina Pannonica et Adriatica","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142356086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
