Abstract
Virtually all deaths in young patients with advanced skin tumors are caused by melanoma. Today, thanks to modern treatments, these patients survive longer or can even be cured. Advanced melanoma is often associated with a poor prognosis, and physicians continue to believe that the disease is difficult to treat due to the lack of durable response to initial treatment regimens and the lack of randomized clinical trials in the post-immunotherapy/targeted molecular therapy setting. New therapeutic targets are emerging based on preclinical data on the genetic profile of melanocytes and the identification of molecular factors involved in the pathogenesis of malignant transformations. In this article, we present the challenges of diagnosis, molecular biology and genetics of malignant melanoma, as well as current treatment options for patients with this diagnosis.

Abstract
Dysregulation of long non-coding RNA may lead to various diseases including cancer. Recently, many lincRNAs have been discovered for their important roles in melanoma, cutaneous squamous cell carcinoma (SCC), and basal cell carcinoma (BCC). These long non-coding RNAs are involved in skin cancer cell proliferation, angiogenesis, invasion, and metastasis.
Some long non-coding RNAs are upregulated in Non-melanoma Skin Cancer (NMSC), including PICSAR, PRECSIT, LINC01048, MALAT1, LINC00319, AK144841 in SCC and H19, CASC15, SPRY4-IT in BCC. In contrast, some long non-coding RNAs are down-regulated in SCC, including TINCR, SMRT-2, and LINC00520.
Many non-coding RNAs are specifically expressed in certain tissues or cells, and others are associated with tumor staging, drug resistance, and prognosis. Hence, non-coding RNAs can be used as diagnostic and prognostic tools in skin cancers.

Abstract
The limitations of common needles in drug delivery, such as pain, infection, and side effects, have become a stimulus to search for more efficient alternatives. Meanwhile, microneedles have brought new hope in skin drug delivery. These microstructures are temporarily placed in the upper layers of the skin and provide a painless and non-invasive way for drugs to pass through the skin barrier. Diversity in the design and ingredients of microneedles allows the release of a wide range of drugs with high efficiency and low side effects. On the other hand, nanomedicines are proposed as an ideal alternative due to the limitations of traditional drugs and the need for more targeted and less detrimental options. Nanomedicines are new drug delivery systems that are designed and produced in nanometer dimensions. These small particles can carry and release drugs directly to the target cells with high precision and efficiency. By reducing side effects and increasing the effectiveness of treatment, nanomedicines can play a key role in improving the quality of treatment for various diseases. Considering the unique advantages of the combination of microneedles and nanomedicines, it is an important issue to investigate different strategies for using these new systems in drug release. In this article, this issue has been investigated as well as the applications of nanomedicine transfer by microneedle in the treatment of diseases and the upcoming challenges of this emerging technology.

Abstract
Background and aim: Pityriasis lichenoides (PL) is a rare papulosquamous disorder with an unknown etiology. Due to limited recent studies on this subject, the present research was conducted to describe the clinical manifestations and treatment course of these patients.
Methods: This retrospective cross-sectional study (2019-2023) was conducted on patients diagnosed with PL at Razi Dermatology Hospital, Tehran University of Medical Sciences, Iran confirmed by biopsy of skin lesions. Basic information was obtained from hospital records, and treatment follow-up was gathered from medical files and phone interviews with patients. Data were analyzed using R software, with a P<0.05 considered statistically significant.
Results: A total of 147 patients were evaluated. No significant difference was found between genders (P=0.358). The predominant subtype was PLC (91.8%), with a mean age of onset of 29.79 ± 18.73 years. The most common type of skin lesion was papules (48.4%), and generalized body involvement was the most frequent manifestation, observed in 58 patients (32.4%). The most commonly used treatment was topical corticosteroids, administered to 86 patients (52.4%). The average duration from onset to full recovery was 160.80±221.40 days. A total of 45 patients (30.6%) reported recurrent episodes of the disease. No significant association was found between treatment efficacy and gender (P=0.620), underlying conditions (P=0.293), or age (P=0.876).
Conclusion: Given the limited clinical data on patients with pityriasis lichenoides, establishing an electronic database and a national registry system for this condition is recommended.

Abstract
Background and aim: Macular amyloidosis (MA) is a form of primary localized cutaneous amyloidosis (PLCA), characterized by amyloid deposits in the papillary dermis. This study aimed to compare the biophysical properties of MA lesions with those of adjacent uninvolved skin.
Methods: We measured several parameters in active MA lesions of 22 patients, including stratum corneum (SC) hydration, transepidermal water loss (TEWL), surface friction, pH, sebum, melanin, erythema, temperature, elasticity parameters (R0, R2, and R5), as well as epidermal and dermal thickness and echo-density using ultrasonography. Measurements from the lesions were compared with those from healthy skin adjacent to the lesions, serving as controls. Statistical analysis was performed using the paired t-test, with P-values less than 0.05 considered significant.
Results: Compared to adjacent normal skin, MA lesions demonstrated significantly lower SC hydration and surface friction, while TEWL, pH, erythema index, melanin content, and epidermal thickness were significantly increased. No significant differences were found in sebum levels, temperature, elasticity parameters, or dermal thickness and echo-density.
Conclusion: MA lesions exhibit distinct biophysical and ultrasonographic changes consistent with their histopathological features. These characteristic alterations may serve as useful, non-invasive markers for the early diagnosis of cutaneous macular amyloidosis.

Abstract
Kerion Celsi is a severe inflammatory fungal infection of the scalp that affects deeper layers of the skin. While it is uncommon in newborns, its incidence increases in children aged 3 years and older. It typically presents with swelling, spongy or boggy lesions, tenderness, hair loss (alopecia), and purulent discharge. Secondary bacterial infections are frequently seen following skin breakdown or maceration. Systemic symptoms may include enlarged lymph nodes, fever, and in very rare instances, fungal bloodstream infection (fungemia). Hypersensitivity reactions (Id reactions) can also occur. Diagnosis is guided by clinical evaluation, including patient history and physical examination, and must be confirmed using microscopy, fungal culture, and molecular diagnostic techniques. The most commonly isolated pathogens are anthropophilic Trichophyton tonsurans and zoophilic Microsporum canis. In contrast, geophilic fungi and molds are rarely implicated. Treatment is non-surgical, involving a combination of systemic and topical antifungal agents, with systemic antibiotics added when bacterial coinfection is suspected. Surgery should be avoided. Early and adequate therapy is critical to prevent permanent scarring and hair loss. The primary differential diagnosis includes bacterial infections of the skin and soft tissue.

Abstract
Skin infections caused by pathogenic bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa have become a serious challenge in the field of antibacterial therapies, especially in the context of antibiotic resistance. In this regard, the simultaneous use of classical antibiotic combinations with advanced nanostructures is considered a novel and effective approach. Narasin, an ionophore antibiotic of natural origin, has a high potential in inhibiting bacterial growth due to its ability to disrupt cell membrane function and ion transport. On the other hand, silica nanostructures, especially mesoporous silica nanoparticles, play an important role in enhancing antibacterial activity due to their properties such as biocompatibility, drug loading capability, controlled release, and production of reactive oxygen species.
Recent studies have shown that the combination of narasin with silica nanostructures enhances the synergistic antibacterial effects, increases drug stability, and improves penetration into bacterial biofilms. This combination has also been effective in reducing the dosage and systemic toxicity. Despite promising results in laboratory and animal models, challenges such as the assessment of cytotoxicity, precise release control, and the need for extensive clinical studies remain.
In this article, while comprehensively reviewing the properties and functions of narasin and silica nanostructures, the mechanisms of their combined effects on skin pathogenic bacteria are discussed and future prospects in the development of nanobiotechnological therapies are reviewed.

Abstract
Dermatophytes are keratinophilic fungi responsible for common and benign infections worldwide. However, in immunocompromised patients, they may lead to rare and severe diseases. Severe forms include widespread and/or invasive dermatophytosis, such as deep dermatophytosis and Majocchi’s granuloma. These cases have been reported in individuals with primary immunodeficiencies (such as autosomal recessive CARD9 deficiency) or acquired immunodeficiencies (such as solid organ transplantation, autoimmune diseases treated with immunosuppressive therapies, or HIV infection). The clinical manifestations of these infections are non-specific. Lymph node and organ involvement may also occur. Diagnosis requires mycological and histopathological evidence. There is no consensus on treatment. Systemic antifungal agents, such as terbinafine and azoles (e.g., itraconazole or posaconazole), are effective. However, the long-term outcome and management depend on the site and extent of the infection and the type of underlying immunodeficiency.

Abstract
Onychomycosis is one of the most common human fungal infections, affecting both fingernails and toenails and accounting for approximately 50% of all chronic nail disorders. It may be caused by various dermatophytes, yeasts (especially Candida spp.), and non-dermatophyte molds. Risk factors include advanced age, underlying conditions such as diabetes, immunosuppression, chronic moisture, and prolonged use of closed footwear. Accurate diagnosis requires clinical examination along with direct microscopy, culture, and, in advanced cases, molecular techniques. Treatment options include topical, systemic, or combined antifungal therapies, chosen based on the infection’s severity, causative agent, and patient status. Due to high recurrence rates, preventive measures and complete treatment follow-up are essential. This review provides a comprehensive overview of the epidemiology, clinical manifestations, etiologic agents, diagnostic methods, and therapeutic approaches to onychomycosis, highlighting current challenges in its management.

Abstract
Background and aim: Cutaneous melanoma is one of the most aggressive skin cancers with high metastatic potential and considerable mortality. Prognostic factors such as tumor thickness, surgical margin status, and lymph node involvement play a decisive role in prognosis and treatment selection. Reports from Iran also indicate an increasing incidence of this disease, and providing epidemiological and clinical data at the regional level can help guide therapeutic policies.
Methods: In this retrospective cross-sectional study, all patients with cutaneous melanoma who underwent surgery at Shahid Faghihi Hospital, Shiraz, between 2019 and 2023 were evaluated. Demographic information, lesion site, tumor size and thickness, histopathological type, surgical method, margin status, and the need for reoperation were extracted from medical records and analyzed using descriptive and analytical statistical tests.
Results: A total of 84 patients were included (51.2% male and 48.8% female). The most common histopathological type was malignant melanoma (31%). Lesions were most frequently located on the hands (28.6%) and feet (21.4%). The majority of lesions measured between 2–5 cm (36.9%). Only 2.4% of patients had tumors thinner than 1 mm, while 11.9% had tumors thicker than 5 mm. Excision was the most common surgical method (54.8%). Surgical margins were free of tumor in 53.6% of cases, and 61.9% of patients required reoperation.
Conclusion: The findings indicate that cutaneous melanoma in southern Iran predominantly occurs in the extremities, and the high rate of reoperation underscores the need for more precise surgical planning and earlier diagnosis.

Abstract
This article reviews the impact of isotretinoin on thyroid function, based on various clinical studies. Isotretinoin, a commonly prescribed treatment for severe acne, has been linked to significant changes in thyroid hormone levels, including elevated TSH and decreased FT3 and FT4. Several studies suggest that long-term isotretinoin use can induce thyroid dysfunction, with potential effects on thyroid volume, hormone levels, and the immune system. Autoimmune thyroid conditions, particularly autoimmune hypothyroidism, have also been observed in patients receiving isotretinoin. These findings highlight the need for regular thyroid monitoring during isotretinoin therapy, especially for patients with autoimmune predispositions. Additionally, the article emphasizes the importance of collaboration between endocrinologists and dermatologists to ensure optimal patient care. Further studies are needed to elucidate the mechanisms behind these changes and their clinical significance.

Abstract
This article reviews the impact of Menopausal Hormone Therapy (MHT) and oral contraceptives on melanoma risk. While some studies suggest an association between MHT and melanoma, conflicting evidence exists, including differences in drug formulations across countries, age at the start of treatment, and duration of use. Most studies have found no connection between oral contraceptive use and an increased melanoma risk, though environmental factors like sun exposure may play a role in this relationship. Overall, it appears that women should continue hormone therapy based on their healthcare provider’s advice, without specific concerns about melanoma risk.

Abstract
Background: Chronic granulomatous disease (CGD) is a rare primary immunodeficiency caused by defects in the NADPH oxidase complex, predisposing patients to severe bacterial and fungal infections. Dermatophytosis with severe inflammatory presentations such as tinea capitis is uncommon but challenging to manage in these patients.
Case presentation: We report a 9-year-old Iranian girl with autosomal recessive CGD who presented with refractory inflammatory scalp lesions. Mycological examination confirmed tinea capitis caused by Microsporum canis. Antifungal susceptibility testing showed reduced susceptibility to itraconazole, while susceptibility to terbinafine and fluconazole was preserved. Due to limited access to terbinafine, the patient received alternative management including antibacterial and anti-tuberculosis therapy, leading to clinical improvement.
Conclusion: This case highlights the diagnostic and therapeutic challenges of dermatophytosis in CGD patients and emphasizes the importance of accurate mycological diagnosis, antifungal susceptibility testing, and individualized multidisciplinary management, particularly in resource-limited settings.

Abstract
Over the past two decades, nanotechnology has played a pivotal role in transforming the cosmetic and personal care industry, establishing itself as one of the most revolutionary achievements in materials science. The reduction of particle size to the nanometer scale, by increasing the specific surface area and enhancing physicochemical properties, has enabled improved skin penetration, increased stability of active compounds, and facilitated the targeted release of active ingredients, leading to the production of products with higher efficacy. However, concurrent with the expansion of this technology, concerns regarding the biosafety, potential toxicity, and environmental consequences of nanoparticles have been raised, highlighting the necessity for rigorous evaluation. Therefore, this article aims to provide a comprehensive analysis of the advantages, limitations, and safety considerations associated with the application of nanotechnology in the cosmetic and personal care industry. In this analytical review, articles and sources published in reputable scientific databases between 2015 and 2025 were evaluated and analyzed. The results indicated that the utilization of nanostructures such as nanoliposomes, nanoemulsions, metallic nanoparticles, and lipid nanoparticles in the formulation of cosmetic products, while optimizing performance and increasing bioavailability, has created significant potential for innovation in this industry. Conversely, evidence has been reported regarding the induction of oxidative stress, inflammatory responses, and regulatory challenges in the context of long-term risk assessment. The application of nanotechnology in the cosmetic and personal care industry holds substantial innovative capacity and high added value; nevertheless, ensuring consumer safety necessitates long-term toxicological studies and the development of clear regulatory frameworks. Establishing a balance between industrial innovation and public health considerations is a fundamental condition for the sustainable development of this technology.

Abstract
Androgenetic alopecia (AGA) is the most common form of non-scarring hair loss in both men and women, characterized by progressive miniaturization of hair follicles in androgen-sensitive areas. This condition is usually genetically determined and influenced by androgenic hormones, particularly dihydrotestosterone (DHT). The present review aims to summarize the epidemiological, pathophysiological, clinical, and therapeutic aspects of AGA based on the most recent scientific evidence up to 2025. Current evidence indicates that AGA is not merely a cosmetic issue but also a significant factor affecting patients’ psychological and social well-being. Available treatments include FDA-approved medications such as finasteride and minoxidil, as well as emerging modalities such as platelet-rich plasma (PRP) injection, microneedling, and low-level laser therapy. However, limited efficacy, the need for long-term treatment, and the occurrence of adverse effects have prompted ongoing research into novel and combination therapeutic approaches.
