This article reviews the clinical and histological features of acanthosis nigricans and its associations with insulin resistance and other conditions, but highlights the need for more research on its classification, severity assessment, and treatment options.

This article describes two cases of plica neuropathica, a rare hair condition involving severe matting, and discusses possible contributing factors and diagnosis methods while reporting no new scientific results.

This review discusses the development of Matrigel and its role in identifying thymosin beta 4 as a regenerative protein, without reporting new experimental findings.

In this paper, regression of proliferative necrotizing otitis externa lesions in young cats was reported following systemic and topical immunomodulatory therapy.

This study found that VEGF-deficient keratinocytes can form tumors using different aneuploidy and signaling patterns, highlighting VEGF's role beyond angiogenesis in tumor cell growth and survival.

This case report details an instance of Wolf's isotopic response, where a 76-year-old patient developed keloids at the site of a previous herpes zoster infection, highlighting the unclear pathogenesis and theoretical explanations for such occurrences.

This study found that overexpression of PKCɛ in mouse epidermis increased sensitivity to metastatic squamous cell carcinoma, suggesting that a PKCɛ-mediated microenvironment may promote cancer development through specific cytokines like TNFα.

This case study reports that selenium shampoo, bacterial infection with trichomycosis axillaris, and possibly strongyloides larvae may have contributed to acquired hair shaft abnormalities resembling trichorrhexis nodosa in two patients.

This narrative review and case report identified a rare association between erythema nodosum and kerion caused by *Trichophyton mentagrophytes*, with successful treatment using antifungals and corticosteroids.

In this case report, a 25-year-old man with nevus comedonicus showed no improvement from keratolytics and topical tretinoin, but had success with surgical excision of the lesions.

This article presents a case of trichostasis spinulosa, a common but often unrecognized disorder, diagnosed through dermoscopic examination of black macules revealing bundled vellus hairs, with the patient declining treatment.

This study proposed a hypothesis for cutaneous calcinosis, suggesting that feeding DHT and subsequent epilation lead to ATP release and calcium orthophosphate formation, initiating calcification in rats.

This study confirms previous observations that benign lipogenic lesions may contain eccrine/apocrine glandular components, potentially due to adipocytic proliferation entrapping glandular structures.

In this study, researchers examined the under-studied mechanisms behind specific dermatological phenomena such as co-localization, Wolf's isotopic phenomenon, Koebner's isomorphic phenomenon, and the recently described Renbök phenomenon, noting that only a few cases have been reported so far.

This case report identifies necrolytic migratory erythema associated with a glucagonoma in a 40-year-old man, presenting with distinct skin lesions, weight loss, and diarrhea.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This study reports that miR-22 promotes cancer progression and metastasis by maintaining Wnt/β-catenin signaling and cancer stem cell function.

This review explores the role of Foxn1 in mammalian skin biology, discussing its influence on hair follicle function and the potential for further research to enhance understanding of epithelial differentiation.

This study introduced fibronectin nanogel microneedles (FNG MNs) that demonstrated improved tissue penetration and transdermal delivery, restoring skin homeostasis in a photoaged mouse model and enhancing collagen deposition and angiogenesis in a diabetic wound rat model.

A rare skin growth was successfully removed without recurrence after one year.

This report describes an 11-year-old boy with Netherton syndrome who developed Cushing syndrome after using low-potency hydrocortisone ointment extensively, highlighting caution with long-term topical treatments in such conditions.

This review discusses the potential of natural products to induce ferroptosis as a promising therapeutic strategy for non-small cell lung cancer and reports no clinical results; the authors highlight the need for further comprehensive studies.

This study found that NLRP1 in human melanoma cells promotes tumor growth by enhancing inflammasome activation and suppressing caspase-3 activity.

This study found that using an electrical microneedling device enhanced the penetration of liposomal melanin-fluorescein into hair structures and widened the follicular infundibulum in ex vivo human skin models.

This study identified a new role for IL-4Ra-induced oxidative metabolism in wound macrophages, essential for balancing inflammatory response and promoting pro-fibrotic repair, suggesting a target for fibrosis prevention.

In this report, two cases of melanocytic matricoma, a rare benign hair follicle lesion that mimics melanoma and basal cell carcinoma, were described and successfully treated with complete surgical excision. Histological analysis was crucial for differentiation from similar malignant lesions.

This case report presents the first successful treatment of acne keloidalis nuchae with a combination of halobetasol 0.01% and tazarotene 0.045% lotion.

TGF-β signaling is essential for hair follicle regeneration during wound healing.

In this case report, researchers described a unique skin lesion in a 55-year-old woman, identifying it as folliculosebaceous cystic hamartoma with an unusual combination of spindle cell lipomatous and neural components, which had not been previously documented in such cases.
