This chapter discusses various skin functions and structures involved in protection, immune response, and homeostasis, but it reports no new research findings.

This review explores the complex interactions between hair follicle stem cells and surrounding structures that are essential for understanding hair regeneration, reporting no new experimental results.

In this study, testosterone-induced alopecia in male rats led to significant thinning and follicular degeneration, but treatment with adipose-derived stromal vascular fraction cells markedly improved these histological changes, suggesting a potential role in hair follicle regeneration.

This study reviewed cases of ocular adverse events linked to minoxidil use, finding central serous chorioretinopathy as the most common issue, with symptoms improving after discontinuation in many cases, yet causality remains uncertain.

In this study, naked mole-rats demonstrated unique skin and hair follicle innervation features compared to other species, suggesting adaptations to their subterranean environment and poikilothermy.

This article discusses the advantages and different techniques of dermoscopy for skin lesion visualization and reviewing no new clinical results; it emphasizes the integration of polarized light and the importance of training.

Shiny white structures in trichoscopy can indicate long-standing discoid lupus erythematosus alopecia.

This study at Shandong Provincial Hospital evaluated interventional embolization for scalp arteriovenous fistulas, finding a cure rate of 85.71% among 21 patients, with swelling as a common postoperative complication, suggesting this method is both effective and safe.

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.

This article reviews the current literature on rosacea, focusing on the new subtype classification system and the main theories of its pathogenesis, but reports no new clinical results.

This study found that improved outcomes in scalp surgery were achieved by utilizing knowledge of the surgical anatomy of the scalp to avoid complications like unsightly scars and distorted hair patterns.

In this study, the researchers found that transplanted hair follicles undergo significant morphological changes, including a thickened dermal sheath and increased hair shaft diameter, which are associated with altered follicular vascularization.

This report describes a rare case of angiokeratomas on both the upper eyelids and scrotum, adding to the limited literature on eyelid occurrences and discussing potential causes.

This hypothesis paper suggests that sexual and cognitive dysfunctions reported by some men after using finasteride and dutasteride may stem from vascular and tissue changes in penile tissue triggering broader inflammatory effects.

This review derived guidelines for scalp surgery suggesting improved outcomes when avoiding neurovascular structures, preserving tissue integrity, and maintaining hair direction, but it reports no new clinical results.

This study observed that multiphoton excitation microscopy revealed changes in vascular structure and hair papillae in mice subcutaneous tissue following cyclophosphamide treatment for chemotherapy-induced alopecia.

In animal models, this study reported that a wound dressing combining quaternized chitin and silk fibroin significantly enhanced vascular reconstruction and hair follicle regeneration, approaching normal tissue levels.

This review discusses advancements in artificial skin for wound treatment and reports no new clinical findings; the authors highlight the potential of new biomaterials to enhance future skin replacement therapies.

This review discusses the development of electrospun nanofibrous scaffolds for promoting angiogenesis in tissue engineering but notes that their clinical application beyond bone and skin repair is still limited.

This study suggests that trichoscopy may assist in diagnosing pemphigus, particularly for scalp-specific lesions, by identifying certain characteristic features.

In this study, researchers developed a near-infrared-responsive nanoplatform that synergistically enhances chronic wound healing by accelerating mitochondrial restoration and immune modulation, leading to enhanced wound repair and high-quality healing in diabetic rat models.

This study found that human outer root sheath cells express VEGF receptor-2, and exogenous VEGF165 significantly stimulates their proliferation through activation of the ERK signaling pathway.

In this retrospective study, researchers described the dermoscopic features of dermatitis cruris pustulosa et atrophicans in 30 patients, finding that follicular-based pustules and other specific features were predominant, with male patients being more affected and primarily involving the lower extremities.

This study found that cepharanthine and its structural analogues may stimulate hair growth by promoting the proliferation of human dermal papilla cells and increasing VEGF expression in vitro.

This study found that micro-CT imaging can effectively identify vascular structures in rat models of congenital hypospadias, providing anatomical insights for selecting preputial vessel flaps in surgical procedures.

This study demonstrated that CD19-CAR T cell therapy may promote structural regeneration in the skin of systemic sclerosis patients, as evidenced by histological improvements and fibroblast population changes, suggesting its potential for tissue remodeling in fibrotic diseases.

In this study, D-OCT imaging revealed distinct structural and vascular changes in patients with frontal fibrosing alopecia, highlighting the technique's potential for diagnosing and monitoring the condition's activity.

This study found that polycaprolactone (PCL) in facial fillers led to more cell proliferation and vascular activity than hyaluronic acid (HA) in Wistar rats, suggesting enhanced tissue regeneration effects with PCL.

This review highlights recent advancements in the engineering of skin organoids using hydrogels, which improve their structural and functional fidelity by supporting the architecture and integration of vascular and neural components, promising to enhance regenerative medicine, drug discovery, and complex skin disorder studies.

This review highlights that two-photon excitation microscopy is a valuable tool for visualizing live skin structures and immune responses at high resolution, though its clinical use is hindered by safety and cost issues.
