In this study, researchers observed that mechanosensory neurons initially develop similar morphologies across different skin regions but diverge post-natally, adapting to the type of skin they innervate, with bone morphogenetic protein signaling crucial for forming Meissner corpuscles in glabrous skin.

This review discusses the evolution of diagnostic criteria for polycystic ovary syndrome and emphasizes its association with various metabolic and cardiovascular risks, but it provides no new research findings.

This review discusses the current understanding of polycystic ovary syndrome, focusing on its epidemiology, pathophysiology, diagnosis, management, and future research directions, but reports no new clinical results.

This study suggests that a novel micropatterned dermal–epidermal matrix (μDERM) enhances keratinocyte function and epidermal morphology, offering potential improvements in skin substitute design for wound healing applications.

This case report describes a 26-year-old female with linear morphea and unique alopecia characterized by atrophic follicular remnants, resembling telogen follicles but indicating permanent alopecia, unlike typical findings in morphea-related alopecia.

This article reviews adverse skin reactions caused by chemotherapy and cytokine treatments, describing specific and nonspecific reactions, but reports no new clinical findings.

This study observed that inflammatory AIGA is associated with sweat duct inflammation and sweat coil atrophy, while non-inflammatory AIGA involves only sweat coil atrophy, suggesting distinct pathological features between the two.

This study found that Malassezia folliculitis, common among young adult males, can be distinguished from truncal acne by its clinical features and responds well to antifungal treatment.

This study found that training in a hypoxic chamber did not significantly impact skin features in overweight and obese women, though it did result in a notable reduction in body weight and BMI.

This case report details a 73-year-old woman with systemic sarcoidosis, whose scalp biopsy revealed features consistent with both sarcoidosis and frontal fibrosing alopecia, emphasizing the necessity of biopsy in complex alopecia diagnoses.

In this study, researchers found that dermoscopy revealed specific features in Malassezia folliculitis, such as folliculocentricity and perilesional erythema, which can aid in its identification and potentially distinguish it from acne vulgaris.

In this study, researchers characterized the clinical features of ophiasis, an uncommon type of alopecia areata, and proposed a new subtype classification that may help predict treatment response and guide management, noting that ophiasis generally has a chronic and refractory nature.

This systematic review and meta-analysis found that male first-degree relatives of women with PCOS have increased rates of metabolic issues, hormonal imbalances, and androgenic features compared to controls, suggesting a male equivalent of PCOS.

This study describes the use of a genetically engineered mouse model, mTurquoise2-Col4a1, to fluorescently label collagen IV and observe basement membrane dynamics during skin development, revealing its stability and pliability during rapid growth phases.

This study found that polycystic ovary syndrome was the most common cause of hirsutism among premenopausal Algerian women.

This study found that specific DNA variants in the TCHH, WNT10A, and FRAS1 genes are associated with predicting straight hair in Europeans, showing high sensitivity but low specificity, especially using a neural networks approach.

This report describes two unusual cases of lichen planopilaris in Caucasian patients, detailing features suggestive of folliculotropic mycosis fungoides and an overlap with systemic lupus erythematosus.

The researchers concluded that hairless dogs can serve as an effective model for studying hypertrophic scarring due to their development of scars with morphological similarities to human hypertrophic scars.

This review discusses the epidemiology, risk factors, clinical features, and management of scalp melanomas, highlighting their high mortality rates and specific challenges in diagnosis and treatment; it reports no new research findings.

This review discusses the basic principles of hair pathology and findings in common types of alopecia but reports no new research results.

Acute leukemias with the Philadelphia chromosome may be biphenotypic, and identifying this is important for proper treatment.

This review discusses the function and pathology of hair follicles and highlights the potential of using dogs as a model to study human hair and stem cell disorders, but presents no new experimental results.

This study found that the differential expression of α- and β-keratin genes in feathers may explain their morphological and structural diversity, highlighting the chicken as a model for studying keratin-related diseases.

This study found that telocytes in human scalp tissue were located around hair follicles and glands and may be involved in skin regeneration and homeostasis.

This study concluded that human epidermal stem cells cultured in MEM-α and EpiLife media with growth factors show high proliferation potential and plasticity, suggesting potential use in skin regenerative medicine.

In this study, the proposed MSF-VMDNet, combining dual encoder networks with a multi-frequency domain mechanism, significantly outperformed existing methods in segmenting skin cancer tissues from histological slide images, achieving high accuracy with an MIoU of 95.37% and a Dice coefficient of 95.11%.

This study found that mouse astrocytes formed cell spheres on agarose surfaces, acquired stem cell-like features, and their derived stem cells effectively differentiated into neurons that helped regenerate damaged nerves.

This review discusses the complex etiology of polycystic ovary syndrome (PCOS), highlighting its association with insulin resistance and hyperandrogenism, but reports no clinical findings; the authors suggest further investigation of the pathophysiological mechanisms.

This article provides an overview of how dermoscopy can aid in the noninvasive diagnosis of various general dermatological disorders, grouped by clinical presentation, but reports no new clinical results.

This article proposes a hypothesis that hyperandrogenemia is the final common pathway for developing adolescent PCOS and emphasizes the importance of reducing androgen levels to mitigate risks of metabolic syndrome, diabetes, and infertility in adulthood.
