In this study, researchers used a hypospadiac rat model to demonstrate abnormal genital development, similar to human penoscrotal hypospadias, highlighting the model's value for studying penile growth and differentiation.

This study observed that in long-haired cat breeds, there is an inverse relationship between epidermis thickness and hair cover thickness, regardless of breed.

This review summarizes the clinical, dermoscopic, and histopathological features of keratoacanthoma and discusses treatment strategies, emphasizing dermoscopy's role in diagnosis and individualized treatment planning.

This article proposes a new classification system for cutaneous adnexal cysts based on their origin in the folliculo-sebaceous unit and sweat glands, aiming to clarify their categorization and origins.

In this study, researchers found that bulge cells cultured from rat hair follicles demonstrated stem cell characteristics and could differentiate into neural and glial lineages.

This study found that human hair follicles demonstrated a dose-dependent response to light in an ex vivo photoepilation model, which could predict the clinical efficacy and permanency of light-based hair removal devices.

In this study, the researchers reported that their novel algorithm for hair restoration in dermoscopy images achieved high accuracy and texture preservation, outperforming other techniques in diagnostic accuracy and texture quality measures.

This study provides further evidence for a genetic basis of PCOS, showing that polycystic ovarian morphology is a marker of inherited biochemical features in families with PCOS.

This case series reports three novel and atypical morphological patterns of alopecia areata, termed the central sparing, paw, and punctate patterns, highlighting their importance for dermatologists in improving diagnosis and management of the condition.

This study found that participation in a training workshop can significantly improve the reliability of evaluating ultrasonographic features of polycystic ovaries, suggesting standardized training modules should be used for consistent diagnosis of PCOS.

This study found a significant association between patients' sex of rearing and external genitalia in those with gonadal dysgenesis, while noting lower testosterone levels compared to controls.

The authors concluded that establishing and standardizing methods for data collection are crucial to improving PCOS diagnosis and research due to challenges observed in data harmonization across diverse international cohorts.

This review found that while follicular hair counts and ratios assist in diagnosing non-scarring alopecia, they should be used alongside specific morphological features for accurate diagnosis.

This study developed an automated image analysis framework for diagnosing hair disorders using trichoscopic images, reporting a Random Forest classifier as having an 86.67% accuracy in distinguishing between different scalp pathologies based on quantitative image features.

This study reviews polycystic ovary syndrome and vitamin D, reporting no new results, and notes the involvement of vitamin D receptors and insulin in ovarian function.

This study examined the morphological features of buffalo lips, finding that their structure includes distinct layers of skin, muscle, connective tissue, and glands.

This research explored the impact of chemotherapy on scalp conditions in cancer patients, finding significant textural differences through imaging analysis between those who experienced hair loss and those who retained hair, suggesting potential changes in scalp morphology during hair regrowth.

This article examines the morphological and physiological characteristics of eyelash follicles and offers clinical management suggestions for conditions like eyelash loss and trichomegaly, but presents no new clinical results.

This study analyzed trichoscopic features of discoid lupus erythematosus on the scalp in skin of color and found distinct patterns based on clinical morphology.

This study shows that multiphoton microscopy can non-invasively distinguish between scarring and non-scarring alopecia by identifying certain morphological features, but further research is needed to confirm its clinical utility.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This study shows that multiphoton microscopy can non-invasively distinguish scarring from non-scarring alopecia by identifying specific morphological features in hair follicle structures.

This case report describes a Thai male with TRPS1 who exhibited unique and unreported features such as hypoplastic mandibular condyles, double mental foramina, and distinctive hair abnormalities.

This study reported that the coat hairs of golden takin, living in harsh environments, have unique structural features compared to cattle, with overcoat hairs having continuous medullated tissue and undercoat hairs being finely crimped, potentially contributing to temperature regulation in cold conditions.

This study investigated the hair structure of wild pigs in the Balıkesir region using stereomicroscopy and scanning electron microscopy, finding distinct bifurcation patterns, but concluded that pig bristles used in brushes likely wouldn't retain these features, complicating species identification.

This study examined the morphological variations of terminal hair from different body regions of a Caucasian male, finding notable differences in diameter and features like "steak-boning" in specific hair types.

In this study, chemotherapy-induced alopecia in cancer patients showed specific trichoscopic patterns and abnormal hair shaft morphology, suggesting intermittent follicle damage from chemotherapy, but larger studies are needed for confirmation.

In this study, subclinical hypothyroidism in women with PCOS was linked to changes in the thyroid-prolactin axis and a lack of correlation between TSH and AMH, while gonadotropin levels and ovarian morphology remained unaffected, indicating the need for further prospective research.

This study found that the weak tensile strength of pili torti hair may result from loose keratin intermediate filaments due to abnormalities in disulfide bonds.

In this study, researchers examined the skin of neonatal rabbits and found that most hair follicles were in the terminal stage, with hair shafts protruding through the epidermis, but noted the absence of sweat glands.
