This paper reviews Satoyoshi syndrome and suggests diagnostic criteria to differentiate its subtypes, emphasizing the importance of testing alopecia areata patients for antinuclear antibodies, muscle spasms, and diarrhea.

This case report describes a 15-year-old girl with features of Becker naevus syndrome, highlighting the importance of DNA analysis from skin to confirm the diagnosis after 9 years of symptoms.

This study found a strong negative correlation between serum adiponectin levels and severity of hair loss in individuals with alopecia areata, suggesting adiponectin as a potential marker for disease severity.

This study examined skin biopsies from a woman with Addison disease and found melanocytic hyperpigmentation in the epidermis, with a notable melanocyte/keratinocyte ratio indicating increased melanocyte presence in the arm compared to the thigh.

This study found that sex steroid hormone receptors are largely maintained during the transformation of skin appendages to neoplasms, except for androgen and estrogen receptors in sweat and sebaceous gland tumors.

This case study diagnosed a cat with pituitary-dependent hyperadrenocorticism, confirmed by specific hormonal tests and post-mortem findings of adrenal hyperplasia and a pituitary adenoma.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

This study found that in a mouse model, alopecia areata was associated with changes in heart structure, biochemistry, and gene expression linked to cardiac hypertrophy after ACTH exposure.

This study found significantly higher P-Smad2 levels in both lesional and nonlesional skin of organ transplant recipients, suggesting elevated TGF-β signaling might contribute to their increased cancer susceptibility.

This case report details a 31-year-old woman with a subcutaneous nodule on her hand characterized by necrosis and lymphocytic infiltrate.

This case report details a 26-year-old woman with a rare large functional adrenal myelolipoma, characterized by elevated hormone levels and requiring surgical intervention.

This study suggests that exogenous retinoic acid can alter the morphogenesis pathway of developing skin appendages when applied during the placodal stage, leading to changes like feather formation in atypical regions of chick embryos.

This chapter reviews scalp and facial reconstruction techniques and includes updated illustrations, but it reports no new experimental findings.

This article reviews the similarities in early development processes of hair follicles, teeth, and mammary glands and reports no new experimental findings.

This case report highlights a 17-year-old female with Kartagener's syndrome and ectodermal anomalies, such as alopecia and dental issues, suggesting a possible novel syndromic variant, with genetic testing recommended to distinguish it from a dual diagnosis.

In this study, a deproteinized bone mineral showed potential to increase DHT production, suggesting an anabolic effect on human periosteal fibroblasts with possible implications for wound healing.

In this case study, a 15-year-old obese boy was diagnosed with acanthosis nigricans and hair casts in the axillae, with Wood's lamp and dermoscopic examination revealing specific features, yet fungal infection was ruled out through a negative KOH test.

This case report concludes that a combination of physical examination, hormonal evaluation, and imaging studies is crucial for identifying malignant adrenal masses, with radical excision and adjuvant therapy improving patient outcomes.

This case report details a 12-year-old boy from rural south India diagnosed with syringolymphoid hyperplasia, which presented with alopecia and anhidrosis.

This study investigated the immunohistochemical characteristics of keratin proteins in epidermal appendages, finding variable staining patterns in different skin structures and tumor cells, which suggests differences in keratinization.

This study found that dermal papillae in alopecia areata, including clinically normal follicles, exhibited ultrastructural abnormalities that suggest an early pathological role in the disease's development.

This systematic review of Mendelian randomization studies reports that autoimmune thyroid disease is associated with increased risk for numerous health conditions, including coronary atherosclerosis and rheumatoid arthritis, while decreasing risks for others, such as lung cancer.

This study describes how arrector pili muscles form a single muscular structure shared by all hair follicles within a follicular unit at the isthmus level in scalp skin.

This study found that laboratory testing practices for alopecia areata vary among international hair experts, with the majority routinely conducting thyroid function and complete blood count tests, yet exhibiting diverse approaches toward testing for other conditions or before prescribing systemic therapy.

This study revealed that during avian skin development, complex tissue architecture results from specific cellular flows and mechanical processes that guide feather bud protrusion and elongation, with distinct differences noted in scale development, where rigidity restricts such transformations.

This study found that incorporating dermal papillae cells and keratinocytes into dermal substitutes promoted better wound healing, reduced contraction, and enabled appendage formation in tissue-engineered skin on mice.

In this study, researchers engineered ventral skin organoids (vSkOs) with specific cellular compositions and signaling environments to generate human amnion-like tissues called Amnioids, offering new tools for studying human development and potential regenerative therapies.

This study found that skin adnexal tumors are mostly benign, with 98.6% of cases being non-cancerous, and highlighted histopathological examination as essential for accurate diagnosis and management, given their frequent clinical misdiagnosis.

This study reports that KRTAP-like proteins, which resemble keratin-associated proteins found in mammals, are also present in the cornified teeth of various lamprey species, suggesting these proteins may serve similar functions in skin appendages across different vertebrates despite independent evolutionary origins.

In this study, researchers analyzed alpaca skin morphology and found that type I and IV collagen are present in both the epidermis and dermis, while type III collagen is found only in the dermis.
