Small white dots on the scalp seen with a dermoscope correspond to sweat ducts and vary with different hair disorders.

This study reported that imaging characteristics of sebaceous nevus vary significantly by age group, revealing dynamic developmental changes that can be effectively identified through dermoscopy and reflectance confocal microscopy, offering noninvasive diagnostic potential.

This study describes GPRC5D's unique expression pattern in tissues that produce hard keratin, with retinoic acid inducing its expression in hair bulb cells and affecting keratin gene regulation.

This report discusses a case of reticular erythematous mucinosis syndrome, highlighting minimal mucin deposition and significant lymphocytic infiltration around the hair follicle, contributing to the ongoing debate about its nature as a mucinosis.

This study observed abnormal extracellular matrix patterns in hair follicles from alopecia areata patients, particularly in the dermal papilla of large anagen follicles and in catagen follicles from lesional sites.

Touch domes in human skin are complex sensory structures not directly linked to hair.

In this case report, a 16-year-old African American girl with sebaceous filaments on her face was successfully treated with topical tretinoin, highlighting the importance of recognizing and treating this under-reported condition for improved appearance and quality of life.

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 study observed that albino rats, despite not producing melanin, have melanocytes localized in specific skin areas of their hair matrix, suggesting that gene expression analysis of their skin should consider regional differences in melanocyte presence.

This study found that nevoid basal cell carcinomas originate in the epidermis and upper hair follicles, resembling early nonnevoid basal cell carcinoma proliferations.

This study found that hair germ and epidermal basal cells differ in keratin expressions in rat hair tissues, with hair-specific keratins appearing after the differentiation of each layer.

This study found that rete ridge morphogenesis in mammalian skin is directed by a BMP-dependent developmental program, which is evolutionarily distinct from other known pathways controlling the development of hair follicles, sweat glands, and fingerprint ridges.

This study suggests that typical skin lesions in Carney complex may originate from the pro-melanogenic activity of a specific dermal fibroblast population influenced by PKA signaling.

This case report discusses a 5-year-old Persian cat with feline eosinophilic granuloma complex, which responded positively to prednisone and topical corticosteroids, eliminating itching and promoting fur regrowth without relapse.

This case report describes a rare instance of sarcoidal granulomatous alopecia areata in a 42-year-old man, with histopathological findings suggesting inflammation but ruling out causes like tuberculosis and syphilis, resulting in treatment with tofacitinib.

This case report describes a strong dermoscopic and histopathological correlation in lichen nitidus, helping differentiate it from other similar conditions.

This case report details a 52-year-old man's successful hair regrowth following treatment with griseofulvin for Trichophyton tonsurans-induced scalp ringworm.

This study found that Gp₄G increased hair length, papilla cell numbers, and versican deposition in treated animals, potentially through alterations in hair follicle phases and nucleotide concentrations.

In this study, the authors concluded that arabinogalactan proteins recognized by specific antibodies are involved in the differentiation and development of barley root epidermal cells, contributing to root hair development.

This study reports an abnormal onion-shaped swelling on the hair shafts of some Abyssinian cats, affecting the appearance of their coat, though skin and hair structures appear normal under the microscope.

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 case report describes the histopathological features of nevus psiloliparus in an 11-year-old girl, noting "shadow" follicular units with loosely arranged collagen and reduced elastic fibers.

This study presented a case series of erosive pustular dermatosis on the scalps of elderly patients, noting unusual presentation with hypergranulation tissue and unique dermoscopic vascular patterns, diverging from typical manifestations.

This study suggests that the epidermis of monotremes and marsupials exhibits a more primitive pattern of protein distribution compared to eutherian mammals, with differences in loricrin distribution and keratinocyte maturation.

This study investigates calcium and phosphorus accumulations in the hair of mummies from the Taklamakan desert and debates their exogenous or endogenous origin.

This study found that GFRα2 influences cell size but not survival or target innervation of Ret-positive low-threshold mechanoreceptors in mouse dorsal root ganglia, differing from its role in nonpeptidergic nociceptors.

This study found that Rac1 activity in specific skin compartments is sufficient for hair formation, but results in hair with altered structure and pigmentation compared to normal.
