This article discusses the causes, development, treatment, and prevention strategies for pseudofolliculitis barbae and folliculitis keloidalis nuchae, but reports no new clinical results.

Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.

This case report describes a patient with Clouston syndrome who developed squamous cell carcinoma, highlighting the need for regular follow-up in patients with chronic paronychia that do not respond to conventional treatments.

Acquired perforating dermatosis often affects skin in people with kidney issues and diabetes.

This article reports that cocaine injections can lead to skin lesions containing talc crystals at the sites of injection.

This study observed that methylene blue staining and zinc iodide-osmium tetroxide techniques effectively revealed anatomical details of intraepidermal nerve fibre endings in the rat's mystacial pad, suggesting their potential role in mechanoreception.

This study found that activation of delta-opioid receptors in keratinocytes may delay the expression of the PER2 gene, suggesting a possible link to cancer development through circadian rhythm disruption.

This study found that enlarged facial pores in women show distinct microstructural alterations, including regular keratinocyte arrangement and irregular dermo-epidermal junctions, highlighting changes in skin tension linked to pore enlargement.

This study found that the Wnt-β-catenin pathway directly promotes TERT expression in both stem and cancer cells, highlighting a mechanistic link between tumorigenesis and pluripotency.

This study found that K6a expression in mouse sebaceous gland ducts correlates with Hedgehog signaling, suggesting a role in duct fate.

The document's conclusion cannot be determined from the provided text.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This case report describes two instances of habit tic nail deformities associated with alopecia areata.

This case study described the diagnosis of a trichofolliculoma in a 56-year-old woman, emphasizing its dermoscopic features and histological aspects that confirmed the tumor type, with no recurrence observed after excision.

A girl inherited excessive body hair from her mother and grandmother.

Chronic telogen effluvium is a condition where there is prolonged shedding of hair.

This case report describes the occurrence of a very rare disease, MTPC, in the elbow of a man who does not match the typical etiology, highlighting its academic significance.

This study found that ectopic expression of the lymphoid-enhancer factor can induce K17 protein in the skin, suggesting a link between skin development and wound repair processes in mice.

This review discusses three newly identified forms of epidermolysis bullosa related to mutations in DST-e, EXPH5, and ITGA3, offering insights into their genetic and clinical characteristics but reports no new clinical results.

This study found that CB1 receptor activation reduced keratin K6 and K16 expression in human keratinocytes in vitro and in situ, suggesting potential relevance for both psoriasis management and wound healing.

This study found that asynchronous differentiation in human anagen hair follicles involves specific localization of c-Myc and interrelated genes Max and Bin1 along the inner root sheath.

This case report describes a 33-year-old woman whose unilateral occipital pain and localized alopecia were only responsive to onabotulinumtoxin A, suggesting it might be a form of cephalalgia alopecia or nummular headache.

This case study describes a unique instance of warty dyskeratoma involving two adjacent hair follicles within one lesion.

In this case report, a 25-year-old man with nevus comedonicus showed no improvement from keratolytics and topical tretinoin, but had success with surgical excision of the lesions.

In this case report, a 38-year-old woman with Parry–Romberg syndrome displayed left-sided facial atrophy and subclinical central nervous system involvement detectable by neuroimaging, suggesting that even symptom-free cases may benefit from systematic brain evaluations.

In this study, transgenic mice expressing a mutant K6 gene developed progressive scarring alopecia and keratosis, suggesting they may model a new keratin disorder.
