This case study reports a 15-year-old female diagnosed with traumatic anserine folliculosis linked to prolonged friction on the chin, with improvement noted upon adjusting behaviors causing pressure.

This case report describes a 29-year-old man with a year-long non-itchy skin eruption and hair loss, with distinct papules and plaques across his scalp, beard, body, and suprapubic regions, but no systemic symptoms or family history of autoimmune disease.

This study reports that the asebia-2J mutation in mice affects sebaceous gland function and leads to hair follicle destruction, offering a model for human scarring alopecias.

This article offers a viewpoint on hidradenitis suppurativa pathogenesis, suggesting that impaired Notch signalling from γ-secretase mutations may drive inflammation and link the condition to other Th17-driven diseases.

This case report highlighted an instance of lichen spinulosus emerging as a new cutaneous sequela in a boy following toxic epidermal necrolysis, responding to treatment with ammonium lactate.

This study suggests that the "spade sign" is a highly specific histopathologic feature of acne keloidalis, although its absence does not rule out the condition.

This study identified a new variety of central centrifugal cicatricial alopecia that includes patchy hair loss on the lateral and posterior scalp in African-American women, which could be misdiagnosed as traction alopecia without dermatoscopy and pathology.

This study found that specific gene upregulations and mutations in hidradenitis suppurativa skin support the role of inflammation, altered epithelial differentiation, and metabolism dysregulation in the disease's pathogenesis.

This review discusses the role of dermoscopy in diagnosing hair and scalp disorders, noting its ability to aid in differential diagnosis without the need for biopsies; it reports no new clinical results.

In this case report, a novel missense mutation c.1360G>C (p.Ala454Pro) in the MBTPS2 gene was identified in a boy with typical IFAP syndrome and severe atopic features, although no phenotype/genotype correlation was established.

In this study conducted at a tertiary dermatological clinic, researchers identified and described the clinical, dermoscopic, and histopathological features of preclinical folliculitis keloidalis, including novel dermoscopic findings such as perifollicular scale, which was associated with fibrosis.

This review elaborates on follicular unit extraction as a hair restoration procedure and provides a detailed step-by-step guide but does not present new clinical results.

This review examines the clinicopathologic features of perifollicular elastolysis and indicates that, while its presentation is consistent, there is a lack of high-certainty evidence for effective treatments.

This review explains that dysregulated sebum secretion and composition contribute to acne and impaired skin barriers while highlighting factors like diet and hormones affecting sebaceous activity, and identifies novel molecular targets and model systems for future therapeutic developments.

This study observed that in a series of 28 patients with different types of alopecia, specific trichoscopic markers like exclamation-mark hairs and yellow dots helped distinguish alopecia areata from conditions like lichen planopilaris and discoid lupus erythematosus, which showed follicular ostia loss and white scarring.

This review explores low-level light therapy's potential as a noninvasive treatment for various forms of alopecia, noting its promising results in hair regrowth and density but highlighting the need for standardized protocols and further research.

This case report describes a 3-year-old boy with atrichia with papular lesions, emphasizing that dermoscopy, showing the 'cluster of stars' appearance, facilitated diagnosis without needing a skin biopsy.

In this study, NAC was observed to counteract the negative effects of cyclophosphamide on hair follicles in mice, preserving both biochemical parameters and hair structure, suggesting its potential as a therapeutic option for chemotherapy-induced hair loss.

This source highlights the challenges in treating cicatricial alopecia, noting that follicular unit extraction hair transplantation offers a minimally invasive and successful option to improve cosmetic outcomes for patients with permanent hair loss from scarring.

This study identified genetic variants in the DSG4 gene associated with the autosomal recessive form of monilethrix in Chinese patients, expanding the understanding of its phenotypic spectrum and clinical features.

This study found that applying controlled hypobaric stress to the skin significantly improved the in vitro and in vivo penetration of macromolecules, facilitating enhanced drug delivery.

This article describes adult female acne as a complex condition affected by genetic, hormonal, and environmental factors, with hormonal therapies highlighted as particularly valuable for treatment.

This study reports the case of an elderly patient with a keratosis pilaris-like skin eruption after beginning treatment with imatinib for chronic myeloid leukemia, discussing similar skin reactions to BCR-ABL inhibitors and exploring potential mechanisms behind these adverse cutaneous reactions.

In this case report, a 65-year-old woman with non-small cell lung cancer experienced scarring alopecia with papulo-pustular lesions on the scalp due to gefitinib treatment, marking it as a rare instance of gefitinib-induced erosive pustular dermatosis of the scalp.

This study suggests that polyamines regulate CK2 enzyme activity and its subcellular distribution, as demonstrated in mouse models and cell cultures with elevated levels of ornithine decarboxylase.

This study provides a framework for understanding different types of alopecias based on immune privilege collapse at specific follicular sites, revealing distinct patterns in immune effector programs and stromal influences depending on the alopecia type.

This review synthesizes current research on how the interaction between the skin microbiome and exosome-mediated communication influences hair disorders, and discusses how microbiome restoration and exosome-based therapies could advance treatments for conditions like alopecia by promoting hair regrowth and follicular health.

This review discusses evidence-based guidance for managing primary cicatricial alopecias but reports no new clinical results, highlighting significant gaps in knowledge and the need for more quality trials.

This article reviews various types of scarring alopecia, detailing their inflammatory characteristics, but presents no new clinical findings.

This study found that the vehicle of hydrocortisone impacts its absorption and therapeutic effectiveness, as demonstrated by efficacy tests using UV-erythema and vasoconstriction models.
