In this study, researchers observed that in mice, as they age beyond 200 days, unusual curved hair follicles and increased white hairs emerge, indicating stem cell-related changes in keratinocyte and melanocyte characteristics, providing insights into hair aging processes.

This case report describes a 7-year-old boy with pityriasis versicolor presenting as scalp hypopigmentation, a rare distribution for this fungal infection. Diagnosis was confirmed via Wood's lamp examination and microscopy, and the condition resolved after treatment with topical terbinafine hydrochloride cream.

This review discusses changes in hair follicle characteristics and stem cell dynamics as indicators of aging in mice, noting increased occurrences of white hairs and curved hair follicles at older ages.

This study reports that aging in mice leads to curved hair follicles and an increase in white hairs, potentially due to changes in keratinocyte and melanocyte stem cells.

This case report describes a unique instance of an otherwise healthy infant with phylloid terminal hair nevus, a form of hypomelanosis without extracutaneous abnormalities.

This report discusses two cases of sarcoidosis with cutaneous manifestations that posed a diagnostic challenge, without presenting new clinical results.

This case study presents a 9-month-old male infant with symptoms suggesting a likely diagnosis of Hay–Wells syndrome, including severe scalp crusting, nail abnormalities, and partial syndactyly.

In this study, γ-ray exposure in mice decreased hair follicle density and pigmentation, suggesting damage to stem cells affecting hair follicle regeneration.

In this study, γ-ray irradiation in mice during the first telogen phase led to decreased hair follicle density and pigmentation anomalies, suggesting damage to stem cells and progenitors for keratinocytes and melanocytes.

This review discusses the increasing reports of rare cutaneous side effects from topical imiquimod, aiming to inform physicians and dermatologists about its potential adverse effects as its use expands.

This study observed distinct dermoscopic features in pityriasis versicolor that could aid in its differentiation from similar skin disorders.

A pregnant woman's skin condition improved after giving birth, possibly due to high estrogen levels during pregnancy.

Atopic dermatitis may have genetic causes and can be treated with pharmacologic methods, glycerin creams, and controlling Staphylococcus aureus colonization.

This review outlines various techniques to improve facial scars following trauma but reports no new clinical results, highlighting the need for further research to address psychosocial impacts.

This report summarizes recent cases of the rare condition erythromelanosis follicularis faciei et colli to illustrate its varied clinical presentations.

This study observed that the majority of side effects from laser-assisted hair removal were associated with ruby and alexandrite lasers, particularly in patients with tanned or darker skin types.

This study found that topical niacinamide significantly improved the appearance of wrinkles, skin yellowing, and elasticity in aging facial skin over 12 weeks.

This review covers the history, incidence, and treatment options for pseudofolliculitis barbae and presents new data, but reports no new clinical results.

This study found that high-dose-rate electronic brachytherapy was effective for treating nonmelanoma skin cancer, with no recurrences and good to excellent cosmetic results at 1 year or more.

This review discusses the structural differences between black and white skin, noting that black skin has more compact stratum corneum, larger melanosomes, and increased transepidermal water loss.

This study identified distinct clinical and dermatoscopic features to differentiate non-scarring patchy alopecia in SLE from alopecia areata, emphasizing the value of serological tests in diagnosis.

This article discusses using body and beard hair for hair restoration and reviews the indications, techniques, and risks involved, but reports no new clinical results.

This study found that normal-mode ruby laser treatment significantly improved facial hirsutism and maintained results for at least 48 weeks, with repeated treatments enhancing clinical effects.

This review discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

This case report observed that a selenium-deficient diet in a child with propionic acidaemia led to macrocytosis and hair abnormalities, which improved with selenium supplementation.

This case study documented a black male newborn developing large bullae that healed with hypopigmentation, suspecting proteolytic enzymes in keratinocytes caused the collagenolysis responsible for the condition.

This study found that using an argon gas-based system for intralesional cryotherapy significantly reduced keloid scar volume, improved scar quality, and resulted in low recurrence rates after 12 months.

In this study, vitiligo and alopecia areata were more common among patients with chronic graft-vs-host disease than previously reported, linked to higher NIH skin scores and greater immunosuppressive treatment.

This case report describes oleoma on the thighs and buttocks appearing two years after an injection for cellulite treatment, suggesting the need for more research to ensure the procedure's safety and efficacy.

This study found evidence that polythelia pilosa, previously excluded from classification, should be reintroduced as it marks true aberrant mammary structures in men and hirsute women.
