This study found that feeding mice high levels of dietary vitamin A increased WNT signaling, which activated hair follicle stem cells and may have accelerated alopecia areata progression.

This study reports a rare case of an 8-year-old boy with both alopecia areata and vitiligo coexisting within the same lesion on his scalp.

This study concluded that to accurately calculate the transection rate in follicular unit extraction, it's essential to account for both extracted and hidden transections, which differ based on surgeon expertise.

This abstract contains author information and a disclosure regarding the Mohebi Inserter for hair transplantation but provides no new clinical research findings.

This study observed that a dual-loaded niosomal in situ gel delivered effective antimicrobial and antioxidant properties for potential ophthalmic applications, showing superior inhibition of methicillin-resistant Staphylococcus aureus adhesion.

In this study, patients experienced scarless regenerative healing of scalp donor wounds, and the researchers highlighted that proper wound dressing can prevent alopecia and scarring in infected wounds, suggesting the potential of scalp skin grafts for optimal healing.

This study developed a multiscale spatial atlas of healthy skin and basal cell carcinoma, revealing a hair follicle origin for BCC and the expansion of specific cell populations such as POSTN+ fibroblasts and RGS5+ pericytes, suggesting roles in skin cancer stroma expansion and vascular remodeling.

This letter to the editor discusses excessive hair growth observed around local β-interferon injection sites for malignant melanoma but reports no new clinical results.

In this report, a case of a bullous lesion developed at the injection site in a patient treated with PEG-IFN-α-2a for chronic hepatitis C was described.

This article discusses the concept of "donor dominance" in androgenetic alopecia, where grafted hair continues to grow in bald areas, but reports no new clinical findings.

This case report describes a rare occurrence of nevus comedonicus on the scalp of a 19-year-old woman, highlighting its unusual location and classic appearance.

This retrospective study found that applying local skin precooling before scalp nerve block significantly reduced injection site pain during PRP mesotherapy for patients with androgenetic alopecia, compared to those who did not receive precooling, thus improving patient comfort and compliance.

This study developed a comprehensive atlas of human scalp tissue to uncover cell states and lineages in hair follicles, identifying disease-specific cellular changes associated with non-scarring and scarring hair loss, which may offer new diagnostic and therapeutic insights.

This case study reports the first known instance of basal cell carcinoma developing at the site of repeated microneedling for androgenetic alopecia, suggesting further research is needed to assess the long-term safety of such devices.

This case report describes the first instance of basal cell carcinoma developing at the site of repeated microneedling for androgenetic alopecia, highlighting the need for further safety studies.

In this study, a case of a 20-year-old woman revealed ectopic acanthosis nigricans at a post-syndactyly-release surgical site, suggesting this rare condition could result from epidermal–dermal mismatch and altered growth factor signaling in grafted skin, without indicating any metabolic or malignancy concerns.

This study analyzed animal hairs from 18th-century burial sites in Mazamet, France, reporting distinct hair morphologies consistent with the use of common local animal furs such as goat, badger, cow, or horse, reflecting the modest socioeconomic status of the individuals interred.

In this report, two cases of melanocytic matricoma, a rare benign hair follicle lesion that mimics melanoma and basal cell carcinoma, were described and successfully treated with complete surgical excision. Histological analysis was crucial for differentiation from similar malignant lesions.

This study using scRNA-seq on 96 skin biopsies from 51 healthy individuals revealed distinct cell signaling pathways in different skin sites, including unique pathways in facial and palmoplantar skin, which may explain their varying susceptibilities to skin disorders.

This report describes a woman with microcystic adnexal carcinoma who underwent successful excisional surgery and hair transplantation, which may be beneficial for treating surgical scars.

In this study, researchers used single-cell RNA sequencing to identify cell types and molecular differences in subcutaneous adipose tissue from various anatomical sites, suggesting that certain subpopulations of human adipose stem cells might improve the treatment of chronic refractory wounds.

Hair transplantation can improve scars after removing a rare skin cancer.

This study introduced a volar skin excisional wound model that closely mirrors human wound healing and supports evaluation of skin regeneration with multiple appendages and innervation.

This report presents a rare case of trichoadenoma occurring in the vulva, adding to the limited instances documented in medical literature.

This study found that younger age and preexisting acne on the scalp, face, and neck may increase the risk of developing folliculitis after hair restoration surgery, but the overall prognosis for hair growth is generally positive.

In this study, nanoemulsion formulations were found to significantly enhance the skin retention of the antiseptic agent triclosan, with the optimal mixture being a low surfactant concentration, as demonstrated through quantitative and qualitative analysis using tape-stripping and micro CT scans.

This article outlines the comprehensive content of the Dermatologic Surgery journal, which covers a wide range of topics related to cosmetic and reconstructive skin surgery, including skin cancer, but presents no new clinical results.

This article reflects on the various factors that influence results in hair restoration but presents no new findings.
