This case report documents the first known occurrence of basal cell carcinoma at the site of repeated microneedling use for male androgenetic alopecia, underscoring the need for further studies on the long-term safety of such devices.

This review highlights that microtrauma, involving small intentional skin injuries, shows promise in stimulating hair growth in non-scarring alopecias by enhancing immune responses and increasing growth factor release, with methods like microneedling and PRP demonstrating efficacy.

This study found that micro-needling with cosmeceuticals or platelet-rich plasma significantly improved wrinkles, skin laxity, scar softening, and hair growth over 12 months, with minimal side effects, and that the best results occur with pigment and platelet massaging between 5 to 30 minutes post-treatment.

This study tested a microneedle patch on rabbit and pig models to support skin regeneration, revealing that the treatment accelerated wound closure, reduced scar formation, and promoted hair-bearing tissue and follicle growth, suggesting a trauma-guided framework for skin restoration.

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.

This case report introduces a novel instance of long-term cutaneous neoplastic degeneration following artificial hair implantation, a previously unreported complication in such procedures.

This study found that using minoxidil 2% as a mesotherapy injection showed more significant improvement in treating androgenetic alopecia in female patients than topical application.

This case study describes a 34-year-old male developing painful inflammatory scalp nodules post-scalp microinfusion of medication. The findings suggest that repeated microtrauma or bacterial colonization might trigger dissecting cellulitis in susceptible individuals, with exogenous testosterone as a potential modifier, not a direct cause.

This case study reported on a 6-year-old boy with frictional alopecia in the lower limbs, likely linked to his habit of cross-legged sitting and occasional rubbing, highlighting the condition's rarity in pediatric cases and emphasizing the need for further research in this age group.

In this study, 13 androgenetic alopecia patients receiving Er: Yag laser treatment showed a significant increase in Staphylococcus spp. three days post-treatment, suggesting the laser may help modulate scalp microbiota balance.

This study found that macrophages are crucial for skin regeneration during tissue expansion, as their depletion in rats led to inhibited skin growth and reduced secretion of key growth factors.

A man developed a rare blood vessel connection on his scalp after hair transplants, which was successfully treated with surgery.

This study found that intraovarian PRP treatment in women with low ovarian reserve was associated with significant increases in serum AMH levels in some patients, typically within four weeks.

This study found that Th17 lymphocytes may play a more crucial role than cytotoxic T cells in the development of alopecia areata due to their infiltration around the hair bulb/bulge, which exacerbates hair loss as histopathological grade worsens.

This study suggests that combining microneedling with ALA-photodynamic therapy may be a promising treatment option for moderate to severe alopecia areata, achieving significant hair regrowth in some patients.

This review discusses the use of microneedling for androgenetic alopecia and finds it promising for enhancing hair density and thickness, especially when combined with other treatments, but notes no standardized protocol exists yet.

This study found that in dogs with post-clipping alopecia, microneedling with platelet-rich plasma may induce more rapid hair regrowth compared to microneedling alone, though results were similar by six months.

This study examines the role of hair follicle stem cells in epidermal regeneration during skin soft tissue expansion, proposing a potential method for their cellular and molecular regulation.

This case report describes a 28-year-old male who developed a subpericranial abscess, an unusual complication of subpericranial hematoma, potentially related to microneedling procedures, highlighting a risk of infection even without open wounds.

This review discusses the roles of DNA methylation in skin development and regeneration, highlighting its impact on embryonic skin lineage, homeostasis, and potential therapeutic targets, but reports no new clinical results.

This article reviews the mechanisms and applications of photobiomodulation in trauma repair and medical aesthetics, but reports no new clinical results while highlighting its growing clinical significance.

This review discusses alopecia areata as a model for studying tissue-directed autoimmune diseases and reports no new clinical findings.

This review discusses skin changes during pregnancy, highlighting both pregnancy-specific and common physiologic changes, but reports no new clinical findings.

This study found that G protein-coupled estrogen receptor enhances melanin synthesis in melanoma cells through cAMP-PKA-MITF-TYR signaling, suggesting its potential as a drug target for chloasma treatment.

This review discusses the infection dermatophytosis in cats and reports no new results; it emphasizes the difficulty of eradicating the disease in shelters and catteries.

This study reports that plasma rich in growth factors appeared to improve hair follicle regeneration and patient satisfaction in individuals with androgenetic alopecia, though further trials are needed.

This study suggests that CD8+ cytotoxic T lymphocytes play a crucial role in the development of alopecia areata, based on observations in rodent models that mimic human autoimmune disease.

This review discusses feline dermatophytosis and emphasizes the importance of early detection and appropriate treatment, but it reports no new clinical results.

This review discusses the skin side effects associated with targeted cancer therapies and reports no new clinical results; it emphasizes the need for empirical management based on expert opinion.
