This study observed that multinucleate giant cells were present in 31% of biopsy specimens from patients with male pattern alopecia but not in other alopecia types, suggesting a potential histologic marker for androgenetic alopecia.

This case study reports a female adult patient with annular elastolytic giant cell granuloma on the scalp, observed through dermoscopy showing multiple yellowish/orange follicular dots against an erythemato-whitish background.

This study found that human hair keratin scaffold material implanted in damaged rabbit muscle tissue degrades via the ubiquitin system and is further processed by macrophagocytes and lysosomes.

The authors diagnosed a 5-year-old Pekinese dog with keratoacanthoma with granulomatous inflammation, and the mass did not recur 5 months after surgical removal.

In this study, the degradation of HHK scaffold particles was linked to the activation and proliferation of satellite cells, which may contribute to new muscle fiber formation.

This case study suggests that treatment with Pil-Food, intended for hair loss prevention, may have triggered postinfantile giant cell hepatitis with autoimmune characteristics, which showed a rapid and effective response to corticosteroid therapy.

This study found that neural crest-derived hair follicle cells in mice can differentiate into osteoblast-like cells, suggesting a potential application for bone regenerative therapies.

This study found that epithelial components of calcifying epithelioma of Malherbe showed lectin binding and keratin staining patterns similar to normal hair follicles, with prominent Con A staining in tumor giant cells.

This review highlights the challenges in identifying histological features of adverse reactions to soft tissue fillers and emphasizes the need for increased awareness due to product uncertainty and delayed reactions.

This article reports on a typical case of lichen planopilaris with foreign-body granulomas around hair shaft material, suggesting these may be an additional criterion for diagnosing late-stage LPP/FFA.

This research found that hyaluronic acid increased cell proliferation and type I collagen more effectively than poly-L-lactic acid in both human fibroblast cultures and rat dermis.

This study analyzed pexidartinib-associated adverse events from FDA data and reported common events such as hepatic issues and systemic reactions. It highlighted sex-specific susceptibilities and reinforced the need for risk mitigation and long-term monitoring in tenosynovial giant cell tumor management.

This study analyzed skin biopsies from human monkeypox virus (hMPXV1) cases and found characteristic pustular stage features, including epidermal necrosis, shadow cell appearance, ballooned keratinocytes, and a dense inflammatory infiltrate, expanding histological knowledge crucial for understanding this disease and related Orthopoxvirus infections.

This case report describes a 32-year-old woman with a history of undifferentiated connective tissue disease who presented with cardiogenic shock, and endomyocardial biopsy revealed giant cell myocarditis, possibly indicating an association with her autoimmune condition.

This study found that eccrine duct dilation is significantly more frequent in cicatricial alopecias compared to noncicatricial alopecias, possibly due to the scarring process.

This study highlights the importance of recognizing oral lesions in diagnosing syphilis, as illustrated by three reported cases.

This study discusses incidental findings of syringomas and syringomatous proliferations in areas of scalp alopecia, suggesting they may be secondary to reactive changes from subclinical alopecia.

In this case report, researchers detailed a giant proliferating pilomatrixoma in a 36-year-old woman, emphasizing the importance of complete excision to prevent recurrence or potential malignant transformation, distinguishing it from malignancies like angiosarcoma or melanoma.

This review explores the role of TGF-β superfamily pathways in stem cell environments and their implications for tissue regeneration and cancer development, reporting no new experimental results.

This review highlights various methods of stem cell communication that reflect the unique organization and function of different tissues and reports no new results.

This review discusses circadian clock regulation in stem cells and its role in processes like neurogenesis, but reports no new results; the authors emphasize its significance in stem cell function across various tissues.

Minoxidil promotes hair growth by increasing cell division and DNA synthesis.

In this study, co-grafting human keratinocytes with murine dermal papilla-enriched cells produced hair follicle-like structures, but without regular hair formation, suggesting anomalous folliculogenesis.

This review discusses the role of immune cells in mammalian hair cycle control and highlights their potential relevance to human hair cycling disorders, reporting no new clinical findings.

Wnt/β-catenin signaling is crucial for cell fusion in placental development.

In this case study, a 51-year-old Japanese man was diagnosed with desmoplastic trichoepithelioma after histological examination of surgically excised facial plaques.

In this study, a 5-year-old Angus bull experienced systemic granulomatous disease and vasculitis potentially associated with grazing on hairy vetch, but other bulls in the same pasture showed no symptoms, suggesting variability in disease manifestation from similar exposures.

This chapter discusses the composition, biocompatibility, and production methods of biomaterials like collagen, chitin, and silk for dermal substitutes, focusing on preclinical and clinical research, but reports no new clinical results.

This review discusses the various roles of RANK signaling in bone remodeling, immune function, and epithelial differentiation, highlighting its potential involvement in cancer mechanisms; it reports no new clinical results.

The document explains various skin conditions and their treatments.
