This case report describes a 27-year-old woman with lupus erythematosus whose biopsy findings indicated that lupus panniculitis can mimic alopecia areata, leading to temporary hair loss.

This case report describes the trichoscopic and histological features observed in a 7-year-old boy with morphea en coup de sabre and details the positive response to systemic immunosuppressive therapy.

In this animal study, researchers found that exposure to a CO2 laser at various power levels caused significant skin damage in rats, including severe burns, coagulation, and tissue obliteration, with higher laser doses resulting in more pronounced injuries.

This study observed that seborrheic keratosis lesions in five patients exhibited specific histological changes after trauma, suggesting a connection between these lesions and hair follicle structures.

Testicular microlithiasis may increase the risk of testicular cancer and patients with it should be closely monitored.

This study purified trichohyalin protein from pig tongue epithelium, characterizing its unique properties and structure, which may facilitate future functional research.

This study found that trichohyalin, a protein previously thought to be restricted to hair and tongue, is also present in isolated cells within the granular layer and stratum corneum of normal human epidermis.

This study found that trichohyalin is expressed in various normal and pathological epithelia beyond hair follicle cells, where it is uniquely associated with filaggrin, suggesting a specific role in aggregating K6/K16-containing intermediate filaments.

This study reports that a 190,000 molecular weight protein, identified as trichohyalin, may play a matrix role in the development of inner root sheaths in hair follicles.

This article discusses alopecia and the impact of hair loss on mental health, but it presents no new research findings and highlights the need for further studies.

This study suggests that intermediate-size hyaluronate fragments may enhance keratinocyte proliferation and improve skin thickness in atrophic conditions through a CD44-dependent mechanism.

This study suggests that trichohyalin is modified by peptidyl-arginine deiminase before being cross-linked by TGase 3, allowing the formation of rigid structures in hair follicle cells.

In this study, hyaluronic acid filler injections in albino rats increased subcutaneous tissue thickness, collagen and elastic fibers, and vascularization, suggesting potential benefits for combating skin aging and defects.

This article is a letter discussing a case of cutaneous lymphoid hyperplasia following hyaluronic acid filler injection and fat grafting, reporting no new results.

This review discusses the roles of filaggrin and trichohyalin in keratinocyte differentiation and reports no new results; the authors introduce possible hybrid granules in tongue epithelia.

This study found that hyaluronic acid increased the size and cell proliferation of mixed aggregates in a 3D culture model, indicating its role in human hair follicle germ-like structure formation without enhancing dermal papilla cell markers.

This study suggests that Rushton’s hyaline bodies form through both epithelial changes leading to hair keratin production and hemorrhage supplying erythrocytic substances, resolving previous debates about their origin.

This study suggests that hairless dogs' skin shows sensitivity to topical corticosteroids, highlighting their potential as a model for studying the efficacy and adverse effects of these treatments on skin.

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 article reviews treatment approaches for cicatricial alopecia, describing how medication efficacy varies and suggesting autologous hair transplantation for stable cases; no new clinical data are presented.

This review suggests that the inner root sheath of human hair follicles may have broader regulatory roles beyond structural support, potentially impacting processes like folliculogenesis, anagen phase regulation, and immunomodulation.

In this study, researchers observed that hidradenitis suppurativa lesions were associated with reduced collagen and elastin, and increased neovascularization in areas with chronic inflammation.

This article reports a case of a 30-year-old woman developing alopecia after a hyaluronic acid injection, with trichoscopic findings described for the first time.

This study found that human trichohyalin has a unique protein sequence potentially contributing to at least three important functions in hair follicle and epidermal cells.

This study documents that trichohyalin acts as a multi-functional cross-bridging protein in the inner root sheath of mouse hair follicles, enhancing mechanical strength by linking keratin filaments to the cell envelope.

In this study, the combination of biologically engineered hyaluronic acid and polyquaternium-10 improved hyaluronic acid's retention and moisturizing effects on hair by forming a stable complex that increased binding affinity to keratin.

This source reviews the use of hyaluronic acid fillers for lip augmentation and correction, highlighting their safety and effectiveness, while noting potential adverse effects and the importance of managing complications.
