This study found that dermal papilla cells from human hair follicles form multi-layered aggregates when cultured in vitro, contrasting with the monolayer growth of dermal fibroblasts.

This study identified specific dermoscopic features for differentiating rosacea, seborrheic dermatitis, contact dermatitis, and atopic dermatitis, suggesting dermoscope's value in diagnosing facial erythema with atypical presentations.

This study reported significant upregulation and release of S100A4 in psoriatic skin, which may actively contribute to psoriasis pathogenesis.

This study suggests that trichoscopy may assist in diagnosing pemphigus, particularly for scalp-specific lesions, by identifying certain characteristic features.

This review discusses the clonal or polyclonal nature of skin carcinomas and the stem cell origins of basal and squamous cell carcinomas but presents no new research findings.

In this study, researchers found that the shape of polygonal domains, such as squares and triangles, significantly impacts Turing pattern formation, with domain geometry affecting the stability and type of bifurcations observed in simulations.

This report describes cases of trichoblastoma and trichoepithelioma in mixed-breed dogs, highlighting their distinct microscopic characteristics without suggesting broader clinical implications.

This study suggests that human hair follicle cells and epidermal keratinocytes differ in their degree of keratinization and other characteristics when cultured on mixed collagen membranes.

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 case report describes a child with hypopigmented mycosis fungoides successfully treated with UVA1 light therapy.

This study found that zinc treatment in alopecia areata patients may increase CD8+ cells, suggesting its effectiveness could be due to immunomodulation.

In this study, sweat duct differentiation was found to be a rare feature in trichilemmal cysts, occurring in only 0.97% of cases, and was likely under recognized.

This extensive review discusses the clinical manifestations, potential associations, and treatment approaches for lichen planus, but reports no new clinical results, highlighting gaps in evidence for therapeutic strategies.

In this case report, a rare instance of a primary cutaneous granular cell tumor with prominent overlying terminal hair growth in an adult is described, highlighting the importance of recognizing atypical presentations to accurately diagnose similar uncommon neoplasms.

This study demonstrated that cryogelation of human hair keratin allows the development of 3D scaffolds with tunable properties, supporting cell adhesion and proliferation for potential biomedical applications.

In this study, researchers found that neonate hairs have a distinct microstructure with no medulla and smaller hair follicles compared to adult hairs.

This study identified stem cells in the primary and secondary hair follicles and epidermis of Inner Mongolia cashmere goats, with BrdU labeling proving effective for up to 10 weeks.

An elderly man with skin amyloidosis and abnormal blood proteins was monitored without finding widespread disease after 18 months.

This study presents cases of paraproteinemic keratopathy associated with multiple myeloma and MGUS, highlighting varied treatment responses and the need for long-term follow-up to better understand disease progression and management.

This case report examines a patient with myasthenia gravis, invasive thymoma, and paraneoplastic pemphigus associated with alopecia areata, notably without the usual mucosal involvement.

This review discusses the diagnosis and management of acquired haemophilia and reports no new findings; the authors highlight the importance of early diagnosis to reduce mortality.

This case report suggests that intralesional cidofovir successfully treated SCC without systemic toxicity, making it a potential alternative to consider alongside surgical excision.

This study reviewed pathology reports of patients with multiple myeloma and found that skin biopsies commonly show graft-versus-host disease, drug-related lesions, and Sweet's syndrome, especially related to transplantation timing.

This study concluded that hair follicle hyperplasia found in pseudolymphomatous folliculitis can also occur in genuine cutaneous lymphomas, potentially as a coincidental result of underlying pathological processes.

This case report details a 77-year-old man initially suspected of having multiple myeloma but ultimately diagnosed with Waldenstrom’s Macroglobulinaemia, highlighting the importance of accurate differential diagnosis for conditions like epistaxis and high serum IgM.

This case study highlights the complexity of managing autoimmune polyglandular syndrome type 1, emphasizing the need for thorough clinical history, high suspicion for early diagnosis, and continuous long-term follow-up.

Skin lymphoproliferative disorders are hard to diagnose and often linked to systemic diseases, but most have a good prognosis with accurate diagnosis.

This case report details a rare instance of simultaneous onset of systemic lupus erythematosus and IgG4-related disease in a 73-year-old woman, where treatment improved symptoms by using high-dose glucocorticoids, hydroxychloroquine, and belimumab.

This study concluded that myositis in the reported case was caused by T-cell large granular lymphocytic leukemia, not dermatomyositis.
