This case report describes a twenty-year-old woman misdiagnosed with a sebaceous cyst that was actually pilomatrixoma, a benign skin lesion from hair matrix cells, confirmed by histopathology after excision.

A young woman with a rare fungal infection showed significant improvement after treatment with antifungal medication.

This study found that in superficial angiomyxomas, S100A4-positive mesenchymal niches may induce non-neoplastic adnexal epithelial growth, and highlighted evidence of mesenchymal-to-epithelial transition in eccrine duct branching, especially in Carney's complex cases.

This study observed that ECMs produced by papillary fibroblasts showed the largest fibers and supported keratinocyte differentiation better than reticular fibroblast matrices, informing biomimetic material design for skin tissue engineering.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This report describes a pancreatic mixed acinar-neuroendocrine carcinoma in a cat, underscoring its diagnostic complexity and the need to consider it in diagnoses of pancreatic masses with mixed features.

In this case report, an 18-year-old male's cheek lump initially diagnosed as a sebaceous cyst was found to be a pilomatrixoma after surgical excision and histopathological examination.

In this study, researchers found that β-catenin directly promotes TERT expression in stem and cancer cells by interacting with the Tert promoter, illustrating a mechanistic link between tumorigenesis and pluripotency.

This study identified the presence of recognizable organelles, such as lysosomes and mitochondria, in both the keratinized fiber and the hardened inner root sheath of the Romney wool follicle.

Cortexolone 17a-propionate may be an effective new treatment for hair loss.

A rare benign scalp tumor in an infant requires surgical removal.

This study found that lipid extraction increased water diffusion in wool and hair fibers; the effect was more pronounced in hair, indicating lipids are crucial for water permeability.

This study identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

In this case report, researchers described an exceptionally rare occurrence of a 19-year-old female having three concurrent pilonidal sinuses at intermammary, umbilical, and sacrococcygeal locations, with surgical and conservative treatment leading to favorable healing outcomes.

In this retrospective chart review, researchers found that keratinocyte carcinomas on the scalp and forehead of non-alopecic women occurred more frequently in the part line of the scalp, with basal cell carcinoma being more common than squamous cell carcinoma.

This paper reviews the complex histology of skin layers and underscores its importance for accurate and reproducible diagnosis in cutaneous pathology, but reports no new research findings.

This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.

This article describes cases of unusual scalp whorl patterns, including triple parietal and right temporal whorls, that were associated with normal development, and discusses theories of hair whorl development.

This study found that keratin immunohistochemistry suggests neoplastic cells in eccrine and apocrine poromas are closely related to dermal sweat duct cells, but cannot differentiate these poromas based solely on keratin patterns.

This study reports two cases of central serous chorioretinopathy developing after intralesional corticosteroid injections to the scalp for alopecia areata, suggesting a potential association that warrants cautious use and monitoring for ocular complications.

This study observed that pregnant women experienced an increase in hair cortisol concentrations, with primiparae having significantly higher levels in the last trimester compared to multiparae.

This case report describes the presence of a teratoma within an equine antral follicle and suggests that the ovary maintained functionality despite the teratoma, as indicated by active antral follicles and recent ovulation.

This report presents no new clinical results; it discusses the application of ACell MatriStem™, a porcine urinary bladder-derived extracellular matrix, in wound healing.

Systemic mastocytosis may cause a type of hair loss called cicatricial alopecia.

In this study, researchers identified CENPV as a new CYLD interacting partner that localizes to primary cilia and regulates acetylated tubulin levels, offering insights into the pathogenesis of skin appendage tumors.

This study concludes that SPARC is likely a secondary response during the hair cycle's transitional phases, indicating tissue-remodeling processes similar to those in wound repair, rather than initiating these transitions.
