This study reported that trichoscopy revealed distinctive patterns across different autoimmune bullous diseases, suggesting it can be a useful preliminary diagnostic tool for differentiating these conditions.

This study describes a case of generalized trichorrhexis nodosa and finds that defects in alpha-keratin chain formation and low cystine levels in hair may contribute to the condition.

The researchers in this study described the use of trichoscopy to assist in diagnosing aplasia cutis congenita of the scalp in a dark-skinned newborn, noting that trichoscopic findings can differ from those seen in light-skinned patients, yet remain a valuable diagnostic tool.

This article reports a case study of recurrent trichilemmal carcinoma of the scalp, highlighting its clinico-radiological and pathological features, along with its unique characteristics compared to other skin cancers.

This case report of a 60-year-old male patient diagnosed with trichilemmal carcinoma, initially mistaken for a sebaceous cyst, highlights the importance of careful evaluation of atypical swellings for correct diagnosis and treatment.

This article describes how recognizing distinct trichoscopic features aids in diagnosing various dermatological conditions and hair loss, but it reports no new clinical findings.

This article discusses various aspects of trichoscopy for diagnosing hair and scalp disorders and reports no clinical results, offering guidance and highlighting pitfalls for better application of this tool by dermatologists.

The authors report a rare case of trichilemmal carcinoma in the thigh of a 71-year-old, emphasizing the importance of complete surgical excision to prevent recurrence and support patient prognosis.

This study found that hHbl gene expression is localized in the cortical cells of the human hair shaft and is notably high in pilomatricoma cells transitioning to hair shaft keratinocytes.

This review discusses the evolutionary history of keratins and reports no new results, highlighting key events that contributed to the development of mammalian hair and integument.

Advanced imaging techniques are crucial for accurately diagnosing Monilethrix, a rare hair disorder.

This review discusses recent advances in understanding the structural hierarchy of trichocyte keratins, including their heterodimeric structure and distinct conformations impacting hair growth, with no new experimental results reported.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study found that most hair shaft abnormalities can be accurately diagnosed using a handheld dermoscope in a clinical setting.

This study involved using smartphone applications and low-cost trichoscopy devices to assess various hair and scalp conditions, with diagnoses confirmed through detailed imaging during remote consultations and in-person evaluations.

This study reports a case of cystic panfolliculoma, highlighting the role of epithelial-mesenchymal interactions in its pathogenesis and explaining its histological resemblance to trichofolliculoma.

This case report describes a 65-year-old man's trichofolliculoma, a hair follicle-origin tumor, which appeared as a persistent cheek pore extrusion and was removed at the patient's request.

This study found that human hair follicle stem cells formed more colonies and adhered more rapidly, while transit-amplifying cells showed significantly greater mobility.

This review describes distinct trichoscopic findings for various alopecias in individuals with skin of color, but reports no new clinical results.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

This study suggests that human trichohyalin may function as a flexible rod linking keratin intermediate filaments and as a scaffold protein in hair follicle and epidermis cell envelopes.

This article reviews various hair abnormalities observable through trichoscopy in conditions like monilethrix, trichorrhexis nodosa, and ectodermal dysplasias, with no new clinical findings reported.

This study observed that pigmented casts are present in various alopecia types but are not specific to any single diagnosis, with distinct morphological features noted in trichotillomania.

This study suggests that pilomatrixomas' maturation towards areas of shadow cells is linked to a gradual loss of differentiation-specific hair keratins, supporting a hair matrix origin for the tumor.

This report describes a patient with trichothiodystrophy exhibiting both specific hair abnormalities and developmental delay, contributing to the understanding of this rare disorder's clinical presentation.

This study identified several specific trichoscopic features of trichotillomania, with trichoptilosis, V hair, and hair powder being the most frequent findings.

This case report describes an adolescent female with a linear array of trichoepitheliomas on her left neck, highlighting the clinical presentation of this benign tumor.

This study used single-cell RNA sequencing to identify at least nine subpopulations of keratinocytes in human neonatal epidermis, revealing unexpected heterogeneity and complex differentiation trajectories.

This article illustrates various hair shaft defects and suggests that dermatologists can diagnose most of them using light microscopy and polarization without needing advanced imaging techniques.

Hair shaft disorders often indicate genetic or systemic issues and are managed by minimizing damage.
