This case report describes a patient with lichen nitidus whose lesions improved following treatment with oral astemizole and topical steroids, although spontaneous resolution remains a possibility.

This review discusses the cell biological characteristics of the outer root sheath of normal human hair follicles and highlights some similarities and differences with trichilemmal tumors, but reports no new results.

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

This case study identified the condition as Monilethrix in a 17-year-old female, characterized by a beaded hair appearance and linked to a genetic cause.

This study presents a microscopic analysis of the pruritic variant of trichostasis spinulosa in two patients and reviews existing literature, reporting no new clinical results.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

The hair follicle structure is more complex than thought, with new findings on protein formation.

This report describes four trichoblastoma cases rich in Merkel cells, suggesting these tumors may mimic fetal skin development where Merkel cells are numerous.

This article reviews the use of trichoscopy for diagnosing common hair and scalp diseases and introduces a new classification for specific skin surface abnormalities, without presenting new clinical results.

This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

This study suggests that immunohistochemistry of keratin and involucrin expression can aid in distinguishing malignant trichilemmoma from other tumors previously diagnosed as such.

This report describes an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman, differing from its typical presentation in elderly women.

This study identified trichohyalin as an early differentiation marker in hair follicles, with potential structural roles related to alpha-helical formations, based on the partial characterization of its cDNA in sheep.

This study suggests that uncontrolled embryonic trichogenesis may play a role in the development of trichoblastoma in rabbits.

In this study, researchers identified elongated corkscrew hairs as a new trichoscopic pattern in immunosuppressed adults with chronic endothrix tinea capitis, which may help in earlier diagnosis and targeted mycological investigation.

In this case report, researchers observed multiple trichofolliculomas in family members, noting this as a rare manifestation of typically singular hair follicle hamartomas.

This study found that trichostasis spinulosa was present in some seborrheic keratoses, indicating they may partly originate from hair follicle cells.

This report describes a case of trichostasis spinulosa, a condition with pruritic, black papules on the face caused by keratotic plugs with embedded vellus hairs.

This study reported detailed three-dimensional ultrastructural observations of human hair and hair follicles using a modified preparation method, including morphological differences in hair bulb cell layers and surface projections on root sheath cells.

This article discusses a historical case of a rare skin disorder involving alopecia and follicular plugs reported in 1907; it presents no new findings.

This study compared trichostasis spinulosa with keratosis pilaris and eruptive vellus hair cysts, finding differences in lesion distribution and microscopic appearance.

This article discusses the use of trichoscopy as a helpful tool for early diagnosis and monitoring of dissecting cellulitis, but it reports no new clinical results.

This case report describes an uncommon occurrence of trichofolliculoma in a 64-year-old male, which was easily treated through simple excision.

This study examined developing hair cortex with electron microscopy and found that keratin fibrils form between specific regions in hair follicles and aggregate into twisted cables.

This study found that trichoscopy is a useful tool in differentiating between alopecia areta and trichotillomania on the eyebrows based on distinct hair and follicle features.
