This case report describes a trichofolliculoma with perineural invasion, highlighting a rare and clinically significant finding in a typically benign hair follicle tumor.

This study observed that the thinning and structural abnormalities in monilethrix-affected hair occur at the internodes due to possible periodic dysfunction of the hair matrix, particularly in the cortex.

This study established standard trichoscopy norms for adult white females, providing benchmarks for hair thickness, percentage of thin hairs, and pilosebaceous units with single hair across different scalp areas.

This research found that a monoclonal antibody (MAb 17) specifically reacts with certain subunits of trichocyte keratin in rats, and discovered that trichocyte keratin expression in hair and whiskers begins at different embryonic stages.

This study found that the transcription factor Trps1 acts as a novel regulator of the Wnt signaling pathway and early hair follicle progenitors in developing vibrissa follicles in mice.

This study found that eosinophils are a useful diagnostic feature for alopecia areata, especially when the typical "swarm of bees" lymphoid infiltrate is absent, helping differentiate it from trichotillomania.

In this case report, a 65-year-old man's neck lesion was initially misdiagnosed as benign but later identified as trichilemmal carcinoma, with the authors recommending Mohs Micrographic Surgery as the preferred treatment option for this rare condition.

This case report describes a 26-year-old male patient with trichofolliculoma, highlighting dermoscopic features that aid its diagnosis and distinct characteristics from other similar lesions.

This article discusses monilethrix, a rare human hair dysplasia caused by mutations in hair keratins, but reports no new clinical findings.

This study describes a method for serially cultivating adult human hair follicle keratinocytes using a specific growth substrate and cryogenic storage, enabling subculture and immunofluorescence studies.

This article discusses the utility of trichoscopy in distinguishing hair disorders with similar clinical appearances but reports no new clinical results.

This study reviews the use of trichoscopy in diagnosing and monitoring alopecia areata, highlighting that certain trichoscopic findings like yellow and black dots, exclamation mark hairs, and others, provide valuable insights into disease status and treatment response.

This report presents the first known case of a proliferating hybrid cyst containing both epidermoid and trichilemmal components on the scrotum of a 44-year-old man.

This study suggests that trichoscopy with a handheld dermatoscope may help differentiate temporal triangular alopecia from other localized alopecia by identifying specific hair features.

Fungi-produced compounds can change plant root growth.

This study found that different stabilizing mutations in Aux/IAA proteins affect root hair development in Arabidopsis by disrupting the auxin response and suggest a model where the relative abundance of these proteins determines root hair initiation.

This research suggests that the barley protein RACB supports cell polarity functions rather than interfering with immunity, as it aids nucleus positioning during fungal attack rather than affecting early immune responses.

This review discusses the role of PIN-FORMED 2 and related signaling pathways in root hair growth regulation and reports no new experimental findings.

The researchers reported that in Arabidopsis collet hairs, nuclear positioning near the cell tip is not essential for hair growth, although it correlates with growth dynamics.

This review examines the role of root hair specification and nutrient acquisition in plants, emphasizing the need for further genetic research to understand the mechanisms influencing root hair development and growth.

In this study, researchers found that the efflux of calcium in root hairs of Arabidopsis thaliana, particularly through the ER-localized ACA2 and ACA7, is crucial for modulating cytoplasmic calcium signals and enabling proper root hair growth, with disruptions leading to impaired elongation.

This study experimentally validated Lockhart's viscoplastic framework for tip growth in Arabidopsis root hairs by demonstrating alignment with observed growth rates and estimating yield turgor pressure and cell wall viscosity, offering a methodology adaptable to other species and conditions.

Among maize plants, this study observed that root hairs tend to grow in air-filled pores at the root-soil interface, but their growth into the soil matrix is limited, posing potential constraints on nutrient uptake, anchorage, and rhizosheath formation.

This study found that the peach gene CTG134, involved in auxin-ethylene interactions, plays a role in hormonal regulation during root hair formation in Arabidopsis and tobacco.

This study detailed the structure and amino acid composition of sheep trichohyalin, noting its presence in various tissues and suggesting a possible functional role beyond structural support in hair follicles.

This article discusses trichotillomania and trichoteiromania, focusing on their clinical presentation, main trichoscopic features, and similarities in hair loss patterns but reports no new research findings.

This case report describes an 89-year-old woman with a recurrent benign proliferating trichilemmal tumor on her back, highlighting its misdiagnosis as a sebaceous cyst and successful excision with free margins.

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 case report documents a rare instance of a trichilemmal cyst occurring on the plantar surface of the foot, highlighting the necessity of histological examination for accurate diagnosis when clinical or radiological presentations are atypical.

This study observed that trichoscopy can identify specific patterns in alopecia areata, such as white and black dots, which assists in non-invasive diagnosis and assessing disease severity.
