This study found that careful light microscopy using fluid-mounted hair improves detection of the pili annulati phenotype, which varies widely in expression and affects hair fragility.

This case report details the diagnosis of monilethrix in a 4-year-old boy, characterized by brittle hair and specific dermoscopic findings, and highlights the condition's hereditary nature and management through avoiding mechanical hair damage.

This study presents a case of a 6-month-old infant girl with hypotrichosis and an alopecic plaque in the occipital region, characterized by broken and dystrophic hairs with follicular papules and perifollicular hyperkeratosis, suggesting a diagnostic consideration.

In this study, veterinary examinations of 150 domestic canines and felines revealed that M. canis was the predominant dermatophyte, affecting 9 cats and 9 dogs, with dogs showing more severe lesions and higher neutrophil counts in the cytological analysis.

This article reviews two cases of monilethrix in siblings, detailing their clinical and dermatoscopic characteristics, but reports no new findings.

This study found that clinically non-affected perilesional scalp in Japanese alopecia patients often showed microscopic abnormalities, which may help in assessing the spread of disease activities.

This article reviews confocal microscopy findings in trichoepithelioma and desmoplastic trichoepithelioma, noting similarities with histological features, but it provides no new clinical results.

This study identified distinct dermoscopic patterns associated with different types of scalp tumors, highlighting variability in lesions related to patient age, gender, and tumor thickness.

This article reports on a family with six members diagnosed with monilethrix, highlighting varying degrees of alopecia linked to this rare hair shaft defect.

This article discusses the complexities in diagnosing hair shaft disorders and the potential insights hair microscopy can provide, without reporting new clinical findings.

This study found that RCM combined with dermoscopy can differentiate disease states between alopecia areata, tinea capitis, nevus sebaceous, and linear scleroderma of the scalp by identifying distinct dermal and follicular patterns.

This case study describes a 9-year-old boy with monilethrix and associated abnormalities, suggesting a new, severe autosomal recessive variant termed "monilethrix syndrome.

This case report describes a 7-year-old girl diagnosed with multiple eccrine pilar angiomatous nevi, a rare variant of eccrine angiomatous hamartomas, characterized by slow growth and generally benign behavior.

This study found that microRNA levels in hair shafts were significantly decreased in scleroderma patients compared to normal subjects, suggesting they may serve as effective biomarkers.

This report presents a rare case of lichen spinulosus in a 52-year-old woman, featuring hyperkeratotic follicular papules and a dense lymphohistiocytic infiltrate in affected skin areas.

This study observed that trichoscopy of long-lasting lesions in a chronic stage revealed specific features such as absence of follicular openings, cicatricial patches, and thick arborizing vessels.

This study examined dermoscopic features in African-American women with different types of alopecia and found that a perifollicular pink blush, potentially indicating inflammation, was common, particularly resolved with anti-inflammatory treatment, suggesting dermoscopy could aid in management.

Follicular red dots can appear where alopecia areata and vitiligo overlap.

This study used histopathological and ultrastructural analyses to differentiate between junctional epidermolysis bullosa and dermatomyositis-like disease in two juvenile dogs with skin disorders.

The authors observed that the patterned melanoderma on the hairless scalp of fair-skinned Caucasian men with androgenic alopecia resembled similar patterns seen on facial skin.

This paper presents a collection of unusual cases observed over seven years, with detailed histological descriptions but no definitive diagnoses, aiming to encourage further discussion and understanding of the disease process.

This abstract provides no research results, focusing instead on navigation and subscription details for JAMA Dermatology content access.

Polarizing light microscopy can easily and reliably diagnose congenital keratinizing disorders like Netherton syndrome.

This case report describes a pilomatricoma in a 21-year-old woman, highlighting the diagnostic process and illustrating the potential for intraoral surgical access to minimize scarring.

This study found that in patch- and plaque-stage scalp psoriasis, sebaceous gland atrophy and reduced hair follicle size were common but there was no evidence of alopecia.

This case report describes a rare instance of nevus comedonicus with a multi-dermatomal unilateral pattern along the lines of Blaschko, treated unsuccessfully with topical tretinoin and oral retinoids.

This review describes the types of skin lesions associated with systemic lupus erythematosus, discussing their histopathological features, serologic associations, pathogenesis, and prognostic implications.

Hair transplant surgery using micropunch can cause blood vessel damage similar to vasculitis in some cases.

This study observed that cutaneous microwounds created by fractional photothermolysis heal differently from typical wounds, displaying rapid re-epithelialization and limited inflammation, which may help reduce scar formation by delaying collagen remodeling and minimizing myofibroblast activation.
