Other common signs, not just the well-known immune cells around hair bulbs, are important for diagnosing hair loss from alopecia areata.

This review discusses the histologic features of nonscarring alopecia and highlights the importance of clinical-pathological correlation for accurate diagnosis, but reports no new clinical results.

This study found that peripilar signs on the scalp are linked to perifollicular lymphocytic infiltrates in early androgenetic alopecia, detectable even in areas with high hair density.

This review outlines the clinical and histopathological features that aid in classifying tumors arising from the folliculosebaceous apparatus and reports no new research results.

The document concludes that diagnosing hair loss requires evaluating multiple histological features, as no single feature is definitive on its own.

The study observed increased melanin and signs of skin aging in melasma-afflicted skin, with strong CK10 expression in the upper basal epidermis, potentially linked to excessive epidermal cell differentiation and aging.

Clinical signs don't match inflammation levels in lichen planopilaris and frontal fibrosing alopecia.

This review highlights the challenges in identifying histological features of adverse reactions to soft tissue fillers and emphasizes the need for increased awareness due to product uncertainty and delayed reactions.

This study supports the idea that steatocystoma multiplex is a hamartomatous condition and suggests it may be a variant of eruptive vellus hair cyst, both originating in the pilosebaceous duct.

This case report describes the first dermoscopic evaluation of alopecia areata-like disease in a dog, where the condition mirrored human cases in terms of clinical presentation and treatment response.

Eating shiitake mushrooms caused a man to develop a rash similar to a skin condition known as AGEP.

This study observed that scalp melanomas in older men often grow rapidly, appear without pigment, and have more aggressive features compared to other head and neck melanomas.

This case report describes two brothers with an unusual, possibly treatment-resistant inflammatory variant of androgenic alopecia, featuring follicular isthmic lymphocytic inflammation and diffuse central scalp hair loss.

This study identified a new heterozygous mutation in the connexin 26 gene (c.263C>T; p.Ala88Val) in a premature neonate with KID syndrome, who later died from complications.

This study found that human hair follicles demonstrated a dose-dependent response to light in an ex vivo photoepilation model, which could predict the clinical efficacy and permanency of light-based hair removal devices.

This article describes two new cases of granulomatous alopecia areata, a rare variant with few previously reported instances.

Minoxidil doesn't affect perifollicular lymphoid infiltration in alopecia areata patients.

This review discusses histologic findings in alopecia and emphasizes the importance of understanding normal follicular anatomy and cycles in transverse sections, without reporting new results.

This review of 1360 scalp biopsy specimens revealed that 12.5% of cases involved multifactorial alopecia, highlighting the diagnostic complexity of multiple forms of alopecia present in single biopsies.

This article reviews the distinctive features of cutaneous lymphadenoma, a variant of trichoblastoma, and its differential diagnosis, but it presents no new empirical results.

This review discusses the classification of lichen planopilaris and its subtypes under the proposed term "lichenoid alopecias," suggesting they exist along a clinical and histological spectrum.

This review discusses diagnostic tools for scarring alopecias, emphasizing trichoscopy as a low-cost, non-invasive method for more accurate diagnosis, although it reports no new clinical results.

This case report highlights that diagnosing fungal skin infections in immunocompromised patients requires culture for accurate identification, as histologic findings alone can be misleading.

This study found that α-13′-carboxychromanol significantly accelerated wound healing and improved tissue quality in a mouse model, especially when delivered with bacterial nanocellulose under diabetic conditions.

This article outlines the clinical and histological features of milia grouped in plaques on a 59-year-old woman's face but reports no new research findings.

This source outlines the crucial steps and techniques for conducting scalp biopsies to diagnose cicatricial and non-cicatricial alopecias, emphasizing the importance of proper biopsy site selection, technique, and specimen processing to accurately interpret histopathology and understand related hair follicle disorders.

This article reviews various treatment options for diseases associated with cicatricial alopecia but reports no new clinical results.

This paper discusses two preclinical models for studying alopecia areata and finds that testing new therapeutic agents should involve both the C3H/HeJ mouse model and the humanized mouse model for comprehensive insights.

Classifying hair diseases, like alopecia, is difficult and needs more research to understand their causes.

This study found that specific histologic features in skin biopsies can help support a diagnosis of traumatic alopecia (trichotillomania), but not all markers are distinct to the condition.
