This case report describes the first known instance of fibrosing alopecia associated with cutaneous lichen planus, suggesting fibrosing alopecia may be a variant of lichen planopilaris.

This study demonstrated that epidermal neural crest stem cells and bone marrow-derived stem cells migrated toward inflammatory brain lesions in rats and were successfully tracked using noninvasive MRI.

This report suggests a causal connection between hyaluronic acid filler injections and the development of xanthelasma, possibly through an inflammatory reaction that increases vascular permeability and LDL leakage.

In this study, disruptions in phospholipase A2 activity in Arabidopsis thaliana significantly impaired the plasma membrane localization of PIN proteins, affecting auxin transport and root development.

This review discusses the roles of interferon-γ and PPAR-γ-mediated signalling in scarring alopecia, suggesting these pathways as potential therapeutic targets, but it reports no new empirical results.

This study found that the Verhoeff-Van Gieson stain effectively distinguishes scarred from non-scarred dermis and aids in classifying types of permanent alopecia based on elastic tissue patterns.

This study found that treatment with oral tofacitinib, alone or with other therapies, was associated with clinical improvement in most patients with recalcitrant lichen planopilaris.

In this study, key histologic features such as mucinous perifollicular fibroplasia were identified to aid in the diagnosis of lichen planopilaris.

This study concluded that dermoscopy enhances the diagnostic capability for cicatricial alopecia beyond clinical inspection and identified novel dermoscopic features such as blue-grey dots.

PPAR-γ agonists like pioglitazone may help manage lichen planopilaris but don't fully reverse scarring.

This study reported that mycophenolate mofetil was effective in reducing signs and symptoms of active lichen planopilaris in 83% of patients who had failed multiple prior treatments.

Small white dots on the scalp seen with a dermoscope correspond to sweat ducts and vary with different hair disorders.

The document explains different types of hair loss, their causes, and treatments, and suggests future research areas.

This study demonstrated the expression of type 1 interferon-related proteins in inflammatory lesions of alopecia areata, showing a distinct distribution pattern compared to cicatricial alopecia.

This review discusses the regulatory roles of lysophospholipids like LPA and S1P in diseases such as fibrosis, neuropathic pain, and cancer, but reports no new clinical results.

This report from the UK reviews the literature on post-menopausal frontal fibrosing alopecia and highlights its under-recognition and distinctive characteristics compared to lichen planopilaris, but does not provide new results.

In a study reviewing 291 patients with lichen planopilaris, findings revealed that women were more commonly affected than men, cyclosporine and methotrexate were most effective in achieving remission, and 5-alpha reductase inhibitors and systemic retinoids were particularly beneficial for frontal fibrosing alopecia.

This retrospective review found that while intralesional corticosteroids provided symptomatic improvement for lichen planopilaris, hydroxychloroquine with topical corticosteroids led to higher remission rates but did not result in visible hair regrowth.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

This study found that patients with lichen planus had significantly higher levels of triglycerides, total cholesterol, and LDL-C, and lower HDL-C compared to healthy controls, suggesting an association with dyslipidaemia.

This study introduces the "HoVert" technique, which generates both vertical and horizontal sections from a single biopsy to effectively differentiate lichen planopilaris from discoid lupus erythematosus in alopecia cases.

This study observed that frontal fibrosing alopecia also occurs in men, with clinical features and areas of involvement similar to those seen in women, but often affecting sideburns and facial hair.

This study found that dermoscopy showed distinctive patterns for different types of alopecia, supporting its clinical usefulness for diagnosing diseases with small round or oval hairless patches on the scalp.

In this study, hirsute women with normal or medically normalized testosterone levels experienced similar, though declining, hair reduction from both intense pulsed light and long-pulsed diode laser treatments over six months.

This case series reported that low-dose naltrexone may benefit patients with lichen planopilaris by reducing scalp symptoms and slowing disease progression, with no adverse effects observed in the patients.

This review provides a practical approach to diagnosing pseudopelade of Brocq and updates on treatment options but reports no new clinical results.

This review discusses the role of PPAR-γ in the pathogenesis of primary cicatricial alopecia, including its involvement in lichen planopilaris and treatment trials using PPAR-agonists, and reports no new clinical results.

This study found diverse clinical presentations of lichen planopilaris, with classic lichen planopilaris being the most common, highlighting the importance of recognizing this variability for accurate diagnosis.

This study found that lipid peroxidation products play a clear role in the pathogenesis of skin diseases like psoriasis, vitiligo, and alopecia, but their role in diseases like melanoma and atopic dermatitis remains unclear.

This study found significant differences in serum lipoprotein (a) and triglyceride levels between men with androgenetic alopecia and those with normal hair, suggesting a need for dermatologists to monitor lipid profiles in these patients.
