This review discusses the mechanisms associated with protoporphyrin IX in living cells and reports no clinical results; the authors emphasize its potential in cancer diagnosis and the risks of toxicity.

This reference list, part of a book by Alex Gough, Alison Thomas, and Dan O'Neill, compiles citations from veterinary journals on various canine and feline health issues, but reports no new research findings.

This study found that biallelic mutations in the TTC7A gene affect lymphocyte and gut epithelial cell function, thereby contributing to the development of inflammatory bowel disease in patients.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

This report describes a rare case of severe combined immunodeficiency caused by a FOXN1 gene variant, complicated by Epstein-Barr virus infection and high-grade B-cell lymphoma, leading to the infant's death despite treatment efforts.

This index of Harper's Textbook of Pediatric Dermatology, Fourth Edition, provides no clinical results or new findings.

This article reviews the role of factor Xa inhibitors like Rivaroxaban and suggests they may eventually replace vitamin K antagonists, but their side effects require further clarification.

In this study, researchers suggested that adipose-derived exosomes could be a promising treatment option for lichen planopilaris, particularly in cases resistant to standard therapies, by potentially aiding in symptom management and hair preservation.

This case report highlighted an instance of lichen spinulosus emerging as a new cutaneous sequela in a boy following toxic epidermal necrolysis, responding to treatment with ammonium lactate.

This study suggests that combining tranexamic acid with low-dose oral retinoids may offer moderate to good improvements for lichen plan pigmentosus, although larger trials are needed for confirmation.

This study introduced the Lichen Planus Activity and Damage Index (LiPADI), which effectively assesses the severity and progression of lichen planus, aligning well with other clinical indicators.

This study reports that a patient with rare linear lichen planopilaris experienced complete hair regrowth after 12 weeks of treatment with the antibody ixekizumab, suggesting it as a potential targeted therapy.

This case report highlights the complexity of lupus erythematosus/lichen planus overlap syndrome, noting a high potential for progression to systemic lupus erythematosus.

In this case report, a 53-year-old woman with Little-Graham-Piccardi-Lassueur-Syndrome responded well to a treatment regimen of hydroxychloroquine, methotrexate, and other therapies, effectively halting the progression of this rare dermatosis characterized by alopecia and hyperkeratotic eruptions.

In this study, researchers investigated the role of the ATX-LPA axis in asthma pathogenesis using human and mouse models and highlighted the potential for developing new ATX inhibitors as effective asthma treatments.

This study reports two cases of follicular lichen planus, suggesting that GLPLS and LPP may be variants of this condition based on clinical and immunofluorescent findings.

This study found that activating liver X receptors with an agonist reduced skin fibrosis in experimental models, particularly in inflammation-driven conditions, by inhibiting macrophage infiltration and interleukin-6 release.

This study found that the transcription factor Lhx2 regulates Sonic Hedgehog signaling in mouse retinal progenitor cells, mainly by controlling the expression of co-receptors essential for effective pathway activation during early retinal neurogenesis.

A 70-year-old woman with a rare skin condition improved after treatment with topical steroids and acitretin.

An 8-year-old girl developed a rare skin condition in a linear pattern on one side of her body after a lung infection, which improved with treatment.

This study found that in early retinal neurogenesis in mice, the transcription factor Lhx2 regulates Sonic Hedgehog signaling by controlling expression of pathway genes like the co-receptors Gas1 and Cdon.

In this research, RNA expression analysis of scalp biopsies from lichen planopilaris patients revealed changes in specific genes after treatments with hydroxychloroquine, narrow band UVB, or low level laser light therapy, suggesting potential biomarkers and implicating M2 macrophages in the disease's immunopathogenesis.

This study reports the first known case of linear lichen planopilaris following Blaschko's lines in a nonfacial region.

In this case report, a rare form of chronic cutaneous lupus, lupus erythematosus profundus, was treated effectively with topical and systemic therapies, leading to improvement and healing of ulcerations, though resulting in atrophic scars and macules.

This review synthesizes the diverse roles of the transcription factor LHX2 in development, tissue maintenance, and injury repair across various organ systems, highlighting its potential therapeutic applications and significance in regenerative medicine, particularly in developmental disorders and tissue regeneration.

This study suggests that fractional infrared technology may effectively improve cervical skin laxity by enhancing dermal thickness without adverse effects in a small pilot group.

This narrative review discusses lichen planus pigmentosus, including its variations, associated triggers, and management strategies, but reports no new clinical results.

This case report suggests that exosome therapy may offer a promising alternative treatment for lichen planopilaris, showing potential benefits in hair regrowth, reduced inflammation, and improved scalp condition, but further studies are needed to confirm long-term efficacy and safety.

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.

A new genetic mutation causing Xeroderma Pigmentosum was found in an 8-year-old girl, affecting her DNA repair.
