This case report of a 60-year-old male patient diagnosed with trichilemmal carcinoma, initially mistaken for a sebaceous cyst, highlights the importance of careful evaluation of atypical swellings for correct diagnosis and treatment.

This study found that Notch signalling promotes differentiation of epidermal cells and acts as a tumour suppressor in the skin by interacting with various pathways and mechanisms.

This review discusses the experimental targets of fetal wound healing and evaluates existing therapies for scarless healing in adult skin, but reports no new research findings.

This study highlights the evolving understanding of acne's pathophysiology and suggests that targeting pro-inflammatory cytokines such as IL-1β, IL-17, IL-23, and TNFα with biological antibodies may offer new treatment strategies for severe acne and its scars.

This study found that a newly developed injectable hydrogel combined with human umbilical cord-mesenchymal stem cells significantly accelerated wound healing and reduced inflammation in full-thickness cutaneous wounds.

In this study, researchers demonstrated that the expression of the oncogene SmoM2 leads to basal cell carcinoma in the ear epidermis of mice but not in the back skin, with differences in susceptibility linked to the composition of the extracellular matrix.

This study found that UV-B exposure significantly increased the expression of inflammatory cytokines IL-1β and IL-8 in cultured sebocytes.

This study found that skin mesenchymal stem cells from hidradenitis suppurativa patients overexpress proinflammatory and anti-inflammatory cytokines, suggesting their potential contribution to the disease's pathogenesis.

This study describes a case where stopping infliximab and using oral minocycline with topical treatments effectively resolved alopecia and scalp psoriasis in a woman with Crohn's disease.

This case report details the immunohistochemical study of cytokeratins in a trichofolliculoma, providing insights but no new clinical findings.

This study found that the spermidine analog N1-methylspermidine prolonged hair follicle growth and decreased inflammation and oxidative stress in cultured hair follicles, suggesting potential relevance for treating inflammatory scalp diseases.

This study found that intracellular Toll-like receptors were significantly up-regulated in peripheral blood mononuclear cells of alopecia areata patients, suggesting a potential role in inflammatory signaling and pathogenesis.

This study found that reducing testosterone levels in male mice accelerates wound healing and decreases inflammation, suggesting a potential therapeutic target for improving wound repair in elderly males.

This review reports no new results but highlights the secretory function of keratinocytes, focusing on how various secretions, notably growth factors, impact stem cell differentiation into keratinocytes.

This study observed that exosomes from adipose-derived stem cells promoted hair growth by enhancing dermal papilla cell proliferation and activating signaling pathways, suggesting potential for treating immune-mediated alopecia.

Different stem cells have benefits and challenges for tissue repair, and more research is needed to find the best types for each use.

The document outlines criteria to identify and differentiate neoplasms based on follicular characteristics.

This study mapped the development of the human pilosebaceous unit in prenatal scalp skin using multi-modal analysis, finding that epithelial-mesenchymal interactions guide cellular fate and validated tissue-patterning through a hair-bearing skin organoid model.

This review highlights Malassezia's dual role as both protective and pathogenic within the hair follicle ecosystem, noting its involvement in skin disorders and potential cancer progression, and calls for further studies to develop targeted treatments for related conditions.

In a mouse model, this study found that exposure to PM2.5 leads to significant postpartum hair loss, apparent via morphological changes and elevated markers of inflammation, apoptosis, and fibrosis, potentially exacerbated by changes in hormone receptors and stem cell populations.

This case study describes a middle-aged woman diagnosed with a proliferating trichilemmal tumor on her scalp, emphasizing the importance of comprehensive diagnostic approaches and highlighting surgical excision as the primary treatment.

This case report identifies necrolytic migratory erythema associated with a glucagonoma in a 40-year-old man, presenting with distinct skin lesions, weight loss, and diarrhea.

This study reports a case of a woman with Cushing's disease whose initial complaint was hair loss, a rare presenting symptom, despite multiple dermatological signs like easy bruising and violaceous striae being more indicative of the condition.

This study found that overexpression of the enzyme ornithine decarboxylase in transgenic mice led to UVB-induced skin tumors, but this was prevented by the ODC inhibitor α-difluoromethylornithine.

This paper discusses the role of Runx1 in epithelial biology and pathology, highlighting its dual function as a tumor promoter and suppressor in different contexts, and reports no new experimental findings.

This article reports on three new cases of Birt–Hogg–Dubé Syndrome and emphasizes the role of genetic analysis in its diagnosis due to clinical challenges.

This report diagnosed a mass below a dog's eye as desmoplastic tricholemmoma based on histopathological and immunohistochemical findings.

This study found that inhibiting the HEDGEHOG-GLI1 pathway could reduce keloid size and gene expression, suggesting it as a potential therapeutic target for keloid pathogenesis.

This review discusses the biology of antiandrogens and highlights available bioassay models to predict their therapeutic effects on human skin, reporting no new clinical results.

The document concludes that early diagnosis and treatment are crucial for managing skin diseases in ferrets.
