This review discusses various nonfollicular scalp conditions causing secondary scarring or permanent alopecia and highlights the importance of specific diagnoses and treatments but reports no new results.

This review examines the interaction between hedgehog and Wnt/β-catenin signalling in hair follicles and basal cell carcinoma, linking Hh pathway inhibition to both tumor regression and alopecia.

This review discusses recent findings on molecular changes in cutaneous adnexal tumours and reports novel markers and pathways involved, highlighting the diverse oncogenic drivers and tumour suppressor alterations.

This review discusses the multifaceted roles of hair follicles in skin health, including potential contributions to skin neoplasias, and reports no new results.

This review discusses the development of targeted therapies for basal cell carcinoma that interfere with Hedgehog signaling and reports no new research findings.

In this study, Far2-/- mice were observed to develop focal alopecia with altered sebaceous gland morphology and lower skin lipid levels compared to wildtype mice.

This study found that T cell-deficient mice developed distinct papilloma phenotypes after MmuPV1 infection, and hyperimmune sera transfer could prevent this infection.

This classification proposal introduces a novel system for categorizing cutaneous adnexal cysts based on their origin in the folliculosebaceous unit and sweat glands, aiming to simplify and enhance understanding of these skin lesions.

This study found that arbuscular mycorrhizal fungus inoculation and shading improved tea seedlings' growth, nutrient absorption, and stress resistance by enhancing root biomass and regulating phytohormone levels and gene expression.

In this study, basal cell carcinoma developed in Ptch-deficient mice only after chemical treatment, not skin wounding, suggesting a second unknown event is necessary for tumor formation.

This study found that the expression of LRIG1 in Merkel cell carcinoma tumors was associated with improved overall and cancer-specific survival.

This study found that circRNA-0100 promotes differentiation of secondary hair follicle stem cells into hair lineage in cashmere goats by sequestering miR-153-3p, which enhances KLF5 expression.

This study found that Hedgehog signaling likely contributes to cervical carcinogenesis, and while itraconazole reduced growth in mice, it did so through pathways other than inhibiting Hedgehog signaling.

This study documented distinct expression patterns of stem cell markers LGR5 and LGR6 in various human skin tumors, highlighting differences in their potential roles and contributions to tumor development.

This study found that hairless mice with homozygous mutations developed significantly more aggressive basal cell carcinomas and a heightened inflammatory response to UVB exposure compared to their haired littermates.

This article discusses the challenges in differentiating between basaloid follicular hamartoma and infundibulocytic basal cell carcinoma, highlighting the need for clarity in diagnosis but reports no new results.

This review discusses various pathologies involving sebaceous glands, primarily and secondarily, but reports no new clinical findings.

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

No genetic link between prostaglandins and hair loss found.

This guide provides a comprehensive approach to diagnosing periocular hair disorders, which can range from benign conditions to those posing serious health risks.

This study suggests that high proliferative activity and peripheral invasion are key indicators of malignancy in canine sebaceous gland tumours. It also reports a higher incidence of circumanal gland and testicular tumours, indicating a possible androgen-related pathway in tumour development.

Higher levels of MiR-92a-1-5p and miR-328-3p found in female hair loss patients.

This study observed two cases of pigmented epithelioid melanocytoma suggesting potential differing origins: one from a hair follicle's outer root sheath and another from an intradermal nevus.

This review outlines a basic diagnostic algorithm to help pediatricians identify causes of hair loss in children, emphasizing early diagnosis and treatment due to the significant psychosocial impact of conditions like alopecia areata and tinea capitis.

This case report describes a 7-year-old girl who developed widespread erythroderma and systemic symptoms after ingesting clobetasone butyrate cream, despite previous psoriasis treatment.

This study observed that 2.5% of patients with mycosis fungoides or Szary syndrome experienced alopecia, predominantly within skin lesions, with scalp metastases from other cancers also potentially causing hair loss, highlighting the diagnostic value of trichoscopy in differentiating alopecia types.

This review provides an overview of the etiology, presentation, and diagnosis of steatocystomas, including subtypes and complications, while detailing their history, epidemiology, and management strategies.

In this case report, researchers detailed a giant proliferating pilomatrixoma in a 36-year-old woman, emphasizing the importance of complete excision to prevent recurrence or potential malignant transformation, distinguishing it from malignancies like angiosarcoma or melanoma.

This study found that skin adnexal tumors are mostly benign, with 98.6% of cases being non-cancerous, and highlighted histopathological examination as essential for accurate diagnosis and management, given their frequent clinical misdiagnosis.

In this study, researchers identified a gene regulatory network in Arabidopsis that controls root hair growth under low-temperature conditions, revealing specific transcription factors and downstream targets that contribute to this growth response despite overall plant development being halted.
