This study identified CD201+ fibroblast progenitors in mouse skin that regulate wound healing through differentiation into specialized cell types, with retinoic acid and hypoxia influencing this process.

This study found that premature desquamation of the inner root sheath is a non-specific histologic feature in scarring alopecia and cannot be used alone to define central centrifugal cicatricial alopecia.

This review highlights the potential of targeting hepatic stellate cell ferroptosis as a treatment strategy for liver fibrosis, underscoring the need for further research into ferroptosis mechanisms in these cells to better understand and combat this condition.

A rare skin condition causes red and dark patches on the face and limbs.

This case study reports a female adult patient with annular elastolytic giant cell granuloma on the scalp, observed through dermoscopy showing multiple yellowish/orange follicular dots against an erythemato-whitish background.

In this study, researchers found that skin pigmentation alterations in a mouse model of Carney complex may be caused by specific dermal fibroblasts promoting melanogenic signaling.

This case report describes a 64-year-old man with pulmonary nocardiosis, where erythema annulare centrifugum lesions possibly associated with co-trimoxazole resolved after discontinuation of the medication.

This study identified a new variety of central centrifugal cicatricial alopecia that includes patchy hair loss on the lateral and posterior scalp in African-American women, which could be misdiagnosed as traction alopecia without dermatoscopy and pathology.

In this study, researchers analyzed skin tumors from patients with CYLD cutaneous syndrome and found that loss of CYLD function is linked to changes in cellular signaling pathways, particularly NF-κB signaling, and leads to increased secretion of specific extracellular matrix proteins.

This review discusses the development, lineages, functions, and roles of fibroblasts in fibrosis across four organs, highlighting their capabilities in tissue repair and contributions to fibrotic disorders when aberrantly activated, but it reports no new experimental findings.

This case report describes a 50-year-old woman with frontal fibrosing alopecia who showed no improvement despite multiple treatments, including intralesional triamcinolone and topical glucocorticoids.

This study reports a case of constrictive pericarditis associated with COVID-19, highlighting the need for imaging, biomarkers, and histology for effective evaluation and treatment decisions.

This research suggests that testosterone-induced expression of TGF-beta1 and type I procollagen may lead to perifollicular fibrosis in androgenetic alopecia, with finasteride inhibiting this process as a possible mechanism for its effects.

In this study, researchers found that CCCA in women of African descent is associated with molecular changes, including dysregulation of fatty acid metabolism and fibrosis pathways, suggesting potential targets for new treatments.

This study observed that mast cells and increased collagen and elastic fibers in the scalp may contribute to male pattern hair loss, but additional research is needed for further understanding.

This study identified two distinct fibroblast subsets in mouse skin, revealing that adult skin scarring occurs due to the repair process utilizing only one, lineage-restricted fibroblast type instead of coordinated diverse populations.

This study investigated various animal tissues from adult mice and embryonic chicks, finding that tissue stiffness follows a sub-linear power law relationship with Collagen-I levels, consistent with cellularized collagen gels but not acellular ones.

A case study reported a 15-year-old boy with a diagnosis of giant folliculosebaceous cystic hamartoma on his right buttock, characterized by malformed hair follicles and sclerotized collagen.

This report describes two patients with ichthyosis linearis circumflexa exhibiting symptoms resembling Netherton's disease, noting multiple hair shaft defects and discussing a possible connection to aminoaciduria.

Mechanical tension worsens keloid scars by activating inflammation and fibrosis pathways.

This case series observed that solitary fibrofolliculoma is a rare lesion that can affect the eyelids, requiring histological examination for accurate diagnosis due to its nonspecific clinical appearance.

This study found that mechanical stress activates a WISP-1/Hedgehog signaling axis that contributes to ligamentum flavum hypertrophy and fibrosis, identifying Hedgehog signaling as a potential therapeutic target.

This study reports a new family with hereditary fibrosing poikiloderma (POIKTMP) and identifies a pancreatic cancer occurrence in a family member, raising questions about FAM111B's role as a potential cancer predisposition gene.

In this study, the introduction of autofibroblasts into ischemic wounds was found to be slightly less favorable for regenerative histogenesis compared to a dermal equivalent with heterofibroblasts, with minor differences in epidermis thickness, collagen fiber area, and blood vessel area.

This study found that fibroblast behavior switching between proliferation and ECM deposition is vital for dermal architecture, where cell migration is primarily important for tissue repair during wound healing.

This article reviews central centrifugal cicatricial alopecia, particularly in women of African descent, and explains its progression and symptoms but provides no new clinical findings.

This review discusses the role of perifollicular fibrosis in androgenetic alopecia and explores potential anti-fibrotic therapies targeting specific signaling pathways, but it reports no new clinical results.

This case report highlights that CCCA can present with multifocal patchy hair loss in younger men of African descent, suggesting the need for careful evaluation when diagnosing atypical alopecia patterns.

This review discusses the role of perifollicular fibrosis in androgenetic alopecia and explores potential treatment strategies targeting fibrotic signaling pathways, but reports no new clinical results.
