In this case report, a rare instance of a primary cutaneous granular cell tumor with prominent overlying terminal hair growth in an adult is described, highlighting the importance of recognizing atypical presentations to accurately diagnose similar uncommon neoplasms.

This study concluded that myositis in the reported case was caused by T-cell large granular lymphocytic leukemia, not dermatomyositis.

This case study reports a peculiar variant of an epidermal cyst in a patient, featuring unique characteristics like brownish, lumpy contents resembling bone marrow.

In this study, the researchers reported the detailed anatomical structure of horse skin, including the composition and organization of the epidermis, dermis, and associated glands and follicles.

This study concludes that tiny infundibular cysts, rather than comedones, are the primary lesions in chloracne.

This narrative review discusses advancements in the understanding and treatment of dermatitis herpetiformis as a manifestation of celiac disease and reports no new research results.

This study found that an acne complex animal model using rabbits showed more pronounced clinical symptoms and measured changes compared to the traditional Kligman model.

In this study, researchers found that Notch signaling is crucial for late-stage epidermal differentiation and postnatal hair cycle homeostasis by regulating hair follicle stem cell proliferation and differentiation.

This study found that expression of GDNF and GFR α-1 proteins in human skin decreases with age, particularly in the epidermis, suggesting that their signaling pathways may be altered as people grow older.

This study found that trichohyalin, a protein previously thought to be restricted to hair and tongue, is also present in isolated cells within the granular layer and stratum corneum of normal human epidermis.

This study developed granular hydrogels with reversible interparticle cross-linking, finding they offer high mechanical stability and enhance cell recruitment, making them promising for injectable and 3D printable scaffolds in tissue engineering and therapeutic delivery.

This study examined the expression patterns of various cytokeratins in the outer root sheath of human anagen hair follicles, noting distinct differentiation patterns and localization of keratin markers.

This study found that human trichohyalin has a unique protein sequence potentially contributing to at least three important functions in hair follicle and epidermal cells.

This correspondence highlights existing research on pattern hair loss, discussing findings about immune deposits, lymphocytic infiltration, and responses to treatment, and calls for future well-controlled studies.

This study found that bikunin is expressed in human keratinocytes and may play a role in regulating keratinocyte function during mitosis or inflammation.

This study found that cutaneous stem cells in the basal layer of fetal human skin contribute to the development of the epidermis and hair follicles, with specific marker expressions during different stages of skin development.

In this case study, electron microscopy revealed that harlequin ichthyosis involves giant mitochondria in keratinocytes and abnormal lamellar granule development, which may contribute to pathogenesis through altered lipid metabolism.

This study found that skin sulfhydryl oxidase plays a role in keratinization and may contribute to skin's protective functions, with its expression influenced by irritants and differentiation modifiers.

This study found that CD1d is strongly expressed in human scalp skin and hair follicles, particularly in the anagen phase, suggesting a role in scalp immunology and potential implications for hair disorder treatment.

This research found evidence of inflammatory involvement in androgenetic alopecia, with higher deposition of certain immune components in the scalp of affected patients compared to those without baldness.

This review discusses the pathogenesis of melasma, including genetic, environmental, and hormonal factors, and highlights potential avenues for new treatments and preventive strategies, but reports no new experimental findings.

This study demonstrated that mice lacking skin-specific RXRalpha expression developed hair follicle degeneration and alopecia, indicating the importance of RXRalpha/VDR heterodimers in maintaining hair follicle homeostasis.

A man was diagnosed with a rare form of lupus after showing unique skin symptoms that responded well to treatment.

This article reports that cocaine injections can lead to skin lesions containing talc crystals at the sites of injection.

This study found that medullary cell content in mammal hair evolves from an amorphous form to a biphasic phase, with human and anthropoid hair containing both macrofibrils and microfibrils.

This study evaluated the effects of topical glucocorticoids on human skin using non-invasive imaging methods and observed changes such as alterations in skin layer thickness, keratinocyte size, and collagen and elastin signal intensity.

TEDAR is crucial for skin cell differentiation and barrier formation.

In this study, Dsc 1 was highly expressed in certain layers of fetal epidermis and hair follicle but not in basal cells or oral mucosa, indicating its potential role in maintaining epithelial integrity.

This study found that STRIP1 and the STRIPAK complex play a key role in regulating F-actin and cell-cell junctions, which are essential for maintaining the epidermal barrier in mouse skin.

This study supports the idea that inflammation may play a role in the development of androgenetic alopecia, as indicated by certain immune deposits and porphyrins found more frequently in bald scalp biopsies compared to controls.
