This review examines histochemical and immunohistochemical markers to differentiate apocrine and eccrine sweat glands, highlighting their distinct markers, though it reports no new clinical findings.

This study reports a case of cystic panfolliculoma, highlighting the role of epithelial-mesenchymal interactions in its pathogenesis and explaining its histological resemblance to trichofolliculoma.

This review discusses the current knowledge on using special and immunohistochemical stains for diagnosing hair disorders, concluding that no stains are recommended for routine use in hair pathology.

This study found that IPL hair reduction led to significant decreases in hair count and thickness by promoting hair follicle miniaturization, increased telogen phase, and reduced cell proliferation.

This study observed that post-surgical use of chlorhexidine digluconate mouth rinse in patients may induce a fibrotic transformation in gingival tissue, promoting a scar-like wound healing response.

This study introduced a new classification system for distinguishing between anagen VI and early catagen stages in human hair follicle organ culture, using it to confirm eflornithine's ability to induce premature catagen.

This guide reviews the biology of sebaceous glands and their evaluation methods, emphasizing their roles beyond lipid production in skin health and disease, and reports no new research results.

This study found that immunohistochemistry can effectively distinguish between tricholemmoma and basal cell carcinoma, with BerEP4 and CD34 serving as key differentiators.

This study found that in individuals with androgenetic alopecia, the expression of apoptosis-related markers differed significantly between affected and unaffected scalp areas.

This study found that IBA-1-immunopositive macrophages in rat skin during wound healing show varied morphometric characteristics and peak in numbers at 2, 6, and 15 days post-injury.

This study found that Sox9 was variably expressed in most canine skin neoplasms, particularly in those originating from the hair follicle's bulge region, suggesting its potential as a stem cell marker.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

This study found that monoclonal antibodies identified distinct staining patterns in benign and malignant skin appendage tumors, highlighting their potential as markers for analyzing skin tumors.

This study suggests that basal cell carcinoma and trichoblastoma may share differentiation toward the hair follicle, as indicated by strong positivity in CK 15, follistatin, and Bmi‐1 markers.

This study reported that the most reliable way to differentiate alopecia areata from androgenic alopecia is by detecting intrafollicular CD3 and CD8 cell density, with CD3 being the most specific and sensitive marker.

This study found that, in female patients with pattern hair loss, injections of adipose-derived stem cells increased hair density and thickness, reduced perifollicular inflammation, and enhanced markers associated with hair cycle regeneration.

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 observed that alopecia areata patients had significantly lower levels of hair follicle stem cell markers SOX9 and CD34 in affected skin samples, correlating with disease severity and recurrence, suggesting potential impairment in hair regeneration.

This study found that administering lycopene to rats provided significant protection against the testicular damage caused by finasteride, as indicated by improved sperm parameters, and reduced oxidative stress and apoptosis markers.

In this study, the immunohistochemical and lectin binding profiles of basal cell carcinoma closely resembled those of the outer root sheath of vellus hair follicles, suggesting a potential histochemical relationship.

This study identified high expression of the Sur2A subunit in cancerous cells in two animal models, highlighting a potential drug target in breast and renal cancers, with additional pharmacovigilance data linking KATP channel genes to varied cancer risks.

In this case report, a rare melanotrichoblastoma tumor was identified in a 51-year-old female following the histological and immunohistochemical analysis of a lesion on the pubo-inguinal area, presenting with strong epithelial marker positivity and a low proliferative index.

This study reports various immunophenotypical patterns in apocrine mixed skin tumors, resembling the structures of hair follicles, sebaceous glands, and apocrine glands.

This study found that combining platelet-rich plasma therapy with minoxidil was more effective in treating androgenetic alopecia in men than either treatment alone.

This study found that calretinin immunoreactivity may help identify the innermost cell layer of the outer root sheath in anagen hair follicles and certain cutaneous adnexal proliferations with follicular, sebaceous, and eccrine differentiation.

This study found that immunohistochemistry for calretinin may identify certain cutaneous adnexal tumors with follicular differentiation towards cells of the outer root sheath.

In this study, hyperplastic layers of scabietic sheep skin showed expansive keratin labeling, indicating altered keratin expression compared to healthy skin.

This study found that CD90+ stem cells with fibroblast-like morphology are present in the lower part of the anagen hair follicle in dogs.

This study suggests that sweat glands may have an immune privilege similar to hair follicles, and disruptions in this could contribute to autoimmune skin diseases.

This study found that CD90+ cells, resembling mesenchymal stem cells, are abundantly present in the lower part of anagen hair follicles in dogs.
