This report discusses two cases of porokeratotic eccrine ostial and dermal duct nevus and porokeratotic eccrine and hair follicle nevus, suggesting they may represent a single clinical entity, but reports no therapeutic outcomes.

This study describes five patients with porokeratotic adnexal ostial nevus, a rare skin disorder, highlighting its clinical features and proposing a new encompassing term for related conditions.

This case report describes successful CO2 ablation treatment of porokeratotic adnexal ostial nevus in an 8-year-old boy, with marked improvement over a 12-year follow-up.

This study found HLA and beta 2-microglobulin antigens in various skin structures, with specific localization patterns in keratinocytes and hair follicle components, but not in eccrine or apocrine glands.

This review reports two new cases of porokeratotic eccrine and hair follicle nevus and analyzes all known cases in the Spanish and English literature, suggesting a link to a GJB2 gene mutation.

This study reports that eccrine sweat glands in mice predominantly develop on the footpads, offering a reference for skin research involving genetically engineered mice.

In this study, researchers found that eccrine sweat glands in human scalp skin are morphologically integrated into the pilosebaceous unit, suggesting they form a common homeostatic tissue environment with adjacent structures.

This report describes a case of widespread Porokeratotic eccrine and hair follicle nevus in a 15-year-old woman with keratitis-ichthyosis-deafness syndrome, involving both eccrine ostia and hair follicle infundibula.

A 90-year-old woman's hand lesion was a rare, aggressive skin cancer treated successfully with surgery.

This case report describes a unique presentation of porokeratotic eccrine ostial and dermal duct nevus with lesions on the dorsum of the hand and a focal lichenoid infiltrate, differing from typical palm and sole involvement.

This report describes a rare case of porokeratotic eccrine ostial and dermal duct nevus in a 64-year-old woman, successfully treated with CO₂ laser, highlighting its potential occurrence in older adults.

Small white dots on the scalp seen with a dermoscope correspond to sweat ducts and vary with different hair disorders.

This study found that SSEA-4 is a marker that distinguishes eccrine from apocrine ductal cells in human sweat glands, suggesting its potential use in diagnostic applications.

This study found that adnexal acantholysis does not reliably distinguish pemphigus vulgaris from pemphigus foliaceus, but the level of acantholysis and degree of dyskeratosis serve as distinguishing features among acantholytic disorders.

This review discusses the adnexotropic presentations of interface dermatitides and highlights the importance of recognizing adnexal involvement to aid in accurate diagnosis and avoid misinterpretation.

This study observed that Langerhans cells and melanocytes migrated to hair follicle sites during human embryogenesis, suggesting that Langerhans cells acquire immunoregulatory properties there.

This study observed that in primary extramammary Paget disease, carcinoma commonly spreads to significant depths along hair follicles and eccrine ducts, with a maximal depth of 3.6 mm.

This study identifies key transcriptomic features and a necessary dermal niche for eccrine gland development, advancing potential regenerative approaches for these vital skin appendages.

This study reports that human eccrine sweat gland cells are capable of forming a stratified epidermis, suggesting they may serve as an additional source of keratinocytes for skin repair.
