This study found that, in Japanese patients with androgenic alopecia, sebaceous glands exhibit increased multilobulation which may be significant in the condition's pathology.

This review discusses dissecting cellulitis of the scalp and reports no new clinical findings.

This study found that simultaneous presence of specific and nonspecific skin lesions, or having three or more types of skin lesions, was associated with increased systemic activity of systemic lupus erythematosus.

This study reports previously unreported nail features in Cronkhite-Canada syndrome, specifically recurrent onychomadesis of all 20 nails linked to systemic illness.

This article discusses dissecting cellulitis of the scalp, an uncommon hair condition, and reports no new clinical results; recent terminology adjustments are noted for potential overlaps with other follicular diseases.

This study supports the idea that steatocystoma multiplex is a hamartomatous condition and suggests it may be a variant of eruptive vellus hair cyst, both originating in the pilosebaceous duct.

This case report describes a patient with Clouston Syndrome who developed eccrine syringofibroadenoma, marking only the fourth such association documented in existing literature.

In this study, researchers analyzed alpaca skin morphology and found that type I and IV collagen are present in both the epidermis and dermis, while type III collagen is found only in the dermis.

The document describes various skin conditions, their features, and treatments but lacks detailed study size information.

This study focused on equine sarcoid, the most common tumor in horses, and described its types, clinical signs, and histopathological characteristics such as hyperkeratosis and changes in the hair follicle and dermis.

This article discusses eruptive vellus hair cysts, describing their clinical characteristics, and reports no new research findings.

In this study of folliculitis decalvans, researchers found that compound follicular structures in scalp biopsies are primarily composed of terminal anagen follicles, surrounded by fibrosis and inflammatory cell infiltrate, which could enhance understanding of this condition.

This case report describes a 9-year-old Korean boy with a calcified nodule on his earlobe, confirmed by histopathologic examination and Von Kossa staining.

This study found that cutaneous myxomas showed decreased CD44 expression in follicular epithelial proliferations, which may be related to abnormal hyaluronate accumulation in these lesions.

Capitate trichomes have more endoplasmic reticulum and vacuoles, while peltate trichomes have more plastids and larger subcuticular spaces.

Mouse tail skin has different keratinization near hair follicles and scales.

In this study, researchers found that alpha-keratin homologs similar to those in mammalian hair are present in the claws of the lizard Anolis carolinensis, suggesting a structural role during claw formation.

This study observed inflammatory and granulomatous infiltration in alopecic nodules of the scalp and suggested that AANS should be considered in diagnoses of alopecic nodules.

This report reviews familial cases of aplasia cutis of the scalp, noting large irregular defects at the vertex or anterior along the sagittal suture in six families.

This study found that dermal papillae in alopecia areata, including clinically normal follicles, exhibited ultrastructural abnormalities that suggest an early pathological role in the disease's development.

This study found that while malignant pilomatricomas maintain some keratin expression patterns seen in benign counterparts, they notably express additional epithelial keratins, potentially influencing tumor calcification.

This study identified biallelic variants in the LSS gene as a possible genetic cause of palmoplantar keratoderma-congenital alopecia syndrome type 2, highlighting the role of cholesterol synthesis in skin cornification.

This study found that experimentally induced calcification in rat skin led to rapid and localized mineralization in hair follicles, progressing to more extensive calcification with prior hypercalcemic treatment.

This case report describes a pilomatricoma in a 21-year-old woman, highlighting the diagnostic process and illustrating the potential for intraoral surgical access to minimize scarring.

This study provides conclusive evidence of exogenous calcium fatty acid deposits forming between the cuticle layers in hair, affecting its optical and mechanical properties.

This case report describes a 52-year-old black woman with diffuse scalp swelling and thinning hair attributed to a large increase in the thickness of scalp subcutaneous fatty tissue.

This chapter reviews fungal skin diseases in cattle and reports no new findings; the authors discuss conditions like sterile eosinophilic folliculitis and anagen defluxion, noting their patterns and effects.

This case report describes a patient with untreated lepromatous leprosy developing Lucio's phenomenon, highlighting difficulties in distinguishing it from erythema nodosum leprosum with vasculonecrotic lesions.

In this study, the vitamin D analogues 1 alpha,25-dihydroxy-vitamin D3 and calcipotriol were found to thin the living cell layer and affect differentiation marker expression in organotypic cultures of human outer root sheath cells.
