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

This case report described a 32-year-old woman with plica neuropathica who was diagnosed with schizophrenia after initially seeking dermatological care for her severely matted hair, illustrating a rare presentation of schizophrenia and the importance of considering psychiatric conditions in such cases.

This study examined the complex morphology of the cornified claw sheath in domesticated cats, uncovering structures and growth patterns that help maintain sharp claw tips essential for climbing and prey capture.

The boy had a fungal scalp infection called kerion, which was cured with oral antifungal medication.

This article describes the first documented case of acquired uncombable hair syndrome in a 39-year-old woman, contributing to the understanding of this rare condition.

In this case study, a 15-year-old obese boy was diagnosed with acanthosis nigricans and hair casts in the axillae, with Wood's lamp and dermoscopic examination revealing specific features, yet fungal infection was ruled out through a negative KOH test.

Mice hair follicles take in the amino acid cystine.

This study found that the human hairline is closely linked to several cranial, cerebral, and vascular structures, enabling precise localization of key neuroanatomical landmarks, which could assist in planning neurosurgical procedures.

This study observed that cathepsin L and transglutaminase 3 colocalize in the human hair bulb and nail matrix, suggesting their involvement in terminal differentiation within these epidermal appendages.

This study identified a distinct gene near the hairless locus on chromosome 8p that is responsible for hereditary Marie Unna type hypotrichosis in a German family.

This review discusses the structure and assembly of the cornified cell envelope in stratified squamous epithelial cells and various disorders leading to barrier defects, but reports no new findings.

This study examined uncharacterized CYP21A2 gene variants related to non-classic congenital adrenal hyperplasia and found that several mutations reduce enzyme activity, which may help improve diagnostic and treatment strategies.

The researchers reported increased ubiquitination of proteins such as the insulin receptor in CYLD cutaneous syndrome skin tumors, suggesting that CYLD dysfunction may affect protein secretion and signaling processes.

This study integrated single-cell RNA-seq data from four previous studies to create a comprehensive human corneal cell state meta-atlas, revealing novel marker genes, rare cell states, and distinct transcription factors, and offering a tool to enhance future cornea research.

This review discusses clinical, hormonal, and genetic aspects of nonclassic adrenal hyperplasia and reports no new findings; the condition is highlighted as a potential cause of premature adrenarche and other symptoms in young people.

This case report describes a 6 1/2-year-old girl with significant height growth and early pubic hair development.

This case report details a 17-year-old male with Alopecic and Aseptic Nodules of the Scalp successfully treated with doxycycline and intralesional corticosteroids, highlighting the importance of thorough evaluation for accurate diagnosis.

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.

This article discusses a historical case of a rare skin disorder involving alopecia and follicular plugs reported in 1907; it presents no new findings.

In this case study, a 12-year-old boy with Cushing's Disease experienced a complex diagnostic journey; ultimately, a left-side ACTH-secreting microadenoma was identified and treated with gamma knife therapy, normalizing hypercortisolism but resulting in growth hormone deficiency.

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 case report uncovered that hidden dexamethasone in a dietary supplement caused misleading Cushingoid symptoms and lab results, underscoring the risk of undisclosed ingredients in supplements.

This case study found that a skin lesion in a Samoyed dog did not match any single known follicular cyst or neoplasm type described in the literature.

This case study describes a six-month-old boy diagnosed with Netherton syndrome, featuring ichthyosiform erythroderma and alopecia, possibly linked to aminoaciduria.

This study describes synchronous neonatal telogen effluvium as a physiological phenomenon where newborns exhibit a hair band of rarefaction in the occipital region, not caused by sleeping position.

This study found that human C-tactile afferents respond to hair deflection, suggesting a functionally relevant anatomical relationship to hair follicles similar to that observed in mice.

This study found that cortexolone 17α-propionate showed strong topical antiandrogenic activity, outperforming progesterone and several known antiandrogens, but lacked systemic antiandrogenic effects in animal models.

This study found that CNGC 6, CNGC 9, and CNGC 14 are crucial for maintaining calcium oscillations necessary for normal root hair growth in plants, with mutations leading to defects like swelling and bursting.

This case report documents a rare presentation of congenital milia en plaque on the scalp of a five-year-old boy, with blaschkoid extension to the nuchal area, highlighting its uncommon location and onset.

This study describes how arrector pili muscles form a single muscular structure shared by all hair follicles within a follicular unit at the isthmus level in scalp skin.
