This case report of a 60-year-old male patient diagnosed with trichilemmal carcinoma, initially mistaken for a sebaceous cyst, highlights the importance of careful evaluation of atypical swellings for correct diagnosis and treatment.

This study observed dynamic changes in CD10 and CD34 expression in fetal and adult human hair follicles during embryogenesis and hair cycling.

This study used melamine formaldehyde particles to measure a pH gradient along the hair shaft, showing a significant pH decrease from the hair sheath to the external shaft.

In this study, irreversible alopecia on the crown of the scalp in Black women using hot combs was associated with chronic inflammation and follicle damage leading to scarring.

In this study, researchers identified a form of irreversible scalp alopecia in Black women using hot combs, characterized by incomplete hair loss primarily on the crown and follicular scarring.

This study found that aged tritiated thymidine breaks down and incorporates into cytoplasmic macromolecules, not DNA, suggesting caution in its use.

This study found that cationic lipid-based formulations enhanced the delivery of large molecules into hair follicles in human scalp skin, with potential to reach pharmacologically active concentrations in the hair bulb.

This study observed morphological changes in scalp hair follicles of humans deprived of protein for 15 days, which suggests potential use in diagnosing protein-calorie malnutrition.

This study identified the presence of apoptotic or necrotic keratinocytes and hair shaft dystrophy as potential markers of hair loss in patients with HIV-1 infection.

This study found that the use of hot combs with petrolatum in Black women causes irreversible alopecia limited to the crown of the scalp, resulting in follicular scarring.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

This correspondence describes two patients with both epidermolysis bullosa simplex, Dowling-Meara type, and loose anagen hair syndrome, an association not previously reported in the literature.

In this study conducted at the Veterinary Clinical Complex in Bikaner, Rajasthan, researchers found that among 240 canine dermatitis cases, 25 dogs had demodicosis, characterized by various hematological and serum biochemical changes, and distinctive histopathological alterations in skin samples.

This study found that in patients with non-cicatricial alopecia, hair follicles and their sheaths were thinner compared to controls, especially in cases of alopecia areata and telogen effluvium, with notable thinning beginning in the subcutaneous fat tissue.

This article reports a case study of recurrent trichilemmal carcinoma of the scalp, highlighting its clinico-radiological and pathological features, along with its unique characteristics compared to other skin cancers.

This case report described a facial hairline tumor initially diagnosed as a sebaceous cyst but ultimately confirmed as a rare Proliferating Pilar Tumor with focal malignancies upon histopathological examination.

This study found that treating sheep hair follicles with IGFⅠ and EGF stimulated growth, with EGF also accelerating cell differentiation and altering the growth cycle.

In this study, researchers found that patients with non-scar alopecia exhibited thinner hair sacs and root sheaths compared to a control group, with significant thinning observed in cases of alopecia areata.

This study found that the transcription factors Msx2 and Foxn1 are crucial for maintaining Notch1 expression in the hair follicle matrix, which is necessary for proper hair differentiation.

This study found that the Gsdma3 gene is necessary for normal hair follicle differentiation in mice, with its mutation leading to progressive hair loss and defects in hair structure.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

Syphilitic alopecia is a rare hair loss condition in secondary syphilis that looks similar to another condition but can be diagnosed with specific tests and responds to antibiotics.

This study applied a new RGB trichrome stain to human skin samples, revealing distinct structural staining in normal tissues and potential proteoglycan-rich zones in hair follicles.

In this study, proliferative and necrotizing feline otitis externa in four domestic shorthair cats improved with topical 0.1% tacrolimus treatment, despite previous ineffective therapies.

This study reports an unusual finding of plucked anagen hairs with intact hair papilla and connective tissue sheath in various scalp disorders, suggesting further documentation is needed.

This study found that anisotropic osmolyte solutions may improve hair follicle turnover and condition in both in vitro and in silico models, as well as in human volunteers with hair disorders.

This paper reports on the structural characteristics of α-type filaments in the inner root sheath cells of guinea pig hair follicles without presenting new clinical findings.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.
