This article discusses androgenetic alopecia in Amerindian Mapuche people from southern Chile and reports no new clinical findings.

This study suggests that proteins CHI3L1 and CXCL5, secreted by recovery-state dermal papilla cells, may promote hair growth by stimulating the proliferation of outer root sheath cells.

This study reports a rare case of a 40-year-old woman with multiple calcified trichilemmal cysts, associated with alopecia universalis and suggesting a potential genetic link.

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 documented clinical cases of dermatophytosis in two free-ranging southern chamois in the Eastern Pyrenees, with Trichophyton mentagrophytes identified in both animals.

This case series suggests that EE/CMA 0.03mg/2mg may help manage dermatological disorders related to androgen excess, as evidenced by symptomatic improvements in the four patients treated.

This study suggests that NBCCS and BFHS may be the same genetic condition, which could help improve identification and management of misdiagnosed cases with specific surveillance strategies.

This study provides suggestive evidence that duplications in the MCHR2 gene may be involved in the pathogenesis of alopecia areata.

This study found that the lipid composition of the epidermis varies significantly throughout the hair growth cycle and after applying methylcholanthrene, with notable differences observed between hyperplastic and carcinomatous conditions.

The researchers in this study described the use of trichoscopy to assist in diagnosing aplasia cutis congenita of the scalp in a dark-skinned newborn, noting that trichoscopic findings can differ from those seen in light-skinned patients, yet remain a valuable diagnostic tool.

This study found that applying a mix of cholesterol and Tween 60 detergent to mouse skin significantly reduced epidermal cell mitotic activity.

This report describes an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman, differing from its typical presentation in elderly women.

In this study, chemotherapy-induced alopecia in cancer patients showed specific trichoscopic patterns and abnormal hair shaft morphology, suggesting intermittent follicle damage from chemotherapy, but larger studies are needed for confirmation.

This study found that impairments in cholesterol biosynthesis in hair follicles of primary cicatricial alopecia patients trigger an inflammatory immune response, potentially linking sterols to inflammation in the disease's pathogenesis.

This review discusses diagnostic and treatment considerations for women with cutaneous hyperandrogenism, noting therapeutic options are more effective for hirsutism and acne than for androgenetic alopecia, but reports no new clinical results.

Long-standing benign tumors can become cancerous, especially in people with weakened immune systems.

This study found that ossification in trichilemmal cysts may be more common than previously thought, often associated with cyst wall rupture, and reports a novel case of ossifying TC with extramedullary hematopoiesis.

In this study, ketoconazole treatment successfully cured a dog with erythematous epilation caused by Chaetomium globosum, with new hair growth observed 9 weeks later.

In this case study, a 20-year-old man experienced progressive hair loss starting as a localized patch on the vertex of his scalp, eventually spreading in a curvilinear pattern to the sides and back.

This case report describes a middle-aged man with a growing scrotal mass, diagnosed as a benign proliferating trichilemmal tumor, which can mimic squamous cell carcinoma, highlighting the importance of correct diagnosis.

This article is a letter to the editors about a novel observation regarding chemotherapy-induced alopecia and does not include an abstract with new research results.

This case report describes a 2-year-old boy diagnosed with trichothiodystrophy, characterized by fragile hair, intellectual damage, diminished fertility, and short stature.

This study reported that both drospirenone and chlormadinone acetate oral contraceptives had similar beneficial effects on clinical, metabolic, and hormonal parameters in women with polycystic ovary syndrome over six months.

This study examined dermoscopic features in African-American women with different types of alopecia and found that a perifollicular pink blush, potentially indicating inflammation, was common, particularly resolved with anti-inflammatory treatment, suggesting dermoscopy could aid in management.

This study confirms that scalp hair follicles in Chilean subjects exhibit seasonal variations, with a higher percentage of follicles in the telogen (resting) phase during the summer compared to the winter.

This study reports two cases of trichoblastic neoplasms with histologic features suggesting they may be distinct, locally aggressive trichoblastic carcinomas separate from basal cell carcinoma.

In this study, researchers describe a rare case of trichoepitheliomas in a 7-year-old boy, characterized by multiple skin lesions in a Blaschko-linear pattern, hypothesizing it as a type 1 segmental mosaicism without detected CYLD gene mutations.

This study identified a germline variant in PLCD1 as a major risk allele for familial trichilemmal cysts, requiring a subsequent somatic mutation in the same allele for cyst formation.
