In this case study, a 69-year-old male with a neck swelling was diagnosed with a trichilemmal cyst, highlighting the importance of complete surgical excision for lesions with proliferative or malignant potential.

This study suggests that a position effect disrupting TRPS1 expression may be linked to hypertrichosis in both Ambras syndrome in humans and a similar phenotype in Koa mice.

This study found that trichorrhexis nodosa, a common cause of unexplained hair loss, is primarily caused by trauma rather than a metabolic defect.

This review examines the roles of Hedgehog and Gli proteins in mouse embryonic mammary development and suggests that Gli3-repressor-mediated off-state of Hedgehog signaling determines mammary fate over hair follicle fate.

In this case report, a 17-year-old male with a specific TRPS1 gene mutation presented with sparse, soft hair, short thumbs and toes, misaligned teeth, and distinctive bone abnormalities in the fingers and toes as observed through X-ray analysis.

This study suggests that hair loss and reduced arterial blood flow after hyaluronic acid filler injection in the temporal region may result from arterial compression rather than intra-arterial occlusion.

This report introduces a new potential sign, paired ear creases of the helix, which may have relevance to cardiovascular disease similar to diagonal ear lobe creases, in a case of coronary artery disease.

This study found that microbotox, especially when injected intradermally, effectively reduces enlarged facial pores with higher patient satisfaction and longer-lasting results compared to its topical application after microneedling.

This study highlights the significant risk of vascular embolism associated with hyaluronic acid filler injections, emphasizing concerns about potential irreversible damage when fillers are injected in "unexplored" facial areas due to complex and variable facial anatomy.

This study examined the follicular unit density in the scalp and beard donor areas of Indian men undergoing hair restoration surgery, reporting mean densities of 78.2/cm² and 49.7/cm² respectively, and proposed guidelines for safe follicular unit extraction.

This article proposes enhancing the Norwood-Hamilton scale for assessing hair loss patterns but reports no new clinical results.

The authors suggest that during hair transplantation for hair loss, the parietal eminence area should be prioritized along with the mid-scalp to address future noticeable thinning, especially since this area often becomes more conspicuous over time.

In this pilot study, researchers found that fractional picosecond laser therapy may promote hair regrowth in men with mild-to-moderate androgenetic alopecia, with significant improvements in expert assessments and patient satisfaction observed over a four-month period, though further research is needed to confirm these findings.

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

This article describes a case of localized trichorrhexis nodosa in a patient with otherwise normal hair, highlighting the condition's response to trauma and diagnostic process but reporting no new clinical findings.

A new mutation in the TRPS1 gene caused Trichorhinophalangeal syndrome in a 17-year-old, highlighting the need for genetic testing.

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.

This study suggests that egfl6 expression in the pharyngeal pouches is not essential for craniofacial development in zebrafish.

This study discovered that TTR is expressed in the human placenta as early as 6 weeks gestation, with increased levels in the first trimester potentially facilitating thyroid hormone delivery to the fetus.

This study identifies specific molecular components involved in the intracellular trafficking of LGR5, revealing mechanisms that differ from typical GPCR recycling processes.

In this study, the researchers introduced a mutation in mice to mimic Olmsted syndrome and found that the mutation caused hair loss due to impaired keratinocyte differentiation and depletion of hair follicle stem cells.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.

In this study, researchers found that hair alterations such as frontal-occipital inversion in males and a high occipital hairline may aid in diagnosing the uncommon condition TRPS.

In this study, researchers used synchrotron X-ray imaging to examine rat vibrissa follicles, finding that despite variations in vibrissa length and follicle size, certain sensory structures remain consistent, suggesting specialized roles in sensory processing depending on the vibrissa type.

This case report highlights the discovery of a novel TRPS1 gene mutation in a 17-year-old with TRPS type I, underscoring the diagnostic importance of hair symptoms in congenital hair diseases.

This study found that mice with a disrupted TGFα gene display a curly whisker-coat phenotype, similar to waved-1 mice, suggesting TGFα's crucial role in skin architecture and hair development.

This case report describes a 7-year-old girl initially misdiagnosed with SMA syndrome, but later found to have a gastric trichobezoar via EGD, highlighting the diagnostic challenges in children with nonspecific symptoms.

Immune cells called Treg cells are essential for hair growth and regeneration.
