In this case report, researchers diagnosed a 12-year-old girl with a nevus sebaceus of Jadassohn, characterized by a yellowish-pink plaque on the scalp and a genetic variant, following previous misdiagnosis as alopecia areata.

This case report details the first pediatric occurrence of naevus trichilemmocysticus, a newly defined type of organoid naevus.

This article discusses various types of epidermal nevi and associated syndromes but presents no new research findings.

This case report describes a male child with alopecia areata and renal dysgenesis, highlighting a possible coincidental association that may require future genetic investigation.

This review reports two new cases of porokeratotic eccrine and hair follicle nevus and analyzes all known cases in the Spanish and English literature, suggesting a link to a GJB2 gene mutation.

In this report, a 1-year-old boy with congenital atrichia with papular lesions was found to have a complete absence of scalp and body hair and keratin-filled cysts due to a mutation in the hairless gene.

This manuscript describes two case reports of preterm newborns with a rare homozygous mutation in the epidermal growth factor receptor, leading to severe health issues and early mortality despite supportive care.

In this study, transgenic mice expressing Msx-2 developed flaky skin with hyperproliferation and misalignment in epidermal cells, suggesting Msx-2 plays a role in skin and appendage growth control.

This article reviews the case of a 2-year-old boy with rhombencephalosynapsis and considers its potential links to Gomez–López-Hernández syndrome, suggesting further research into its genetic causes; no new clinical results are reported.

This study found that in superficial angiomyxomas, S100A4-positive mesenchymal niches may induce non-neoplastic adnexal epithelial growth, and highlighted evidence of mesenchymal-to-epithelial transition in eccrine duct branching, especially in Carney's complex cases.

This article reviews congenital and developmental skin conditions in foals and reports no new clinical results; it notes that these conditions can be influenced by genetic and environmental factors.

This report describes a 3-year-old boy with a potential new neurocutaneous syndrome characterized by unilateral alopecia, ipsilateral hemimegalencephaly, and intractable seizures.

This report describes a rare case of a three-day-old male with ichthyosis hystrix type of epidermal nevus, featuring specific skin and hair symptoms but no nail or skeletal abnormalities.

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.

This study suggests that exogenous retinoic acid can alter the morphogenesis pathway of developing skin appendages when applied during the placodal stage, leading to changes like feather formation in atypical regions of chick embryos.

This case report highlights a 21-year-old man with severe nodulocystic acne resistant to conventional treatments, who showed moderate improvement with isotretinoin, and discusses its potential link to congenital digital abnormalities and Apert syndrome.

This case study describes a 9-year-old girl with a homozygous EGFR gene mutation, presenting with tubulopathy and chronic dermatitis, whose ongoing symptoms and management offer insights into this rare genetic condition.

This study observed unique ultrastructural changes in a 4-year-old girl with pili trianguli et canaliculi that may affect hair shaft surface characteristics due to inner root sheath alterations.

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 investigated the mechanism responsible for pili torti formation in Björnstad syndrome using a transmission electron microscope, but did not establish a definitive explanation.

This case report details atrichia with papular lesions in a 4-year-old girl, highlighting specific histological findings on her scalp and other affected areas.

Patients with GATA2 deficiency show early skin symptoms that help diagnose the condition.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

This study suggests that congenital atrichia with papular lesions may be more common than previously thought and proposes diagnostic criteria including the observation of hypopigmented whitish streaks on the scalp.

In this study, forced expression of the transcription factor cDermo-1 in chicken dermis led to the formation of ectopic feather buds and enhanced feather growth, demonstrating its role in initiating skin appendage development.

Buschke-Ollendorff syndrome is a rare genetic disorder causing skin and bone changes, with some cases also showing ADHD or developmental delays.

This article reviews how anatomical differences in skin arise and persist, and suggests the underlying molecular positional code is more complex than apparent, but reports no new research findings.
