This review examines recent literature on isotretinoin's teratogenic effects in both fertile females and males, analyzing its role in causing congenital malformations but provides no new clinical results.

This study found that ectopic expression of Whn in transgenic mice caused impaired differentiation in epidermis and hair follicles, with hair growth defects and severe urinary tract issues leading to hydronephrosis.

In this study, researchers observed that the sebaceous gland niche in mice allows for Wnt-induced hair follicle differentiation, unlike the non-permissive bulge.

This study reports that hair follicles can mobilize ectopic progenitors for regeneration to repair damage from ionizing radiation. Augmenting WNT signaling enhanced this regenerative process and prevented radiation- and chemotherapy-induced hair loss, highlighting a potential approach to manage alopecia during cancer treatment.

This review examines the potential role of odorant receptors in human skin cells responding to flavor compounds and their implications for skin health and disease, without providing new clinical results.

This study found that ectopic expression of FGF5s in transgenic Chinese Merino sheep increased wool length and greasy fleece weight compared to non-transgenic controls.

This case report describes an adult female with congenital adrenal hyperplasia who developed secondary amenorrhea and hair loss due to androgen overproduction from ovarian adrenal rests, detectable only after pelvic venous sampling, and normalizing after unilateral oophorectomy.

This case report documents the first known instance of an ectopic sebaceous gland and duct within a hair follicle in a 21-year-old male with persistent acneiform eruption.

This study suggests that Rushton’s hyaline bodies form through both epithelial changes leading to hair keratin production and hemorrhage supplying erythrocytic substances, resolving previous debates about their origin.

This case study reports an unusual occurrence of hair growth on the glans penis of a healthy 24-year-old man, which required surgical excision but recurred at a different site.

This study found that whisker follicle stem cells transplanted to injured spinal cords in mice contributed to healing and unexpectedly grew hair at the injury site.

This article reviews the occurrence of ectopic sebaceous glands in hair follicle matrix during hair embryogenesis and reports no new clinical results, indicating unknown pathogenesis and clinical implications.

This case report describes a 63-year-old woman with hyperandrogenism due to an ectopic adrenal gland adenoma on the ovaries, successfully treated with bilateral salpingo-oophorectomy.

In this study, a case of a 20-year-old woman revealed ectopic acanthosis nigricans at a post-syndactyly-release surgical site, suggesting this rare condition could result from epidermal–dermal mismatch and altered growth factor signaling in grafted skin, without indicating any metabolic or malignancy concerns.

This report describes a rare case of ectopic adrenocorticotropic hormone syndrome caused by a pheochromocytoma that unusually co-expresses both ACTH and corticotropin-releasing hormone.

A specific hair protein variant increases the spread of breast cancer and is linked to worse survival rates.

This research reports that after genotoxic stress from ionizing radiation or chemotherapy, hair follicles can utilize progenitor cells from transit-amplifying compartments, not quiescent stem cells, for repair, suggesting a potential therapeutic approach to prevent therapy-induced hair loss by activating these progenitors.

This study suggests that targeting the activation of transit-amplifying cell-derived progenitor cells may help prevent hair loss from chemotherapy and radiotherapy by promoting hair follicle regeneration.

This review discusses the diverse functions and therapeutic potential of ectopic olfactory receptors throughout the body, emphasizing their roles in various cellular processes and potential in cancer detection and therapy, but reports no new clinical results.

This case report describes a 34-year-old woman with pituitary stalk interruption syndrome, highlighting the need for long-term follow-up due to potential progression from isolated hormonal deficiencies to pan-hypopituitarism.

In this case study, the use of somatostatin analogues was effective in localizing and confirming a neuroendocrine lung tumor as the source of ectopic ACTH syndrome, leading to marked clinical improvement in a patient unable to undergo surgery.

In this study, transplanted whisker follicles from ND-GFP mice aided spinal cord repair in injured mice, and surprisingly, also grew long hair shafts at the site of transplantation.

This study found that misexpression of Hoxc8 in mice led to ectopic mammary development and suggests Hox genes may play crucial roles in the regional specification and initiation of cutaneous accessory organs.

This case report highlights the importance of thorough examination in detecting ectopic thyroid glands in patients with borderline congenital hypothyroidism identified during newborn screening, as early intervention can prevent future complications and improve outcomes.

This case report describes a patient with ectopic Cushing's syndrome who experienced fatal complications from COVID-19, highlighting the challenges in managing such patients due to immune response alterations from endogenous hypercortisolemia.

This study suggests that dsRNA may enhance KRT9 expression in palm and sole skin through β-catenin signaling, potentially linking mechanical damage to specific skin features and certain skin conditions.

The Trichodysplasia spinulosa virus protein can cause abnormal hair growth in mice.

In this study, sandalore was found to activate OR2AT4, which inhibits senescent cell traits and restores proliferation in human keratinocytes, suggesting potential anti-aging applications.

This study identified a 505-bp indel variant in the FGF5 gene associated with cashmere growth in goats, which may serve as a molecular marker in cashmere goat breeding programs.

This study identifies a strong association between a 505-bp indel mutation in the FGF5 gene and cashmere growth in goats, suggesting potential use as a genetic marker in breeding programs.
