This case report details an 80-year-old woman with circle hair potentially linked to acquired ichthyosis from multiple myeloma, where a prescribed topical treatment led to clinical improvement.

Polarizing light microscopy can easily and reliably diagnose congenital keratinizing disorders like Netherton syndrome.

This study described two cases of trichoblastomas in the tactile hair skin of aged house musk shrews, highlighting that their histological structure differs from that in humans and other animals.

This report describes four trichoblastoma cases rich in Merkel cells, suggesting these tumors may mimic fetal skin development where Merkel cells are numerous.

This study found no conclusive link between prolonged mibolerone treatment and perifollicular mineralization in toy poodles, suggesting it may instead be a senile change common in the breed.

In this case study, a 51-year-old Japanese man was diagnosed with desmoplastic trichoepithelioma after histological examination of surgically excised facial plaques.

This case report documents the second known instance of a salivary gland choristoma on the chest wall of a newborn, highlighting its benign nature and the importance of accurate diagnosis.

In this case report, a newborn with Conradi-Hünermann-Happle syndrome was diagnosed through early skin biopsy, which revealed unique histopathological features, including dystrophic calcifications, confirming a pathogenic variant in the EBP gene.

In this study, researchers found that skin pigmentation alterations in a mouse model of Carney complex may be caused by specific dermal fibroblasts promoting melanogenic signaling.

This case report describes a black male newborn who developed bullae that healed with hypopigmentation, linked to collagenolysis and RER vacuoles potentially containing proteolytic enzymes.

This case report describes two instances of naevoid bundle hair on the scalp, where multiple hairs group from separate follicles into a single sheath and show abnormal reactivity to keratin antibodies.

This study found that high levels of μ-crystallin in skeletal muscle are associated with greater fat metabolism and a shift in gene expression towards slower muscle function.

In this study, electron microscopy of follicular mucinosis showed severe cytoplasmic degeneration in hair follicles, with myelin figures and onion-like lamellar structures, but no indications of mucin release through degeneration or degradation were found.

This case study reports a patient with Rothmund-Thomson type congenital poikiloderma, showing primarily skin changes and hair loss, along with slightly elevated lysine and cystine levels in urine.

This case report describes a 44-year-old patient with late-onset partial lipodystrophy, mental retardation, epilepsy, ichthyosis, and glomerulonephritis, linked to a 10 Mb duplication of chromosome region 5q31.3-5q32.1.

In this case report, the authors observed that understanding the cytological features of trichilemmal carcinoma is crucial for accurate FNAC diagnosis of its metastases in head and neck regions.

This case study identified the condition as Monilethrix in a 17-year-old female, characterized by a beaded hair appearance and linked to a genetic cause.

This study found that nevoid basal cell carcinomas originate in the epidermis and the upper part of the hair follicle, showing similarities to nonnevoid basal cell carcinomas.

This study reports a rare case of polyorchidism in a 96-year-old male cadaver, suggesting a new classification based on anatomical and histological findings to aid in accurate diagnosis.

This case report describes a 10-year-old girl with monilethrix, detailing hereditary autosomal dominant traits and distinctive nodular hair shaft abnormalities observed in her family through clinical examination and microscopic analysis.

This study reports the first known case of multiple type nevus lipomatosus cutaneous superficialis in a 10-month-old girl, with the unique feature of perifollicular fibrosis.

This report is the first to associate Cronkhite-Canada syndrome with multiple myeloma, describing regenerative pseudopolyps in a 58-year-old woman rather than true adenomatous polyps.

This article reviews the identification and characterization of soluble proteins in horny tissues such as calluses and psoriatic scales, but reports no new clinical results.

This study found that cupric chloride treatment may partially correct delayed maturation and abnormal arborization of Purkinje cells in the cerebellum of hemizygous brindled mice, a model for Kinky hair disease.

This report describes two patients with ichthyosis linearis circumflexa exhibiting symptoms resembling Netherton's disease, noting multiple hair shaft defects and discussing a possible connection to aminoaciduria.

This study observed that the keratinization pattern of trichilemmal cysts in two Japanese women may originate from the proliferation of the outer root sheath in the follicular isthmus of anagen hairs.

This study reports that 14 of 19 patients with erythema nodosum leprosum had C3 deposits in vessel walls when examined using direct immunofluorescence.

New mutations in hair keratin genes can change hair structure and cause monilethrix, with nail issues more common in certain gene mutations.

This manuscript reports on the first case of perforating necrobiosis lipoidica in Colombia, marking the 19th documented case worldwide.

This study found that Naked trait mice exhibit a decrease in certain low-molecular-weight proteins in their hair, which contain high levels of glycine and tyrosine, compared to normal mice.
