Hedgehog signaling is crucial for hair development, cadherins affect cell adhesion, neutrophils play a role in skin lesions, and BP230 autoantibodies impact skin stability.

This case report describes a rare instance of nevus comedonicus with a multi-dermatomal unilateral pattern along the lines of Blaschko, treated unsuccessfully with topical tretinoin and oral retinoids.

This study found that the combination of cyproterone acetate and ethinyl estradiol improved hirsutism and acne in women, with SH 8.1041 showing significant results and both treatments being generally well-tolerated.

In this study, researchers found that basal cell carcinomas with common Hedgehog signaling mutations may require additional mutations to hyperactivate downstream signaling and progress beyond dormancy.

This report details a rare case of late-onset, bilateral nevus comedonicus on the eyelids in a 79-year-old man, discussing its clinical presentation and histopathologic features without presenting new research findings.

Etanercept is safe and may help improve hidradenitis suppurativa, but more research is needed.

This review summarizes recent genetic research on hidradenitis suppurativa, highlighting potential therapeutic targets and genetic mutations, but reports no new clinical findings.

This study found that AA may have a protective role in the progression of both HBDC and CRC, suggesting potential new research avenues for treatments of these conditions.

In this study, researchers described hyperandrogenism as a condition resulting from excessive androgen production, which can lead to symptoms like acne, hirsutism, and hair loss, particularly relevant for dermatological evaluation and management in adult females.

This report describes a case where severe hair loss occurred as an early manifestation of Hodgkin disease, with the literature suggesting it might result from follicle destruction or toxic effects.

This chapter reviews the causes, diagnosis, and treatment of hirsutism and related androgen excess conditions in women, presenting no novel clinical findings.

A woman developed lupus after taking hydroxyurea for two years.

This study reports a new association of follicular mucinosis occurring in a patient with Sézary syndrome.

This study reports that a novel frameshift mutation in the HTRA1 gene in a CARASIL pedigree led to reduced HTRA1 protein and increased TGF-β1 expression, potentially causing severe CARASIL and peripheral small arterial disease.

This case report describes a 32-year-old man who developed SCC of the common bile duct a year after receiving treatment for a malignant proliferating trichilemmal tumour on the scalp.

This study found no significant relationship between hormone levels and sexual function in young women with hirsutism compared to a control group.

In this study, patients with telogen effluvium had significantly lower levels of haemoglobin, hematocrit, and serum ferritin compared to healthy controls.

This review discusses the clinical features, genetics, and treatment of 21-hydroxylase deficiency, a common type of congenital adrenal hyperplasia, and reports no new research findings.

Three related Persian cats have a rare, likely hereditary skin condition causing hair loss and poor coat quality, with limited treatment options.

This paper discusses anagen effluvium, a reversible non-scarring hair loss often triggered by certain chemotherapy drugs, but presents no new clinical results.

This study reports a case of frontal fibrosing alopecia associated with hepatitis C treatment involving interferon and ribavirin.

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 case report describes a patient with diffuse large B cell lymphoma who experienced temporary Beau’s lines and onycholysis while undergoing R-CHOP chemotherapy, which resolved two months after treatment ended.

This review discusses various theories of the causes and management strategies for hidradenitis suppurativa, reporting no new experimental results, with a focus on the immune basis of the disease.

In this study of women with hirsutism or androgenic alopecia, diverse underlying endocrine disorders including polycystic ovaries and various enzyme deficiencies were detected, often associated with elevated testosterone levels.

This case report describes a 43-year-old woman with achalasia, pangastritis, and hyperthyroidism, highlighting the rare association between achalasia and autoimmune conditions like hyperthyroidism.

This review discusses idiopathic hirsutism, potential underlying mechanisms, and various therapeutic approaches without providing new clinical results, and emphasizes the need for further research on well-defined patient groups.
