This study describes the case of a Filipino woman with virilisation, where a rare ovarian Leydig cell tumour was identified and removed, normalizing her testosterone levels.

This case report presents a rare instance of recurrent ACTH-independent Cushing’s syndrome due to PBMAH, coinciding with the development of a pheochromocytoma, highlighting the need for thorough reevaluation in similar recurring cases.

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 case study discussed a postmenopausal female with androgenic alopecia and hirsutism due to a Leydig cell tumor, suggesting the importance of further workup in women with severe hirsutism or androgenic alopecia.

Dermoscopy is useful for diagnosing and monitoring discoid lupus erythematosus by showing specific skin patterns.

This article highlights differences in childhood alopecia areata compared to adult cases but reports no new clinical findings.

This review examines the histopathologic features of four common types of noncicatricial alopecia and reports no new clinical results.

This review of 1360 scalp biopsy specimens revealed that 12.5% of cases involved multifactorial alopecia, highlighting the diagnostic complexity of multiple forms of alopecia present in single biopsies.

This study concluded that a polarized-light handheld dermatoscope attached to a digital camera is a practical and useful tool for diagnosing different types of alopecia.

This review discusses the classification and diagnosis of primary scalp alopecia, focusing on scarring and non-scarring types, and reports no new clinical results; it emphasizes simplified diagnostic pathways and tissue processing techniques.

This study found that clinically non-affected perilesional scalp in Japanese alopecia patients often showed microscopic abnormalities, which may help in assessing the spread of disease activities.

This study found that finasteride-induced androgen deficiency in an animal model resulted in tear deficiency and increased inflammatory cytokine expression in the lacrimal gland, potentially aiding in understanding dry eye pathogenesis.

This article evaluates reflectance confocal microscopy features of scalp melanoma but reports no new clinical results, suggesting further investigation is needed.

This study found that androgenetic alopecia was the most common cause of frontal hairline recession in Egyptian female patients, supporting the use of trichoscopy as a noninvasive diagnostic tool.

Advanced imaging techniques are crucial for accurately diagnosing Monilethrix, a rare hair disorder.

Histopathology is crucial for accurately diagnosing eruptive vellus hair cysts.

This study highlights the variation in clinical findings of traction alopecia and emphasizes that changes in hairstyles may prevent progression to scarring alopecia.

This study found that patients with autoimmune skin diseases showed a statistically significant occurrence of hearing disabilities, suggesting the need for audiological evaluations in these patients.

This study found no significant differences in age, sex, or histopathological characteristics for differentiating basal cell carcinoma from benign tumors of cutaneous appendages, complicating diagnosis.

This review discusses the histopathological diagnosis of scarring and non-scarring alopecias, emphasizing the importance of adequate tissue sampling and clinical information; it reports no new empirical results.

This study found that in Alopecia Areata, increased non-anagen terminal follicles and peribulbar lymphocytic infiltrate are consistent histological features, even in cases that have progressed to scarring.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

In this study of 20 patients with erosive pustular dermatosis of the scalp, using trichoscopy improved diagnosis, and treatments with high-potency steroids or topical tacrolimus effectively reduced inflammatory signs, suggesting these as first-line treatments.

This research retrospectively evaluated 92 skin specimens to propose histopathological criteria for diagnosing alopecia areata incognito, distinguishing it from telogen effluvium and androgenetic alopecia.

This review discusses histologic findings in alopecia and emphasizes the importance of understanding normal follicular anatomy and cycles in transverse sections, without reporting new results.

This study found that diffuse and pseudo-fringe sign patterns are common in Asian patients with frontal fibrosing alopecia, and that treatments combining antiandrogens or antimalarials with topical therapy are effective.

This review systematically analyzed literature to differentiate desmoplastic trichoepitheliomas from other cutaneous tumors based on clinical, histopathological, and immunohistochemical features but reports no new clinical results.

This case report describes a patient with Birt-Hogg-Dube syndrome exhibiting multiple fibrofolliculomas, acrochordons, and renal oncocytoma.

This review discusses the cosmetic and health implications of hirsutism and highlights its potential link to serious underlying disorders, but it presents no new clinical findings.

The research concluded that in men with androgenetic alopecia, dutasteride was more effective than finasteride at increasing hair count after 24 weeks, with similar side effect profiles.
