This article describes a 10-month-old female with congenital smooth muscle hamartoma, highlighting the importance of differential diagnosis in congenital skin lesions due to potential malignancy risks.

This study found a previously unreported ST14 gene mutation in a patient with ichthyosis-hypotrichosis syndrome, highlighting novel skin and hair characteristics and emphasizing the critical role of the Asp482 amino acid in matriptase activation.

This study found that erosive pustular dermatosis of the scalp is frequently misdiagnosed as squamous cell carcinoma, highlighting the need for careful differentiation to avoid unnecessary treatments.

This study found that erosive pustular dermatosis of the scalp is often misdiagnosed as squamous cell carcinoma, highlighting the importance of biopsy for accurate diagnosis.

This case series detailed three postmenopausal women with ovarian steroid cell tumors, highlighting that such tumors may present asymptomatically or with virilization, and found surgery effectively normalized androgen levels, with distinctive imaging features aiding diagnosis.

This study found that by using an automated system to analyze skin histology, 108 structural features were significantly affected by age, and it identified four new aging biomarkers and notable sex-based differences in skin aging.

Alopecia areata is a common autoimmune condition causing varying hair loss, diagnosed by specific patterns of inflammation around hair follicles, with several treatment options available.

This paper identifies challenges in diagnosing alopecia variants, emphasizing the importance of pathologists understanding hair follicle histology, biopsy types, and collaborating with dermatologists to improve diagnostic accuracy.

This study reports that some patients with androgenetic alopecia may also exhibit clinical and histological features of inflammation and fibrosis, similar to those found in lichen planopilaris.
