This case series observed the diagnostic challenges of secondary syphilis, highlighting diverse presentations such as rashes and systemic symptoms that can mimic other conditions, underscoring the importance of dermatological review, serological testing, and interdisciplinary care for effective treatment and management.

In this report, two cases of melanocytic matricoma, a rare benign hair follicle lesion that mimics melanoma and basal cell carcinoma, were described and successfully treated with complete surgical excision. Histological analysis was crucial for differentiation from similar malignant lesions.

In this prospective observational study of 96 dermatomyositis patients, 47 showed scalp involvement, with significant symptoms like scalp inflammation, itching, and hair loss linked to myositis-specific antibodies. The study highlighted unique dermatopathological features in the scalp and emphasized the considerable morbidity caused by scalp dermatomyositis.

This study found that prostaglandin receptors are widely expressed in hair follicles, suggesting a complex network of prostanoid pathways involved in hair growth control.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.
