This review discusses the etiology, pathophysiology, trichoscopic characteristics, differential diagnoses, and treatment options for scalp seborrheic dermatitis, without providing new clinical findings.

This study observed that trichoscopy of long-lasting lesions in a chronic stage revealed specific features such as absence of follicular openings, cicatricial patches, and thick arborizing vessels.

Dermatoscopy helps track scar changes and guide treatment.

In this case report, a 74-year-old woman initially diagnosed with androgenetic alopecia was later found to have secondary alopecia neoplastica due to morpheaform basal cell carcinoma of the scalp, illustrating the importance of recognizing subtle clinical features to prevent delayed treatment and potential local destruction.

In this retrospective study, researchers from the University of Bologna observed that trichoscopy can aid in diagnosing allergic scalp contact dermatitis, with key findings including common trichoscopic patterns of erythema, white scales, arborizing vessels, and simple red loops in 12 patients diagnosed with the condition.
