Abstract
BACKGROUND: Cases of non-scarring alopecia after endovascular brain surgery have been reported, but dermoscopic findings of these lesions have rarely been published.
OBJECTIVE: To report the dermoscopic findings for alopecic skin lesions that developed after radiation exposure during angioembolization.
METHODS: Dermoscopic examination was used to evaluate alopecic skin lesions in 10 patients who presented with post-angioembolization alopecia.
RESULTS: The male to female ratio was 1:4, mean age 55.0 ± 12.3 years and mean duration to lesion development 3.4 ± 2.5 weeks. The rectangular-shaped lesions mostly occurred at the occiput and temple areas. Both yellow and black dots were the predominant dermoscopic findings in 60% (6/10) of patients, followed by short vellus hair (50%), peripilar sign (20%), broken hair (10%), coiled hair (10%) and white dots (10%).
CONCLUSIONS: Alopecic skin lesions induced by radiation exposure during angioembolization share characteristic dermoscopy findings with alopecia areata. They may be misdiagnosed if a precise history is not obtained.
