Effect of microscopic XL-radiofrequency ablation on head-facial papulosa nigra and lichenoid seborrheic keratosis

Objective To observe the effect of microscopic XL-radiofrequency ablation on head-facial papulosa nigra and lichenoid seborrheic keratosis（LSK）.Methods Sixty-three patients with head-facial papulosa nigra and LSK（32 males,31 females） at the age of 35-81 years who visited our outpatient department from April 2008 to October 2011 were included in this study.The course of their disease was 6 months-40 years.The number of lesions was 274 with a minimal size of 4 mm×3 mm and a maximal size of 30 mm×25 mm.The diameter of 42 lesions was 10 mm.Five lesions were located in the vertex and temple while the rest were located on the face.The lesions were treated once with microscopic XL-radiofrequency ablation.The patients were followed up for 6 months-2 years.Results Of the 274 lesions in 63 patients,268 were cured with an excellent effect for 6 lesions and mild depigmentation in 1 lesion.No scar formation was found.Conclusion Microscopic XL-radiofrequency ablation shows a high curative rate for papulosa nigra and LSK with no scar formation.
