Dermabrasion for lichen amyloidosus. Report of a long-term study.

Seven patients with lichen amyloidosus were treated with dermabrasion during the last seven years. All patients have had follow-up examinations for at least five years (one patient for seven years). The main symptom, itching, disappeared in all cases, and the clinical results were satisfactory, except for mild hyperpigmentary and depigmentary changes in the treated areas.
