A 45-year-old female noticed a pruritic erythematous firm pea sized nodule on the left earlobe about 18 years prior to uisiting our clinic. The lesion has increased in size gradually and involved the whole earlobe. On March 1988, the earlobe became enlarged with extreme pruritus, and showed a tendency of easy bleeding by scratch. The skin lesions consisted of multiple pea to bean sized, shiny dusky red colored, moderate firm nodules or tumors with edema on the left. ear helix, antehelix, external auditoy meatus, and retroauricular fold. The histopathologic studies revealed vascular proliferation, presence of histiocyt.oid endothelial cells, and prominent inflammatory infiltration including large numtaer of eosinophils with fibrosis in the dermis. Hematological studies revealed eosinophilia(9%). Excision of several nodules and intralesional injection of trinmcinolon acetonide did not show complete favorable effect and treatment with carbon dioxide laser was attempted. With the patient under local anesthesia with 2% lidocaine, the lesion were treated with three t,o four passes at 25,100 second intervals with ieradiance 5W(cm. The pro- cedure was repeated until no abnormal findings could be seen in the treatment zone. Treatment with carbon dioxide Iaser on the patient obtained a satisfactory result.
