Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular proliferation that poses therapeutic challenges due to frequent recurrence and cosmetic concerns. We report a 40-year-old woman with nodular ALHE of the right ear, previously unresponsive to corticosteroid injections, successfully treated with intralesional radiofrequency (RF) using an insulated microneedle RF (MNRF) needle. The uniqueness of our case is the use of an innovative and cost-effective insulated needle assembly adapted from an MNRF probe. This modification was specifically designed to enhance precision while minimizing surrounding epidermal damage. This design improves durability and conductivity while reducing complications often seen with conventional probes. Six monthly sessions achieved marked lesion regression and excellent cosmetic outcome without recurrence at 6 months.
