A technique for periorbital syringomas: intralesional radiofrequency ablation

Radiofrequency ablation micro-dissecting of eyelid nevus with XL-RFA device under operating microscope

AIM

To study the effect of an innovative micro-dissection procedure by radiofrequency ablation (MRA) in removing eyelid nevus.

METHODS

Fifty-six consecutive outpatients with eyelid nevus were treated with MRA using a monopolar device. The effect of MRA was determined after following-up for 6mo to 5y.

RESULTS

Fifty-two cases (52 eyes, 92.9%) were cured once, and 4 cases (4 eyes, 7.1%) received second treatment for small residual. All cases healed well after surgery, with no pigmentation, no scars, no loss of eyelashes, no deformation of eyelid margin. There was no visual impairment after healing.

CONCLUSION

MRA of eyelid nevus using the XL-RFA device is highly efficient without significant complications.

Angiolymphoid hyperplasia of external ear treated with intralesional radiofrequency ablation

A 21-year-old woman presented with multiple erythematous to skin-coloured dome-shaped firm papules and plaques over the right ear concha and external auditory canal for 1 year. It was associated with occasional itching and bleeding. Her main concern was cosmetic disfigurement. Biopsy showed presence of multiple proliferating blood vessels lined by plump epithelioid endothelial cells surrounded by dense infiltrate of lymphocytes, histiocytes and eosinophils. Other routine investigations were within normal limits. A diagnosis of angiolymphoid hyperplasia with eosinophilia was made. A single sitting of intralesional radiofrequency ablation (Vesalius, coagulation mode; fanning technique) using 18-G intravenous cannula was done. This led to almost complete resolution with no recurrence at 3 months follow-up. There was no evidence of scarring or depigmentation.
