Lower eyelid xanthelasma following hyaluronic acid filler injections to the tear troughs.

INTRODUCTION

Adverse effects from dermal fillers are uncommon. We report a case of filler-induced xanthelasma at the bilateral infraorbital region in a 43-year-old woman after multiple injections of hyaluronic acid to correct tear trough depression.

MATERIAL AND

METHODS

We report a case of a 43-year-old woman with a chief complaint of skin discoloration of the bilateral lower eyelids. Her history was significant for ten sessions of hyaluronic acid filler for tear trough deformity between December 2008 and May 2016. On clinical examination, she exhibited thin, soft, and yellow papules to her lower medial infraorbital hollows. A punch biopsy showed foamy histiocytes with a background of hypervascularization and focal extracellular lipid in the superficial dermis, consistent with xanthelasma.

RESULTS

Xanthelasma was treated with multiple passes of Er:YAG laser (Sciton Contour TRL) with a 4 mm spot size, fluence 7.5 J/cm2, and ablate/coagulate 50/50 at 6 Hz until clearance occurred. The perilesional skin was treated with 1-2 passes, fluence 7.5 J/cm2, ablate/coagulate 50/0 to blend in the cosmetic unit. Six-month follow-up showed notable improvement of all lesions.

DISCUSSION: There is a paucity of treatments described for filler-induced xanthelasma reaction. While broad conclusions cannot be drawn from one case, our experience indicates that complete resolution can be achieved with Er:YAG ablation. We hypothesize that this laser is an optimal treatment, as it can vaporize the lipid contents while minimizing adverse effects, such as scars and hyperpigmentation.
