Artecoll granuloma: a rare adverse reaction induced by microimplant in the treatment of neck wrinkles.

BACKGROUND: Artecoll is now being widely used as an injectable aesthetic microimplant for the treatment of wrinkles because of its long-lasting cosmetic effects and the rarity of late complications, including foreign body granulomas. Recently, however, several cases of Artecoll-induced granulomas on the face have been reported, especially in patients receiving overly superficial or overly correcting implants. METHODS AND
RESULTS: A 50-year-old Korean woman who had been treated with Artecoll for the correction of the neck wrinkles presented 4 years later with an extensive Artecoll-induced foreign body granuloma along the injection sites in the neck. After three intralesional injections of triamcinolone acetonide, the lesions had almost disappeared.
CONCLUSION: To our knowledge, this case is the first report of an extensive Artecoll-induced granuloma on the neck. Our findings suggest that Artecoll not be used as implant material in thin and constantly movable skin, such as that of the neck.
