In recent years, dermal filler substances containing polymer particle suspensions such as Bioplastique, Artecoll, and Dermalive are the most commonly used materials. These microimplants are permanent, non-biodegradable, and generally well tolerated, although various adverse reactions are still possible. We describe here a patient with facial granulomas secondary to Dermalive injections for correction of naso-labial folds and wrinkles. The particular shape of the injected particles allows for correct identification of the implanted material. Therefore, histopathologic examination is the best means to obtain the correct diagnosis of foreign body granuloma and to identify the type of filler particles. We discuss the histopathologic differential diagnosis among the granulomas secondary to the most commonly used aesthetic permanent filler materials. © 2006 Lippincott Williams & Wilkins, Inc.
