[Macrolane®: A severe case of calf cellulitis after modeling injection].

In recent years, the market for resorbable injectables has been steadily expanding. The European Community's seal of approval (CE) is a sufficient guaranty to get them distributed. These injectables do not require official approval because they are considered to be "implantable medical devices" and not medicines. Macrolane(®)is a hyaluronic acid in gel form (NASHA [non-animal stabilized hyaluronic acid]) and has been on the French market since 2007. It can be injected into all areas except the face. It is highly cross-linked which, while slowing its absorption into the body, can also leave long-lasting residues. We report the first case of cellulitis after injection into the calf by a practitioner in his office.
