Treatment Options Foot Gottfried Lemperle, M.D., Summary: Foreign body granulomas occur at certain rates with all injectable Ph.D. dermal fillers. They have to be distinguished from early implant nodules, which Nelly Gauthier-Hazan, M.D. usually appear 2 to 4 weeks after injection. In general, foreign body granulomas San Diego, Calif.; and Paris, France appear after a latent period of several months at all injected sites at the same time. If diagnosed early and treated correctly, they can be diminished within a few weeks. The treatment of choice of this hyperactive granulation tissue is the intralesional injection of corticosteroid crystals (triamcinolone, betamethasone, or prednisolone), which may be repeated in 4-week cycles until the right dose is found. To lower the risk of skin atrophy, corticosteroids can be combined with antimitotic drugs such as 5-fluorouracil and pulsed lasers. Because foreign body granulomas grow fingerlike into the surrounding tissue, surgical excision should be the last option. Surgery or drainage is indicated to treat normal lumps and cystic foreign body granulomas with little tissue ingrowth. In most patients, a foreign body granuloma is a single event during a lifetime, often triggered by a systemic bacterial infection. (Plast. Reconstr.
