Objective

Study Design

Clinical and histopathologic data were obtained from 25 patients who developed orofacial nodules or swelling after dermal filler injections.

Results

All 25 patients were women aged 35 to78 years (median, 55 years). All had a history of injection of CHA (n聽= 13) or PLA (n聽= 12) to the lips, nasolabial area, or mental area. Two patients developed cutaneous nodules at the sites of injections; all others presented with intraoral nodules (labial/buccal or vestibular mucosa) distant from the site of injections, suggestive of filler migration. Five of 21 cases presented with pain. Histopathologically, CHA presented as a diffuse mass of mauve-gray or beige, nonrefractile spherules, and PLA as rice- or spindle-shaped, geometric, refractile bodies within circumscribed nodules.

Conclusions

Cutaneous injections of CHA and PLA fillers may induce granulomatous reactions presenting as intraoral nodules distant from the injection sites.
