BACKGROUND: In parallel with the increase in requests for filler injections, reported complications (immediate or delayed and transient or permanent) increased too.

CASE REPORT: In the presented case report, a patient reported a delayed complication of filler injection. The complaints of the patient and the objective evaluation revealed the presence of multiple lip nodules, that were painful both spontaneously and at the touch, after 10 years from a lip filler injection. The surgical excision of the neoformations permitted the complete healing of the lesions. The histological analysis showed a not specific pattern, showing a material encapsulated by a tissue reaction, confirming that the possible cause of the multiple injuries could be attributable to the injection received years earlier.

CONCLUSIONS: The professional who intends to perform filler injections needs a complete training process, both from a theoretical and practical point of view. Also, the patients must be informed of the possible risks associated with each product.
