- Abstract: The safety and efficacy of Poly-L-lactic acid (PLLA) as an injectable facial volumizer for the treatment of lipoatrophy and facial rejuvenation has been widely proven. We experienced a remarkable case of deep-seated nodules on both the cheeks of 57-year-old female 18-months after administration of PLLA filler injection for cosmetic purpose and performed a skin biopsy. With hematoxylin and eosin stain, the nodule showed non-caseating granulomas consisting of histiocytes with central foreign bodies in the dermis. This case report represents the late-onset foreign body reaction due to PLLA facial injections.
