PURPOSE: Injectable implants used for soft-tissue augmentation may lead to a granulomatous foreign-body reaction. The aim of this report is to present 7 new cases of foreign-body granulomas involving the oral and perioral tissues, after injection of biomaterials to achieve soft-tissue augmentation. In addition, the clinical and epidemiological profile of this condition is summarized, based on a review of the English-language literature of all previously described cases.
PATIENTS AND METHODS: We report on 7 new cases of granulomatous foreign-body reaction involving the oral and perioral tissues after the injection of biomaterials. A comprehensive literature review is also presented.
RESULTS: The literature search revealed 49 cases of this condition affecting the oral and perioral tissues. Our 7 patients were female, with a mean age of 52.8 years (range, 34 to 70 years). The lower lip was affected in 4 cases, 1 case was located in the upper lip, 1 case in the buccal mucosa, while 1 case involved 2 different sites (upper lip and buccal mucosa). Histopathologic examination revealed numerous cells with clear, often multiple, cytoplasmic vacuoles, bearing a resemblance to lipoblasts. Immunohistochemistry revealed diffuse positivity for the histiocytic marker CD68.
CONCLUSIONS: The diagnosis of granulomatous foreign-body reactions may be challenging because of their microscopic resemblance to liposarcoma, and because of the occasional reluctance of patients to report the previously performed esthetic procedure. A clinical history, histopathologic examination, and immunohistochemical analysis (as needed) are essential in achieving an accurate diagnosis.
