Paraffinoma of lips and oral mucosa: Case report and brief review of the literature

Facial lipogranulomas due to self-injection of vitamin A oil

Lipogranulomas represent foreign body reactions to exogenous lipid or oil-like substances introduced into the skin. These lesions characteristically have round-to-ovoid, vacuole-like cavities of varying sizes in the dermis, which results in a Swiss cheese-like appearance. We present the case of a 51-year-old Hispanic woman with an onset of painful, swollen, subcutaneous nodules on the face, most prominently on the right lower lip and both cheeks, after multiple self-injections of vitamin A oil. Histopathology test results of the lower lip showed a superficial-to-deep, nodular and interstitial, polymorphous inflammatory infiltrate of predominantly histiocytes with necrobiotic-type granulomatous changes, lymphocytes, and plasma cells. The cheek revealed deep dermal and subcutaneous small collections of foamy/vacuolated histiocytes, without significant numbers of other inflammatory cells. Given the patient’s history of injecting oil extracted from vitamin A capsules into her skin, the light microscopic features are consistent with lipogranulomatous changes that are secondary to a local injection of foreign material. Clinicians and pathologists should be aware of the granulomatous immune reaction generated by the injection of unregulated products into the face and other areas of the body.

Oral foreign body granuloma to soft tissue fillers. Report of two cases and review of the literature

The increasing demand for cosmetic procedures in the orofacial area nowadays, results in a growing number of complications attributable to soft tissue fillers, including the development of foreign body granuloma. The purpose of this study is to present two additional cases of oral foreign body granulomas caused by liquid silicone and hyaluronic acid respectively and review the pertinent literature regarding the demographics, the clinical appearance, the histopathology and the treatment of these lesions.

Key words:Oral foreign body granuloma, hyaluronic acid, silicone, soft tissue filler.

Atypical Facial Filler Granuloma: Comparative Histologic Analysis with Paraffinoma

Dermal fillers are generally accepted as safe and well-tolerable cosmetic tools. However, adverse reactions have been reported in the literature. Here, we present a case of atypical facial filler granuloma and compare its histologic features with those of the classic paraffinoma.
