Abstract

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.

INTRODUCTION

Soft tissue augmentation has become one of the most popular procedures for rejuvenation and aesthetic improvement. This increase in the use of dermal fillers has led to numerous reports on side effects, including foreign body reactions. Foreign body granulomatous reactions following filler injections have different histologic features compared to those following other injectable materials. In this study, we present a case of a granulomatous reaction induced by a filler material with histologic analysis in comparison with paraffinoma, along with a literature review of granulomatous reactions after facial cosmetic filler injections.

CASE REPORT

We encountered a 58-year-old woman who received a cosmetic local injection of unknown agents in the nasolabial folds 8 years ago. Two months prior to visiting our clinic, the patient noticed soft-tissue irregularities along the nasolabial fold, which began to increase in size, accompanied by mild local inflammation signs, and migrated into the marionette lines (Fig. 1). Magnetic resonance imaging (MRI) revealed granulomatous tissue occupying the subcutaneous layer in both corners of the mouth (Fig. 2).

Complying with the patient's wishes, the lesions were resected through direct cutaneous approach (Fig. 3). The surgical specimen were sent for histologic analysis, which revealed granulomatous reactions with multinucleated giant cells surrounding multiple foreign materials (Fig. 4). In contrast, histologic findings of paraffinoma, according to the literature review, show giant cells and variable-sized empty vacuoles and cysts (Fig. 5).

DISCUSSION

Complications associated with filler injection may be immediate, early (within days), or delayed (after weeks to years). Immediate complications include injection site reactions such as erythema, edema, pain, and bruising. Early complications include infection (mostly staphylococcal or streptococcal), hypersensitivity reaction, skin discoloration, vascular occlusion, and contour irregularities [1].

Delayed complications include infections (mostly mycobacterial), foreign body granulomatous reaction, migration of implanted material, persistent discoloration, and scarring [2]. Lemperle et al. [34] divided foreign body granulomas into three types based on clinical features: cystic granulomas, edematous granulomas, and sclerosing granulomas. Usually, the type of foreign body granulomas primarily depends on the type of filler used, but this is a pattern and not an absolute correlation. Granulomatous foreign body reactions appear after a variable period, between 5 months to 15 years [5].

In our patient, clinical and histological findings suggest the granuloma to be of sclerosing type. Sclerosing granulomas can occur after subdermal implantations of all types of particulate material (e.g., Artecoll, New-Fill/Sculptra, Dermalive, Radiesse) as well as fluid implants (e.g., silicone 350, Aquamid).

Silicone infiltrations have been used in medical practice for years, in both solid and liquid forms, exclusively or in combination with other products. Silicone was initially believed to be innocuous to body tissues, in the same manner as hyaluronic acid, collagen, or polylactic acid. However, evidence of adverse effects of these materials surfaced in the form of foreign body granulomas. In contrast, paraffinoma is characterized by a granulomatous inflammation of the skin due to the introduction of mineral oils of which the paraffin is usually the main component. Paraffin is a mixture of high-molecular-weight hydrocarbons with a colorless-to-white color. Accidental or intentional subcutaneous infiltration has been reported to cause foreign body reactions develop and may even cause ulceration in some cases [6].

Histologically, paraffinoma is a granulomatous foreign body reaction that results from the interstitial application of oily substances [7]. So-called oil cysts with empty centers and rims of foamy or multinucleated macrophages represent the typical histologic finding in paraffinoma.

It is difficult to differentiate paraffinoma from siliconoma in H&E stain because the Swiss cheese and onion-skin pattern appear in both diseases. Special stainings such as oil red O or Sudan IV stain can demonstrate the presence of oil in the cysts of variable size [8].

Generally, patients with foreign body granulomas are asymptomatic. Common reasons for consultation is the presence of subcutaneous nodules, swelling, and deformation. Many patients are unable to recall exactly the type of filler material injected because of the long delay in granuloma formation and/or the lack of adequate information at the time of injection (infiltrations for many years being performed in clandestine non-healthcare settings).

In the treatment of foreign body granulomas, it is necessary to consider intralesional steroid injection as a primary treatment option. Most foreign body granulomas can be treated successfully with the steroid injections alone. Furthermore, a differential diagnosis should be performed to distinguish granulomas from nodules, and the treatment should be tailored according to the type and cause of granuloma.

Surgical resection have been carried out in extreme cases of granulomas, especially for paraffinomas and siliconomas, although such a treatment is considered highly aggressive and does not guarantee full removal of the widely disseminated filler material, which may be impossible to separate from normal facial tissues [9].

Injecting fillers into the subdermal layer is considered safer than injecting into the intradermal layer in preventing granulomas because the dermis is by far the organ most sensitive and most susceptible to immunologic reactions [3]. Also, it is recommended to not inject large amount of fillers in a single area.

Furthermore, we as physicians should be aware that all filler materials have potential for side effects and that the risk can be diminished but not completely eliminated. Also, we should give a detailed explanation of risks involved to patients beforehand.
