Foreign Body Granuloma Due to Matridex Injection for Cosmetic Purposes

Cerebral Embolism as a Result of Facial Filler Injections: A Literature Review

Background

With the growth in the popularity of facial filler injections, increased numbers of severe adverse events, such as cerebral embolism, have been reported.

Objectives

The aim of this article was to summarize the clinical manifestations and proposed mechanisms of filler-induced cerebral embolism (FICE).

Methods

A literature review was performed with the search keywords “filler injection,” “hyaluronic acid,” “fat graft,” “cerebral infarction,” “cerebral embolism,” “stroke,” “cerebrovascular infarction,” “disorders of consciousness,” and “hemiplegia.”

Results

Among the 43 cases of FICE enrolled from 35 articles, 37 patients were female, and 6 were male. Twenty-nine of these patients had received fat grafting, and 12 hyaluronic acid injection. Most FICE patients had been injected in the glabella, followed by the temporal, forehead, and nasal areas. Among 30 patients injected under local anesthesia, 43.33% presented with neurologic symptoms during the procedure. The main symptoms were consciousness disorders and hemiplegia. Most of the embolization sites were in the middle cerebral artery, followed by frontal lobe infarction and anterior cerebral artery infarction. Three patients developed cerebral hemorrhage after embolism. Twenty-six patients presented with newly acquired vision loss. The management for FICE cases included embolectomy, thrombolysis, decompressive craniectomy, antiplatelet/anticoagulant therapy, and symptomatic and nutritional treatment. Nearly half of the patients recovered or exhibited improved neurologic manifestations but not visual loss. Five patients died.

Conclusions

FICE is a severe complication following facial filler injection. Careful prevention, timely identification, and treatment are crucial to decreasing the morbidity and mortality of FICE.

Hypersensitivity Caused by Cosmetic Injection: Systematic Review and Case Report

OBJECTIVE

Botulinum toxin injection, micro-needling injection, and filler injection are the most widely used non-surgical facial cosmetic treatments. Hypersensitivity reactions associated with injections have not received sufficient attention due to their low incidence rates. The authors tried to summarize the characteristics of the hypersensitivity caused by cosmetic injections and helped to improve the diagnosis and treatment.

METHODS

A comprehensive search of the PubMed database to September 2019 was performed. Articles were screened using predetermined inclusion and exclusion criteria. Data collected included patient characteristics, injection information (injected material, trade name, location of injection, symptoms of allergy, time of onset), diagnostic examination, treatment, and prognosis.

RESULTS

A total of 14 articles (57 patients) were included. There were 3 patients receiving botulinum toxin injection, 3 patients receiving micro-needling injection, and 46 patients receiving hyaluronic acid injection. Five patients were injected with collagen, polyacrylamide, paraffin, alkyl-imide or hyaluronidase, separately. The symptoms were redness, swelling, itching or induration at the injection site. The diagnosis and treatment methods vary greatly depending on the injection fillers. Removing the injected filler is the primary treatment.

CONCLUSION

Although hypersensitivity reaction is a relatively uncommon adverse event, more practice guidelines and research on diagnosis and treatment are demanded to help improve the outcomes.

Adverse effects of fillers

Filler injections belong to the most frequently performed noninvasive beautifying procedures. When done correctly they are generally well tolerated. However, a number of factors, such as poor filler quality, and particularly host as well as user dependent filler reactions may lead to unwanted effects. These may be early, late, or delayed events with characteristics for each of them. Temporary fillers almost invariably cause temporary side effects whereas those of permanent fillers may last forever. Some fillers are notorious for their poor safety profile; for example, silicone is banned in the European Union and the United States but nevertheless used by many practitioners and beauticians. Many fillers can be identified in histopathologic sections allowing specific measures to be instituted.

Endoscopic, Ultrasonographic, and Histologic Descriptions of Dextranomer/Hyaluronic Acid in a Case of Fecal Incontinence

OBJECTIVE

To present a case of fecal incontinence treated with dextranomer/hyaluronic acid (Solesta®) injections, which later caused clinical confusion and avoidable interventions. The endoscopic, ultrasonographic, and histologic appearances of dextranomer/hyaluronic acid will also be reported.

CASE PRESENTATION

A middle-aged Hispanic male who failed conservative management of his fecal incontinence was injected with dextranomer/hyaluronic acid in an attempt to alleviate symptoms. An unrelated screening colonoscopy was performed soon after, revealing a submucosal rectal lesion. Flexible sigmoidoscopy and endoscopic rectal ultrasound with FNA were scheduled for patient for further evaluation. An unknown foreign material was noted under microscopy and, upon attaining additional history, the gastroenterologist uncovered the patient's recent injections of dextranomer/hyaluronic acid.

CONCLUSION

Dextranomer/hyaluronic acid for the treatment of fecal incontinence has become more common in recent years. Though the imaging and histologic appearance of this gel-like material is seen in other areas of medicine, equivalent descriptions are limited in the anorectal region. To curb misdiagnoses and prevent unnecessary interventions, it is important to expound on the endoscopic, imaging, and histopathologic features of this tissue-bulking agent in the setting of fecal incontinence and to encourage communication, proper documentation, and easy accessibility to patient health information by all medical staff.

Bilateral Eyelid Pseudoptosis From Lipogranulomas of the Preaponeurotic Fat Pads

Lipogranulomas of the periocular tissues with fulminant fibrotic and lymphohistiocytic responses were initially described in cases of exogenous paraffin or petrolatum jelly injections ("paraffinomas"). A 49-year-old Cambodian woman slowly developed bilateral pseudoptosis with intact levator function and redundant, taut upper eyelid skin. At surgery, vesiculations or "bubbles" in the preaponeurotic fat were encountered and were demonstrated histopathologically to be empty locules surrounded by a thin collagenous lamina. Outside these extracellular spaces were CD68/CD163-positive mononucleated and univacuolated histiocytes simulating damaged fat cells or neoplastic lipoblasts in hematoxylin and eosin sections. Giant cells and chronic sclerosing inflammation were absent. The patient denied any previous injections. The bland character of the lipogranulomas in comparison with that of other injectable agents, the absence of any residual particles associated with other cosmetic fillers, and the distinctive histiocytic response of lipoblast-like cells that were sufficiently characteristic to compel the diagnosis of surreptitious silicone injections. Other conditions were excluded based on comparative clinicopathologic criteria.

Foreign Body Granulomas

A large list of foreign substances may penetrate the skin and induce a foreign body granulomatous reaction. These particles can enter the skin by voluntary reasons or be caused by accidental inclusion of external substances secondary to cutaneous trauma. In these cases, foreign body granulomas are formed around such disparate substances as starch, cactus bristles, wood splinters, suture material, pencil lead, artificial hair, or insect mouthparts. The purpose of this article is to update dermatologists, pathologists, and other physicians on the most recent etiopathogenesis, clinical presentations, systemic associations, evaluation, and evidence-based management concerning foreign body granulomatous reactions of skin.

Managing Complications of Fillers: Rare and Not-So-Rare

Fillers belong to the most frequently used beautifying products. They are generally well tolerated, but any one of them may occasionally produce adverse side effects. Adverse effects usually last as long as the filler is in the skin, which means that short-lived fillers have short-term side effects and permanent fillers may induce life-long adverse effects. The main goal is to prevent them, however, this is not always possible. Utmost care has to be given to the prevention of infections and the injection technique has to be perfect. Treatment of adverse effects is often with hyaluronidase or steroid injections and in some cases together with 5-fluorouracil plus allopurinol orally. Histological examination of biopsy specimens often helps to identify the responsible filler allowing a specific treatment to be adapted.

Delayed immune mediated adverse effects to hyaluronic Acid fillers: report of five cases and review of the literature

Hyaluronic acid (HA) fillers in cosmetic medicine have been considered relatively safe, though fillers used in European countries and throughout the world are not necessarily approved by the Food and Drug Administration. As their use continues to expand worldwide, physicians in a wide range of medical specialties are authorized to perform HA injections, including general medicine practitioners and even dentists. An increasing number of reports have appeared regarding side effects to these products. It is now known that reactions to Hyaluronic acid are related not only to technical faults of the injections, but also to immune responses, including delayed hypersensitivity and granulomatous reactions. Herein, we describe five cases treated by a variety of treatment modalities, all with delayed reactions to different brands of hyaluronic acid fillers. As there is currently no standardization of treatment options of adverse effects, these cases accentuate the debate regarding the approach to the individual patient and the possible need for pre-testing in patients with an atopic tendency.

Cutaneous deposits

: The cutaneous deposition disorders are a group of unrelated conditions characterized by the accumulation of either endogenous or exogenous substances within the skin. These cutaneous deposits are substances that are not normal constituents of the skin and are laid down usually in the dermis, but also in the subcutis, in a variety of different circumstances. There are 5 broad categories of cutaneous deposits. The first group includes calcium salts, bone, and cartilage. The second category includes the hyaline deposits that may be seen in the dermis in several metabolic disorders, such as amyloidosis, gout, porphyria, and lipoid proteinosis. The third category includes various pigments, heavy metals, and complex drug pigments. The fourth category, cutaneous implants, includes substances that are inserted into the skin for cosmetic purposes. The fifth category includes miscellaneous substances, such as oxalate crystals and fiberglass. In this article, the authors review the clinicopathologic characteristics of cutaneous deposition diseases, classify the different types of cutaneous deposits, and identify all the histopathologic features that may assist in diagnosing the origin of a cutaneous deposit.

The utility of C4d immunohistochemistry on formalin-fixed paraffin-embedded tissue in the distinction of polymorphic eruption of pregnancy from pemphigoid gestationis

Polymorphic eruption of pregnancy (PEP), formerly known as pruritic urticarial papules and plaques of pregnancy, is a dermatosis of pregnancy that must be distinguished from pemphigoid gestationis (PG). Although this differential diagnosis may be possible on routine histology, an additional biopsy for direct immunofluorescence (DIF) is often needed. Recent studies have demonstrated the utility of anti-C4d or anti-C3d antibodies in the diagnosis of bullous pemphigoid (BP) in formalin-fixed paraffin-embedded tissue (FFPE). We investigated the utility of routine immunohistochemistry (IHC) for anti-C4d in FFPE tissue in the specific differential diagnosis of PEP versus PG in known, DIF-proven cases. We performed C4d IHC on PEP (n = 11), PG (n = 8), DIF-proven BP (n = 12), and other common dermatoses (n = 12) that are typically DIF negative. None of the PEP cases (0/11) or the other common dermatoses (0/12) demonstrated C4d positivity at the basement membrane zone. In comparison, 100% of PG cases (8/8) and 83.3% of BP cases (10/12) showed linear C4d immunoreactant deposition along the basement membrane zone. The results demonstrate the potential utility of C4d IHC in FFPE tissue for distinguishing PEP from PG, thus potentially obviating the need of a repeat biopsy for DIF, particularly in C4d-negative cases where there is a low suspicion of PG on both clinical and histological grounds. Also, patients with positive C4d-positive immunoreactivity may also potentially proceed directly to less invasive serological confirmatory testing, such as BP180 NC16a enzyme-linked immunoabsorbent assay.

Complications of injectable fillers, part I

Dermal filling has rapidly become one of the most common procedures performed by clinicians worldwide. The vast majority of treatments are successful and patient satisfaction is high. However, complications, both mild and severe, have been reported and result from injection of many different types of dermal fillers. In this Continuing Medical Education review article, the author describes common technical errors, the signs and symptoms of both common and rare complications, and management of sequelae in clear, easily adaptable treatment algorithms.

Histopathologic patterns associated with external agents

A large number of foreign substances may penetrate the skin for both voluntary and involuntary reasons. The voluntary group includes the particulate materials used in tattoos and cosmetic fillers, whereas the involuntary group is almost always caused by accidental inclusion of external substances secondary to cutaneous trauma. This article focuses on the histopathologic findings seen in cutaneous reactions to exogenous agents, with special emphasis on the microscopic morphology of the external particles in recognizing specifically the involved substance (something that is becoming increasingly important in the event of litigation).

[Autologous mesenchymal stem cells culture from adipose tissue for treatment of facial rhytids]

OBJECTIVE

To test the effect of mesenchymal stem cells (MSC) from adipose tissue on the dermal filling for nasolabial rhytids correction.

METHODS

50 cc of infraumbilical fat and 20 ml of peripheral blood were harvested to isolate MSC and autologous plasma from 15 female volunteers, respectively. The volunteers were grouped in according to the following strategies of intra-dermal injection: Group (I) only hyaluronic acid; Group (II) only MSC; Group (III) MSC combined with hyaluronic acid. For this qualitative and prospective study photographic monitoring was done monthly.

RESULTS

In the group (I) we observed an immediate effect of filling; in the group (II) the effect of filling was reached after approximately two months. In the group (III) filling occurred more efficiently and progressively, probably due to the combination of the short and long-term effects generated by the hyaluronic acid and MSC, respectively.

CONCLUSION

MSC when combined with hyaluronic acid were able to fill in deep folds, with progressive improvement of skin tone and decreasing lines of expression.

A case of complication after matridex(r) injection

Matridex(R) is an injectable skin filler that's composed of a mixture of cross linked hyaluronic acid and dextranomer particles, and it was recently developed for soft tissue augmentation. To the best of our knowledge, there have been few previous reports on complications associated with Matridex. We report here on a delayed inflammatory reaction to an injection of Matridex in the glabellar fold, and this developed five weeks after the injection and it lasted more than a year. The patient was treated with oral doxycycline and intralesional injection of triamcinolone acetonide; this resulted in almost complete resolution of the lesion. The patient should be informed of the potential complications with the use of injectable fillers before treatment, for it could lead to undesirable aesthetic consequences.

Immunohistochemistry in the diagnosis of cutaneous neoplasms

In recent years, there has been a significant increase in the number of diagnostic immunohistochemical stains available to pathologists and dermatopathologists. Immunohistochemistry has become an indispensable tool in dermatopathology, not only in diagnosis but also in the treatment and prognostication of cutaneous neoplasms. In this review we attempt to outline current, as well as new, immunohistochemical stains of relevance in the diagnosis and classification of cutaneous neoplasms.
