Silicone Granulomas of the Eyelids-A Case Series Illustrating a Distant Migratory Phenomenon.

PURPOSE: Exogenous silicone has been reported to migrate to anatomic sights far from an initial injection or implantation site; this phenomenon has been rarely described in the ocular adnexa, especially in the eyelids. We document 3 additional cases of distant migration of silicone implanted elsewhere in the body to the eyelids and review the prior literature on this uncommon event. METHODS: A retrospective chart review of 3 patients was conducted along with analysis of diagnostic histopathology. A comprehensive review of the literature regarding dissemination or migration of silicone to the eyelids in patients with either silicone breast implants or silicone facial filler use was performed. RESULTS: Cases of silicone migrating to the eyelids from silicone breast implants and silicone-based facial filler are outlined in Tables 1 and 2, respectively. There are 4 total reports of women with silicone breast implants, including the 2 described here, with evidence of migration of silicone to the eyelid. Similarly, 5 cases of silicone-based facial filler with resultant migration of filler to the eyelids were identified, including 2 of the cases presented in this report (1 patient had both silicone breast implants and silicone facial filler). CONCLUSION: Silicone is chemically inert, but is known to travel throughout the body, causing a resultant foreign body response in tissue that can adversely affect even the eyelids. Silicone has a relatively characteristic histologic appearance and diagnosis of silicone granuloma highlights the importance of obtaining a thorough clinical history, particularly regarding prior cosmetic injections or breast enhancement surgery. Foreign material/foreign body granuloma is important to consider in patients with deep eyelid nodules of unclear etiology.

Adverse reactions to the injection of face and neck aesthetic filling materials: a systematic review.

BACKGROUND: Adverse reactions, caused during the inflammation and healing process, or even later, can be induced by the injection of dermal filler and can present a variety of clinical and histological characteristics. In this study we aimed to review the adverse reactions associated with the injection of aesthetic filling materials in the face and neck. MATERIAL AND METHODS: The review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Studies published that mentioned adverse reactions in patients with aesthetic filling materials in the face or neck were included. Risk of bias was assessed using the Joanna Briggs Institute appraisal tool. After a 2-step selection process, 74 studies were included: 51 case reports, 18 serial cases, and five cohorts. RESULTS: A total of 303 patients from 20 countries were assessed. Lesions were more prevalent in the lip (18%), nasolabial folds (13%), cheeks (13%), chin (10%), submental (8%), glabella (7%), and forehead (6%). Histopathological analysis revealed a foreign body granuloma in 87.1% of the patients, 3% inflammatory granuloma, 3% lipogranuloma, 2.3% xanthelasma-like reaction, 1% fibrotic reaction, 0.7% amorphous tissues, 0.7% xanthelasma, 0.3% sclerosing lipogranuloma, 0.3% siliconoma, and 0.3% foreign body granuloma with scleromyxedema. In addition, two patients displayed keratoacanthoma and two others displayed sarcoidosis after cutaneous filling. The most commonly used materials were silicone fillers (19.7%), hyaluronic acid (15.5%), and hydroxyethyl methacrylate/ethyl methacrylate suspended in hyaluronic acid acrylic hydrogel (5.6%). All patients were treated, and only 12 had prolonged complications. CONCLUSIONS: There is evidence that adverse reaction can be caused by different fillers in specific sites on the face. Although foreign body granuloma was the most common, other adverse lesions were diagnosed, exacerbating systemic diseases. In this way, we reinforce the importance of previous systemic evaluations and histopathological analyses for the correct diagnosis of lesions.

Pulse Granuloma-Like Reaction on the Forearm Following an Accidental Wound.

ABSTRACT: Pulse granulomas are uncommon reactions to vegetable exogenous matter characterized by the presence of hyaline rings. Although they are usually found in the oral cavity or along the gastrointestinal or respiratory tracts, there are a few cases described outside those regions. We present the first case of a granulomatous reaction with hyaline rings in the skin reaction after an accidental wound and suggest the term pulse granuloma-like to describe lesions that resemble pulse granulomas but with no connection to the gastrointestinal or respiratory tracts. Moreover, we provide a graphic comparison of the hyaline rings observed in our case and the histologic sections of some plants that could have been involved.

Silicone Granulomas at the Peripheral Intravenous Cannula Puncture Site.

ABSTRACT: Different adverse reactions to silicone present in cosmetic fillers, implants, or medical devices have been reported. The granulomatous reaction on the injection site due to catheters' silicone coating is an infrequent complication, which may be clinically difficult to suspect. Although the definitive diagnosis requires identification of the silicone with techniques such as X-ray spectroscopy, the possibility of involvement of silicone, as well as the histopathologic demonstration of granulomas with refractile, nonpolarizable, and nonstainable material strongly suggests this diagnosis. Moreover, the use of a low-diaphragm aperture or phase-contrast microscopy could be useful to demonstrate the presence of this, otherwise almost transparent, foreign body.

Absence of multinucleated giant cell reaction as an indicator of tumor progression in oral tongue squamous cell carcinoma.

PURPOSE: The aim of this study was to evaluate the presence and distribution of multinucleated giant cell (MGC) reactions in 61 cases of OTSCC and to verify the association of this microscopic finding with clinicopathological parameters (gender, age, tumor size/extent, regional lymph node metastasis, distant metastasis, clinical stage, and histopathological grade of malignancy). METHODS: Clinical data were collected from medical records and the histopathological grade of malignancy of OTSCCs was evaluated using the World Health Organization (WHO) grading system. The presence and distribution of MGC reaction in high power fields (HPFs) were evaluated in hematoxylin-eosin-stained histological sections. In all cases containing MGCs, immunohistochemical analysis for CD68 was performed in order to confirm the histiocytic nature of these cells. RESULTS: Twenty-one (34.4%) cases had MGC reactions, with a higher frequency of the focal distribution pattern (57.1%). All MGCs were immunohistochemically positive for CD68. The absence of MGC reaction was significantly associated with regional lymph node metastasis (PR: 2.75; 95% CI 1.05-7.20; p = 0.027), advanced clinical stage (PR: 3.37; 95% CI 1.28-8.85; p = 0.006), and moderately/poorly differentiated tumors (PR: 3.36; 95% CI 1.51-7.48; p = 0.001). No significant associations were observed between the distribution of MGCs and clinicopathological parameters (p > 0.05). CONCLUSION: Taken together, the results of this study suggest that the absence of MGC reaction may represent an indicator of tumor progression in OTSCCs.

A case of oral foreign-body granuloma due to diatoms.

Diatoms are photosynthetic algae with a siliceous exoskeleton. Diatoms are utilized by a wide array of industries for applications such as filtration and pest control. Unsubstantiated claims have also propelled their societal reach to trendy oral and topical uses. This case highlights a rare case of an oral granuloma secondary to diatoms. An 80-year-old woman presented with a mobile, firm, asymptomatic submucosal mass on her lower left mandibular vestibular mucosa. Histopathology showed a non-caseating granulomatous reaction to diatoms. Her only verified contact with a diatomaceous earth product was a dental impression using alginate after upper front teeth trauma 5 months before. Although there have been several cases of allergic contact dermatitis attributed to diatoms, there are no reported cases of diatom-induced granuloma formation found in the literature. There are, however, ample data on granulomas initiated by silica. Given the silica-based composition of diatoms, and the broad use of diatoms in industry and alternative medicine, it is unclear why diatom-induced granulomas are not more widely described. This report may alert clinicians to the existence of diatom granulomas and incline them to tailor their history to cover questions about possible exposure when evaluating patients presenting with a localized oral lesion.

MRI findings for diagnosis of postoperative foreign body granulomas versus recurrent tumours in patients of brain tumour surgery.

AIM: To evaluate the postoperative magnetic resonance imaging (MRI) findings of intracranial foreign body granulomas (FBGs) and true recurrent tumours (RTs) and thus lead to a basis for management decision-making. MATERIALS AND METHODS: Twenty-two patients with previous brain tumour surgery were diagnosed clinically with RT and underwent surgery. Re-operative pathology revealed FBG in eight patients and RT in 14 patients. MRI findings before the initial operation were compared to those before the re-operation. RESULTS: Features of FBGs versus RTs on MRI were as follows: (1) mean lesion size: 1.3 ± 0.7 (0.5-2.6) versus 3.2 ± 1.7 (1.1-6.3) cm (p=0.001, odds ratio [OR] = 4.18); (2) hypointensity on T2-weighted imaging (WI): 6/8 (75%) versus 0/14 (0%; p<0.001, OR=75.4); (3) non-restricted diffusion on diffusion-WI (DWI): 6/8 (75%) versus 2/14 (14.3%; p=0.008, OR=18); and (4) "ring and bubble" appearance on contrast-enhanced T1WI: 7/8 (87.5%) versus 2/14 (14.3%; p=0.001, OR=42). In comparison with their original tumours, the FBGs in the FBG group showed significantly lower T2 signal intensity, lower signal on DWI, and more cases of non-restricted diffusion on DWI (p=0.04, 0.04, 0.04, respectively). CONCLUSION: On brain MRI, FBGs can be differentiated from RTs by their relatively smaller size, hypointensity on T2WI, lack of restricted diffusion on DWI, and "ring and bubble" appearance on contrast-enhanced T1WI. Comparing the MRI findings of the focal lesion in the tumour bed with those of the original tumour is suggested to enhance diagnostic confidence.

An Overview of the Derivation and Function of Multinucleated Giant Cells and Their Role in Pathologic Processes.

Monocyte lineage cells play important roles in health and disease. Their differentiation into macrophages is crucial for a broad array of immunologic processes that regulate inflammation, neoplasia, and infection. In certain pathologic conditions, such as foreign body reactions and peripheral inflammatory lesions, monocytes fuse to form large, multinucleated giant cells (MGCs). Currently, our knowledge of the fusion mechanisms of monocytes and the regulation of MGC formation and function in discrete pathologies is limited. Herein, we consider the types and function of MGCs in disease and assess the mechanisms by which monocyte fusion contributes to the formation of MGCs. An improved understanding of the cellular origins and metabolic functions of MGCs will facilitate their identification and ultimately the treatment of diseases and disorders that involve MGCs.

Vulvar Silicone Granuloma.

We report a case of vulvar silicone granulomas following injection of liquid silicone into the labia. The patient is a 51-yr-old female who presented with vulvar pain and enlarged, indurated labia majora. In the past, she had undergone bilateral labial cosmetic augmentation with a silicone-based filler injected directly into the labia and into the gluteal regions. This had been performed in a nonmedical setting. At surgery, oblong firm soft tissue masses were removed from both labia. Microscopically, the lesions demonstrated replacement of the subcutaneous adipose tissue by fibrous tissue containing innumerable round empty spaces of different sizes, either within or surrounded by macrophages and occasional foreign-body giant histiocytes. The clear vacuoles corresponded to silicone fluid which had been dissolved during tissue processing. There are only rare case reports of vulvar silicone granuloma in the literature, and these were due to migration of silicone to the vulva from distant sites. Our report details a case of vulvar silicone granuloma secondary to direct injection of liquid silicone material into the labia.

Polymethylmethacrylate-induced nodules of the lips: Clinical presentation and management by intralesional neodymium:YAG laser therapy.

The lips are essential part of the beauty and attractiveness of the human face. Lip augmentation has become an increasingly used method to improve appearance. Soft tissue fillers are the most commonly used tools. Permanent fillers, however, have been associated with unwanted side effects after lip augmentation. In the present article the present authors will focus on permanent fillers based on polymethylmethacrylate (PMMA). The present authors provide a short review on PMMA fillers and known associated adverse events. The present authors provide a critical review of treatment options. Illustrated by clinical cases The present authors report our preferred treatment of PMMA nodules on lips by intralesional neodymium:YAG laser and blunt suction cannula with or without minor surgery.

Granuloma as a complication of polycaprolactone-based dermal filler injection: ultrasound and histopathology studies.

In aesthetic medicine, there has been an ongoing search for an ideal dermal filler to offer zero complication rate. Polycaprolactone-based dermal filler (PCL) has been available since 2009. The purpose of the paper was to present a case of granuloma as a complication of PCL injection, which has not been reported so far by other researchers. A 68-year-old female was injected with PCL. One year later, nodules accompanied by bluish skin discoloration developed within the injection site. Ultrasound and histopathology studies were performed. The examinations confirmed the presence of foreign body granuloma after PCL, which makes it the first reported case worldwide. The published data analyses showed general lack of studies and case reports to address this issue. The PCL, like an injection of any soft tissue filler, may lead to serious complications, such as granuloma formation. This makes further research legitimate and necessary.

Labial paraffinoma in menopause women.

Age-related changes in menopause women not only affect the physical appearance of the female external genitalia but also disrupt sexual functioning, for which many menopause women may require treatment to resolve these aesthetic problems or sexual dysfunction. Unfortunately, it is not infrequent that women seek non-medical solutions, including local injection of an unapproved agent into external genitalia, and it is extremely rare for it to be reported in literature. This case study reports on the experiences of treating two menopause women who had labial granuloma induced by local injection of paraffin.

The case of the eyelid silicone granulomas.

Foreign body granulomas can develop even several years after autologous fat or filler injection. In some instances the foreign body granulomas have been found at sites other than the original injection site. We present a case of a 48-year-old male with reported "hyaluronic acid fillers" injected into his upper and lower eyelids several years prior. He subsequently developed periorbital swelling with negative allergic and rheumatologic workup. The patient ultimately underwent a blepharoplasty for improvement of the swelling. Histopathology suggested silicone granulomas of the upper and lower eyelid. This case illustrates the importance of keeping foreign body granulomas on the differential for all patients with a history of facial dermal filler injections. Although hyaluronic acid is the most common dermal filler, providers should suspect the use of other dermal fillers including those not FDA approved particularly when common conservative treatment methods are not sufficient.

Granulomatous Inflammation of the Upper Eyelid After Autologous Fat Injection.

A 45-year-old female came to the clinic complaining of periorbital swelling and ptosis on the left upper eyelid that had started 6 months previously. She had received an autologous fat injection in the forehead 6 months prior, and there was no other ophthalmologic history. There were no abnormal findings, including pupil, extraocular movement, or fundus examination. There was eyebrow elevation of the left upper eyelid, and the marginal reflex distance 1 was 1 mm on the left eye compared to 4 mm on the right eye. There were a 2-cm-sized round and firm mass on the left upper eyelid that was not accompanied by tenderness. Orbital computed tomography showed heterogeneous infiltration with an ill-defined margin. Excisional biopsy and levator advancement were performed on the left upper eyelid, and histological findings showed chronic granulomatous inflammation with foreign body reaction and fat necrosis.A complete history for patient presentation with autologous fat injection is important when a periorbital mass is encountered clinically because granulomatous inflammation of the eyelid may occur after autologous fat injection in the forehead and can be related to migration of the injected fat.

Lethal silicone embolization syndrome complicating penile, scrotal and breast self-augmentation.

A 62-year-old man died following injection of liquid silicone into his external genitalia and chest wall. The body was discovered naked, apart from a pair of black women's high-heeled shoes, black ankle restraints, which were chained together, and disposable medical gloves. Medical items in the house included syringes, needles, alcohol wipes and unmarked/labelled empty brown glass medical bottles. At autopsy the external genitalia were markedly enlarged with white dressings over injection sites in the scrotum, penis and above the left nipple. Histological examination of the scrotum, penis and breast showed a florid granulomatous foreign body giant cell reaction and scarring surrounding numerous optically clear vacuoles. The lungs also showed numerous vacuoles within the interstitium in keeping with embolization of injected material. Death was due to silicone embolization. Despite the dangers of liquid silicone injections for soft tissue augmentation, and the ban on its use for medical cosmetic procedures, this practice continues.

Effect of anti-inflammatory activity of ranolazine in rat model of inflammation.

BACKGROUND & OBJECTIVES: Inflammatory processes are a recognized feature of atherosclerotic lesions. Ranolazine inhibits the inflammatory markers such as C-reactive protein, interleukins-1 and -6 and tumour necrosis factor-alpha. The present study was planned to evaluate the effect of anti-inflammatory activity of ranolazine in acute and sub-acute models of inflammation in rats and compare the same with that of control (gum acacia 1%) and aspirin (standard anti-inflammatory drug). METHODS: Adult male Wistar rats (150-180 g) were used for the study. They were divided into three groups (n=6). One per cent gum acacia (control), aspirin (200 mg/kg body weight) and ranolazine (180 mg/kg body weight) were given orally. Acute inflammation was induced by injecting carrageenan in the left hind paw. Paw oedema volume and percentage inhibition were measured. Subacute inflammation was induced by implanting foreign bodies subcutaneously. Percentage inhibition of granuloma dry weight and haematoxylin and eosin stained sections of granulation tissue were studied. RESULTS: In acute and subacute model study, ranolazine significantly (P <0.01) decreased the paw oedema volume and granuloma dry weight as compared to control and it was comparable to that of aspirin and histopathological sections showed a decrease in granulation tissue formation as compared to control. INTERPRETATION & CONCLUSIONS: Ranolazine demonstrated significant anti-inflammatory activity in acute and subacute models of inflammation and needs further evaluation for its use in reducing atherosclerosis.

High-frequency ultrasound-based differentiation between nodular dermal filler deposits and foreign body granulomas.

BACKGROUND: The number of procedures involving dermal filler injection is still on the rise. Although their safety is improving, not all complications can be avoided. The late complications manifesting as nodules or granulomas pose a particular diagnostic and therapeutic challenge, due to the lack of uniform standards or guidelines. High-frequency, ultrasound imaging appears to be a useful method for distinguishing between granulomas and nodular dermal filler deposits. AIM: The aim of the paper was to evaluate the utility of high frequency ultrasound imaging for distinguishing between foreign body granulomas and nodular dermal filler deposits. MATERIAL AND METHODS: Eleven females aged 21-66 years (mean age of 43.6 years old) who had soft tissue fillers injected were enrolled. All patients had a high-frequency ultrasound scan of the involved skin area performed. The shape, margins, area, location and echogenicity of the lesions were assessed. Additionally, the lesions were evaluated histologically and photographs were taken. RESULTS: The analysis indicated differences between the ultrasound image of granulomas and dermal filler deposits. Characteristic ultrasound features of granulomas include oval shape and blurred, irregular outer edges. Small hyperechoic areas were seen inside the granulomas. The deposits were anechogenic, with sharp, regular borders. CONCLUSIONS: High-frequency ultrasound imaging enables distinguishing between granulomas and nodules-dermal filler deposits, which form after dermal filler injections.

Tattoo-associated uveitis with or without systemic sarcoidosis: a comparative review of the literature.

Sarcoidosis is a systemic disease of unknown aetiology characterized by the presence of non-caseating epithelioid cell granulomas in multiple organs, mainly the lungs and the lymphatic system. It is also one of the leading cause of inflammatory eye diseases. For the past 70 years, sarcoidal granulomas on tattoos and permanent make-up have been documented. They can be the first and sometimes unique cutaneous manifestation of systemic sarcoidosis. A few cases of sarcoidosis with uveitis and granulomatous reactions within tattoos have been described. However, since the end 60s, a singular entity has been reported associating isolated uveitis with granulomatous cutaneous reaction restricted to tattoos in the notable absence of systemic sarcoidosis. It remains unclear whether this entity must be distinguished from sarcoidosis. This review summarizes the currently available data on this topic and compares cases of sarcoidosis with granulomatous tattoo reaction and uveitis to the cases without notable sarcoidosis. We propose the acronym TAGU (TAttoo Granulomas with Uveitis) as an exclusion diagnosis that emcompasses the patients for whom we fail to find any sarcoidosis or other causes after extensive investigation.

Schistosomiasis (Bilharziasis) ova: An incidental finding in testicular tissue of an obstructive azoospermic man.

Congenital bilateral absence of vas deferens (CBAVD) results in obstructive azoospermia in which testicular function, such as spermatogenesis, is preserved. Bilateral testicular biopsy is not only diagnostic but also therapeutic as retrieved spermatozoa are usually cryopreserved for assisted reproduction. In this case report, CBAVD was confirmed in a 24-year-old azoospermic man on the basis of persistent azoospermia associated with low semen volume, absent fructose and normal hormonal levels, ultrasonographically (absent seminal vesicles) and histologically (intact spermatogenesis). Interestingly and incidentally, only the right testicular biopsy showed ova of two parasitic species of Schistosoma, namely Schistosoma haematobium which infests the genitourinary tract and Schistosoma mansoni which infests the gastrointestinal tract. Both species are rare causes of azoospermia, and the case should be further managed as CBAVD in which the left testicle is considered the preferred site of sperm retrieval for assisted reproduction.

Dermalive Facial Filler Granulomas Masquerading as Neurofibromas.

A 56-year-old woman presented with periocular nodules that were clinically suspected to be neurofibromas. Histopathologic examination of excised nodules revealed a pronounced granulomatous reaction to a foreign material that was composed of glossy polygonal palely eosinophilic fragments. These fragments were outlined in red with Masson trichrome, stained gray with the elastic stain, and were uniformly red with Gomori methenamine silver staining. The histopathologic appearance was consistent with a granulomatous reaction to Dermalive facial filler. Postoperatively the patient admitted that she had filler injections many years earlier in another country, and that nodules appeared 1 year after injection. Treatment with steroids, intralesional immunosuppressive agents and surgery had been previously attempted to eradicate the nodules. The literature pertaining to granulomatous reactions to Dermalive and related hybrid facial fillers is reviewed and treatment options are discussed. This report is the first to illustrate the unique histopathologic staining characteristics of Dermalive, which may be useful to ophthalmic pathologists in identifying this uncommon foreign material.
