Abstract
The female reproductive tract undergoes dynamic changes across the life span. Congenital abnormalities, life events, and medical interventions can negatively affect the structure and function of reproductive tract organs, resulting in lifelong sequelae. The objective of regenerative gynecology is to discover and promote endogenous mechanisms by which a healthy tissue maintains overall tissue integrity after injury, after disease, or with age. In this review, we discuss some of the key state-of-the-art cell-based and scaffolding therapies that have been applied to regenerate gynecologic tissues and organs primarily in animal and tissue culture models. We further discuss the limitations of current technologies, problems of implementation and scalability, and future outlook of the field.

Abstract
The past six decades of silicone breast implant history encompass manufacturing secrecy, regulatory laxity, inadequate informed consent, clever advertising, overly simplistic research methodology, diverse and controversial opinions, changing social patterns, safety issues, information ambiguity, speculation, and deception. This review addresses the verifiable clinical, radiological, and pathological aspects of these devices, particularly with regard to silicone bleeding. This information can favorably assist practitioners and radiologists facing diagnostic challenges encountered in patients with silicone breast implants.

Abstract
Breast implant illness refers to a combination of different symptoms related to breast implant surgery, including fatigue, brain fog, and arthralgias. This malaise occurs after cosmetic and reconstructive breast surgeries, although it has not been proven to be a disease. Even recent studies have reported concluding statements of the etiology, diagnosis, and treatment as unclear and widely unknown. Therefore, this review aimed to determine the associations between the manifestations of breast implant illness in surgery and breast reconstruction, as well as the autoimmune responses involved. Complications associated with breast implants include breast pain, capsular contracture, infections, as well as other manifestations specific to breast reconstruction. Moreover, patients with implants may present with new-onset systemic sclerosis, Sjögren’s syndrome, and connective tissue diseases. However, the incidence of capsular contracture has steadily decreased with each generation of implants, particularly since the development of textured implants, as well as with the use of antibiotics and antiseptic pocket irrigation. However, the incidence of anaplastic large cell lymphoma has increased with the use of textured implants. Remarkably, the autoimmune response to these implants remains unclear. Therefore, close follow-up, careful observation of any symptom presentation, and evidence-based treatment decisions are necessary for patients with breast implants.

Abstract
For patients with breast implants who present with an isolated seroma, capsular contracture, or peri-implant mass, clinicians must rule out breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). As non-malignant silicone-induced granuloma of breast implant capsule (SIGBIC) may mimic BIA-ALCL, particular care must be exercised to prevent misdiagnosis. In this report, we describe three cases of SIGBIC misdiagnosed as BIA-ALCL. In each of these cases, a preoperative evaluation including breast magnetic resonance imaging and physical examination, as well as the fact that a textured silicone implant was used in the patients, indicated a high probability of malignancy. In all three cases, however, an explorative operation and pathologic results revealed foreign body granulomas without malignant features. While it is critical that potential cases of BIA-ALCL be diagnosed and treated quickly, hasty judgments may lead to misdiagnosis and severe emotional distress in patients. Increased awareness of SIGBIC, specifically its mimicry of BIA-ALCL, may be helpful to avoid these outcomes.

Abstract
Complications related to breast implants have received much attention recently. Breast implant-associated anaplastic large cell lymphoma, silicone-induced granuloma of breast implant capsule, and breast implant illness are the main complications reported in the medical literature. However, the literature contains limited evidence regarding the possibility of silicone implants eliciting breast carcinoma. In this manuscript, we propose a theory in which the immune response to silicone breast implant gel bleeding acts as a triggering point for tumor oncogenesis in breast tissue. This hypothesis is derived from our findings of a case of invasive and undifferentiated medullary carcinoma in a patient with a silicone breast implant. The following concepts have been used to support this theory: 1) silicone bleeding from intact breast implants; 2) metaplasia: an adaptation to injury and precursor to dysplasia and cancer; 3) T-cell dysfunction in cancer immunity; 4) inhibitory cells in the tumor microenvironment (TME); 5) morphogenesis and bauplan; and 6) concepts underlying medullary carcinoma. We propose that the inflammatory process in response to silicone particles in the pericapsular glandular tissue favors the development of cellular mutations in specialized epithelial cells. This reverse morphogenesis could have resulted in breast carcinoma of the medullary type in the present case.

Etiology of Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL): Current Directions in Research. Cancers (Basel) 2020; 12:cancers12123861.

Abstract
Simple Summary The first report of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) was in 1997. Although BIA-ALCL develops around breast implants, it is considered a cancer of the immune system and not a cancer of the breast ducts or lobules. Nearly all confirmed cases to date have been associated with textured surface (versus smooth surface) breast implants. As physicians have become more aware of BIA-ALCL, so has the number of reported cases, although the number of cases remains low. In most instances, patients have an excellent prognosis following removal of the breast implant and its surrounding fibrous capsule. Many theories on factors that trigger the development of BIA-ALCL, such as the presence of bacteria, have been proposed. However, the sequence(s) of events that follow the initial triggering event(s) have not been fully determined. This article summarizes the current scientific knowledge on the development of BIA-ALCL. Abstract Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a CD30-positive, anaplastic lymphoma kinase-negative T-cell lymphoma. Where implant history is known, all confirmed cases to date have occurred in patients with exposure to textured implants. There is a spectrum of disease presentation, with the most common occurring as a seroma with an indolent course. A less common presentation occurs as locally advanced or, rarely, as metastatic disease. Here we review the immunological characteristics of BIA-ALCL and potential triggers leading to its development. BIA-ALCL occurs in an inflammatory microenvironment with significant lymphocyte and plasma cell infiltration and a prominent Th1/Th17 phenotype in advanced disease. Genetic lesions affecting the JAK/STAT signaling pathway are commonly present. Proposed triggers for the development of malignancy include mechanical friction, silicone implant shell particulates, silicone leachables, and bacteria. Of these, the bacterial hypothesis has received significant attention, supported by a plausible biologic model. In this model, bacteria form an adherent biofilm in the favorable environment of the textured implant surface, producing a bacterial load that elicits a chronic inflammatory response. Bacterial antigens, primarily of Gram-negative origin, may trigger innate immunity and induce T-cell proliferation with subsequent malignant transformation in genetically susceptible individuals. Although much remains to be elucidated regarding the multifactorial origins of BIA-ALCL, future research should focus on prevention and treatment strategies, recognizing susceptible populations, and whether decreasing the risk of BIA-ALCL is possible.

Abstract
Objective To evaluate the sensitivity (S) of BMRI to detect silicone gel bleeding in a prospective observational study, including consecutive patients referred for BMRI scan. Methods From January 2017 to March 2018, we evaluated patients with breast implants referred for BMRI in a prospective observational study. For SIGBIC diagnosis, we adopted three new original imaging features: black drop signal; T2* hyper signal mass; and delayed contrast enhancement, considered as irrevocable signs to detect gel bleeding (GB). Histology confirmed the presence of a silicone corpuscle in breast implant capsular specimens. The accuracy of BMRI SIGBIC findings to predict GB was determined. We also compared SIGBIC diagnosis criteria to those features proposed by the BI-RADS léxicon, considered as equivocal findings. Results 208 patients had SIGBIC diagnosis at BMRI, and the histology confirmed GB in all cases. There were no false-positive results. Compared to the BI-RADS equivocal findings (S = 0.74), SIGBIC criteria had better sensitivity for GB diagnosis. Conclusion SIGBIC diagnosis has high sensitivity to predict GB by the three irrevocable BMRI features described by the authors. We suppose GB is underdiagnosed in clinical practice by BI-RADS features. Trial certification Study protocol: Plataforma Brasil CAAE: 77215317.0.0000.0072.

Abstract
Millions of women worldwide have silicone breast implants. It has been reported that implant failure occurs in approximately a tenth of patients within 10 years, and the consequences of dissemination of silicone debris are poorly understood. Currently, silicone detection in histopathological slides is based on morphological features as no specific immunohistochemical technique is available. Here, we show the feasibility and sensitivity of stimulated Raman scattering (SRS) imaging to specifically detect silicone material in stained histopathological slides, without additional sample treatment. Histology slides of four periprosthetic capsules from different implant types were obtained after explantation, as well as an enlarged axillary lymph node from a patient with a ruptured implant. SRS images coregistered with bright-field images revealed the distribution and quantity of silicone material in the tissue. Fast and high-resolution imaging of histology slides with molecular specificity using SRS provides an opportunity to investigate the role of silicone debris in the pathophysiology of implant-linked diseases.

Abstract
Since 2017, there have been an increasing number of reported cases regarding breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) in the literature. Although significant attention was dispensed for this relevant issue, there is no consensus on what the trigger points for disease development are. BIA-ALCL trigger point speculation includes textured breast implants, bacterial contamination, and genetic factors. However, little attention is given by the literature regarding gel bleeding and the toxicity of polydimethylsiloxane. This opinion-based article aims to report our experience in a prospective study of breast implants and share our knowledge regarding silicone-induced granuloma of breast implant capsule.

Abstract
In the present review, recent findings regarding autoimmune/inflammatory syndrome by adjuvants (ASIA) are described. Patients with ASIA present with complaints such as fatigue, cognitive impairment, arthralgias, myalgias, pyrexia, dry eyes and dry mouth. During the last few years, it has been postulated that these symptoms in patients with foreign body implants are due to a chronic inflammatory process and an adjuvant effect of the implanted biomaterial. Ultimately, these inflammatory reactions result in (an increase of) allergies, autoimmune diseases, immune deficiency and/or lymphomas. Pre-existent allergic disease has been found to be an important risk factor for the development of ASIA after foreign body implantation. Explantation of the foreign body results in the majority of patients in an amelioration of the symptoms. There is an urgent need to start adequately adjusted epidemiological studies to obtain better evidence which percentage of patients does develop symptoms and/or diseases such as ASIA, immune deficiency, and/or autoimmune diseases after implant surgery.

Abstract
Currently, attention has been given to complications related to breast implants, especially due to the presence of anaplastic large cell lymphoma (ALCL) related to silicone implants. Many manuscripts attempt to associate silicone presence with clinical complaints reported by patients, while others try to demonstrate the mechanisms of silicone bleeding by permeability loss of breast implant surfaces. There also are reports of foreign body type reactions from implant fibrous capsule to silicone corpuscles. However, there seems to be no study that correlates the clinical, radiological, and histological correlations of these lesions. The objective of this review is to correlate radiological findings of silicone-induced granuloma of breast implant capsule (SIGBIC) from breast MRI (BMRI) scans and complementary findings of ultrasound (US) and positron emission tomography (PET) scan, and its histology originated from surgical breast implant capsulectomy. To make this correlation possible, we divided SIGBIC into three radiological findings: (1) intracapsular SIGBIC, (2) SIGBIC with extracapsular extension, and (3) mixed SIGBIC associated with seroma. Our experience demonstrates histological-radiological correlation in SIGBIC diagnosis. Knowledge of these findings may demonstrate its real importance in terms of public health and patient management. We believe that SIGBIC is currently underdiagnosed by lack of training, guidance, and management in our clinical practice.

Abstract
Background: To determine whether there is correlation between magnetic resonance imaging (MRI) findings and breast elastography to differentiate seroma/hematoma from silicone-induced granuloma of breast implant capsule (SIGBIC). Methods: Prospective study of 99 patients with breast implants submitted to breast MRI during the period from February 1 to May 1, 2017. Patients who present MRI findings of seroma/hematoma or SIGBIC were submitted to a complementary ultrasound elastography study to evaluate the correlation of the results. The criteria adopted for the diagnosis of granuloma by MRI were heterogeneous hypersignal in the T2-weighted sequences, late contrast enhancement, and black drop sign. Lesions that did not enhance after the use of contrast were considered as seroma/hematoma. By elastography, the results were considered positive for granuloma when presented as hard lesions, whereas seroma/hematoma presented as soft lesions. Results: Of the 99 patients evaluated, 15 were included in the study. Of the 15 patients, 9 had solid intracapsular MRI masses, whereas 6 presented collections without contrast enhancement. The complementary elastography study showed correlation with MRI results in all cases of SIGBIC and seroma/hematoma, being elastography able to differentiate lesions from solid to cystic. Conclusions: Elastography of intracapsular masses in breast implants presented results compatible with those found by MRI to differentiate solid lesions from collections.

Abstract
Complications resulting from the placement of silicone breast implants are becoming more frequent in our clinical practice. This is due to the increase in breast aesthetic surgeries at the beginning of the century, where breast augmentation using silicone implants was the main intervention performed. Generally, studies that discuss the complications of breast implants are restricted to reports of intra- or extra-capsular ruptures, contractures and haematomas. Currently, much importance has been given to anaplastic large cell lymphoma (ALCL) as a more severe complication related to silicone implants. Recently, granuloma formation induced by silicone particle bleeding from intact breast implants has been described when the free silicone comes into contact with the fibrous capsule of the implant. Few studies have demonstrated the characteristics and diagnostic keys for this entity. The objective of this study is to present cases of SIGBIC diagnosed in our service and to discuss the main findings that allow its diagnosis. Teaching Points • Breast implants induce fibrous capsule formation at the periphery of the implant. • Gel bleeding is inherent in all types of silicone breast implants. • Gel bleeding induces silicone-induced granuloma of breast implants. • Main diagnostic tips: heterogeneous mass, black-drop sign and late enhancement.
