In this study, an unusual case of a patient who was previously operated on a ruptured breast implant following silicone granuloma associated with pectoral muscle involvement is reported. A 72-year-old woman had undergone breast augmentation surgery when she was 52-year-old and silicone implant rupture 10 years later. After 10 years of ruptured silicone implant, her mammography showed diffuse, multiple high-density nodules in the left breast. The pectoral muscle was significantly hypertrophic. The magnetic resonance imaging showed that the pectoral muscle was quite hypertrophic and had heterogeneous enhancement...

INTRODUCTION: The introduction of acellular dermal matrices (ADMs) contributed to the growing diffusion of direct-to-implant breast reconstruction (DTI-BR) following mastectomy for breast cancer. According to specific legislations, European specialists could not benefit from the use of human-derived ADMs, even though most evidence in the literature are available for this kind of device, showed optimal outcomes in breast reconstruction. The Skin Bank of the Bufalini Hospital (Cesena, Italy) obtained in 2009 the approval for the production and distribution of a new human cadaver-donor-derived ADM (named with the Italian acronym, MODA, for matrice omologa dermica acellulata) from the Italian National Transplant Center and National Health Institute...

Fibromatosis is a benign tumor that rarely affects the breast and is an unusual site for its occurrence. Whilst the definite etiology of breast fibromatosis is unclear, it may present itself following surgical trauma or silicone implant. Wide local excision with adequate safety margins is considered the standard of care. We review three cases of breast fibromatosis who were presented to and operated in the Oncology center, Mansoura universty (between April 2014 and August 2016). Two of these cases underwent wide local excision and primary closure of the defect whilst the other one was reshaped by mini latismuss dorsi flap...

Silicone implants are widely used in aesthetic and reconstructive breast surgery. Silicone lymphadenopathy is a well-known rare complication of implant insertion. Silicone leakage from a rupture or silicone bleeding can accumulate in lymph nodes. Foreign body reactions in the affected lymph nodes may be misdiagnosed as metastasis or malignant lymphadeno pathy upon initial presentation if silicone lymphadenopathy is not considered in the initial diagnosis. We report a case of siliconoma with extensive involvement of multiple lymph nodes mimicking malignant features to emphasize that clinicians should carefully evaluate each patient's medical history and disease status during differential diagnosis...

Breast implant-associated anaplastic large T-cell lymphoma has recently been recognized as an entity, with few reports describing the two common subtypes: in situ (indolent) and infiltrative. Recently, the infiltrative subtypes have been shown to be more aggressive requiring adjuvant chemotherapy. We report a rare case of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) in a 65-year-old Caucasian female following silicone breast implantation and multiple capsulectomies. We discuss the rare presentation of this disease, histopathologic features of the indolent and infiltrative subtypes of ALCL, and their clinical significance...

BACKGROUND: Silicone breast implants from the French manufacturer Poly Implants Prosthèse (PIP) were recalled from the European market after the French regulator has revealed the implants contain non-medical-grade silicone filler. In December 2011, following a large increase in reported rupture rate and a possible cancer risk, the French Ministry of Health recommended consideration of the PIP explantation, regardless of their condition. In 2012, the Israel Ministry of Health recommended to replace the implants only upon suspected implant rupture...

BACKGROUND: The phyllodes tumour of the breast comprises about 0.5% of all neoplasms of the breast. CASE REPORT: we present the case of a female patient (55 years old) suffering from giant phyllodes tumour (>10cm) of the left breast, who underwent Skin Reducing Mastectomy (SRM) and reconstruction with silicone breast implant (Bostwick Technique). DISCUSSION AND CONCLUSION: In selected patients with large sized breasts (C-D cup) and poor surface area of skin involved, a valid technique in the treatment of this pathology is the Skin-Reducing Mastectomy and immediate reconstruction with implants (DTI=direct to implant)...

The aim of the current study was to determine whether the MWCNT-based scaffold has a suitable structure for cell growth and provides a biocompatible environment for human MDA-MB-231 cell lines. MWCNT-based nanostructured scaffolds were produced by plasma-enhanced chemical vapor deposition (PECVD) technique. MDA-MB-231 cells were seeded on MWCNTs-textured silicon scaffolds and on pristine silicon surfaces. After 1 week of culturing, the scaffolds were prepared for SEM analysis and immunocytochemical staining was performed for the two groups (MWCNT scaffold and pristine silicon surface), using MMP-2, MMP-9, PI3K, AKT and NF-κB primary antibodies...

Soft-tissue augmentation and implants are increasingly seen by the radiologist as more techniques emerge for a variety of indications and locations. Some surgical and implant procedures are performed for purely cosmetic reasons in otherwise healthy patients seeking to improve their body image, and some are performed for reconstruction after cancer or other chronic illnesses. Abdominoplasty, liposuction, and autologous fat grafting can be performed for abdominal and gluteal contouring. Injection of liquid injectable silicone has historically been fraught with legal issues, although it continues to be used for augmentation in a variety of anatomic locations...

Breast cancer is one of the most serious diseases, posing threats to women's physical and mental health. Gene therapy has been gradually regarded as an important part of tumor therapeutics. In the present study, the breast cancer‑specific gene 1‑small interference RNA (BCSG1‑siRNA) plasmid was designed, then encapsulated by chitosan‑silicon dioxide nanometer carriers. The results demonstrated a successful encapsulation of BCSG1‑siRNA in chitosan‑silicon dioxide nanoparticles (encapsulation efficiency exceeded 90%)...

Background: Breast implants can be characterized by their fill material, surface texture, or shape. Whereas long-term good quality studies have provided evidence for the fill material and texture, there is still little consensus for choosing the shape of an implant. Surveys indicate that many surgeons choose only one implant shape, for reasons that may not always agree with outcomes from long-term studies. Objectives: We reviewed the first author's experience over the last six years with both round and anatomical implants, compared the rate of complications with either implant shape, and discussed the importance of keeping an open mind about using both implant shapes for primary breast augmentation...

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare peripheral T cell lymphoma. BIA-ALCL is a disease of the fibrous capsule surrounding the implant and occurs in patients after both breast reconstruction and augmentation. More than 300 cases have been reported so far, including two in a transgender patient. Here we describe BIA-ALCL presented with a mass in a transgender patient and the first case of BIA-ALCL in the Czech Republic. In 2007, a 33-year-old transgender male to female underwent bilateral breast augmentation as a part of his transformation to female...

We describe an assembly-disposable microfluidic device based on a silicone-coated release polymer thin film. It consists of a disposable polymeric superstrate and a reusable functional substrate and they are assembled simply using vacuum pressure. The disposable polymeric superstrate is manufactured by bonding a silicone-coated release polymer thin film and a microstructured polydimethylsiloxane (PDMS) replica, containing only a simple structured microchannel. The reusable functional substrate generates an intricate energy field that can penetrate the micrometer-thick polymer film into the microchannel and control microfluids...
