Altération de l’état général chez une patiente porteuse d’implants mammaires en polyéthylène depuis 1967. À propos d’un cas clinique exceptionnel

[Two cases of lymphoma in an implant capsule: A difficult diagnosis, an unknown pathology]

The anaplastic large cell lymphoma (ALCL) is a rare disease, its incidence in the United States is one case per 500,000 women and three for 100 million patients for breast single location. Forty-six cases have been reported in the literature. They can grow on any type of implant: expander prosthesis silicone and saline, smooth or textured envelope. Currently, the consensus process includes capsulectomy, removal of the implant, chemotherapy and radiotherapy. However, some authors classify under indolent disease, but we believe that some cases may escape any therapeutic and become very aggressive forms. It is therefore important to make an early diagnosis and start treatment urgently. Severity and suspicion of iatrogenic nature of ALCL have an obligation to inform future with implants.

What would surgeons like from materials scientists?

Surgery involves the repair, resection, replacement, or improvement of body parts and functions and in numerous ways, surgery should be considered human engineering. There are many areas in which surgical materials could be improved, but surgeons are generally unaware of materials available for use, while materials scientists do not know what surgeons require. This article will review some of the areas where surgeons and materials scientists have interacted in the past and will discuss some of the most pressing problems which remain to be solved. These include better implant materials for hernia repair, breast reconstruction, the treatment of diabetes, vascular stenting and reconstruction, and electrical pacing devices. The combination of tissue engineering and nanomaterials has great potential for application to nearly every aspect of surgery. Tissue engineering will allow cells or artificial organs to be grown for specific uses while nanotechnology will help to ensure maximal biocompatibility. Biosensors will be combined with improved electrodes and pacing devices to control impaired neurological functions.
