Abstract
In addition to anaplastic large T-cell lymphomas (BIA-ALCL), other implant-related
tumors have been described for some years. Squamous cell carcinoma (SSC) and B-cell
lymphomas occurred in
very rare cases. The unexplained pathogenesis as well as the unclear individual risk
profile is an ongoing source of uncertainty for patients and physicians. The pathogenesis
of the tumors
is still largely not understood. While BIA-ALCL occurs more frequently with textured
breast implants, other tumors were also observed with smooth implants and at other
implant sites.
Multiple potential mechanisms are discussed. It is suspected that the etiology of
a chronic inflammatory response and subsequently immunostimulation is multifactorial
and appears to play a
key role in the malignant transformation. Since there are currently no sufficiently
valid data for a specific risk assessment, this must be done with caution. This article
presents the
incidence, pathogenesis, as well as the level of evidence according to the current
state of knowledge, and evaluates and discusses the current literature.
