title: [Simulation of malignant tumors by undeclared polyvinylpyrrolidone in drugs].
abstract: Numerous drugs are available containing polyvinylpyrrolidone as a carrier and retard substance. Repeated intramuscular or subcutaneous injections of polyvinylpyrrolidone over a long time can lead to tumor-like foreign body reactions mimicking true malignant tumors by clinical and histological features. Additionally, a storage of polyvinylpyrrolidone in visceral organs is possible in such patients.
