[Laryngeal cancer following gunshot injury and paraffin injection]

Subcutaneous and submucosal injections of paraffin were a wide-spread technique in plastic and reconstructive surgery during the early decades of this century. Intralaryngeal injections were applied to patients suffering from paralysis of one vocal cord or a defect resulting from perforating trauma, intending improvement of the voice. This method was widely abandoned within the fifties when severe complications like foreign-body granuloma and carcinoma developed in patients undergoing paraffin injections. The development of cancer after a trauma is a common question in expert reports. We report the case of a patient who developed carcinoma of the vocal cord 49 years after perforation of the larynx by a shot with consecutive injection of paraffin. The relationship between trauma, injections of paraffin and cancer is discussed and consequences on diagnostics and treatment of risk patients are outlined.
