title: [Carcinoma in a 40-year chronic oro-antral communication].
abstract: A squamous cell carcinoma developed in a 66 year old patient in the region of a traumatically caused oro-antral fistula that has persisted for 40 years. The clinical course and histological findings are presented. Based on the few case reports in the literature the occurrence of malignancies in chronic traumatic fistulae is discussed. Reference is also made to causal relationships between such a fistula and malignancy under the aspect of forensic medical consultations.
