title: [Ackerman's tumor of the larynx and occupational exposure to asbestos].
abstract: The so-called "Ackerman's tumor" is a neoplasm of uncertain dignity. Aim of this paper is to clarify, whether this is an asbestos-induced tumor of the larynx in accordance with German regulations for occupational diseases. A 43-year old male presented the clinical picture of a stenosing laryngeal tumor. A verrucous neoplasm without a proven malignity in the sense of an Ackerman's tumor was diagnosed through several sequential biopsies. Approximately 2 years later a total laryngectomy was performed, because of a squamous cell carcinoma of the larynx. An occupational disease in accordance with 4104 BKV was claimed in connection with an asbestos exposition of 28,3 fibre years (fibres/m3 x years). An Ackerman's tumor is--in accordance with its definition in the German-speaking area--not conclusively malignant, there is no indication of a relation between asbestos and such a tumor in literature, there is no specific benign disorder of the larynx caused by asbestos. This brings us to the conclusion that the Ackerman's tumor of the larynx is no asbestos-induced laryngeal tumor as per German occupational disease regulations.
