The evaluation of 40 patients with adenocarcinoma of the nasal cavity shows that these patients had been exposed to oak and beech dusts proving the causal connection between this type of wood dust and adenocarcinoma of the nose. In view of this knowledge, compensation in accordance with section 551 (2) RVO (Reichsversicherungsordnung: social insurance statute) can be recommended in individual cases after intensive occupational exposure to oak or beech dust over many years.
