A second primary intestinal-type adenocarcinoma of the sinonasal tract induced by wood dust

Intestinal type adenocarcinoma of the sinonasal tract is associated with exposure to wood dust. We report the case of an adenocarcinoma tumor of the left sinonasal area diagnosed in 1998. Nineteen years earlier (1979), an intestinal type adenocarcinoma of the right nasal cavity was diagnosed. The first tumor was treated in 1979 surgically followed by postoperative radiotherapy. The second tumor showed the same histological features as an intestinal type adenocarcinoma (papillary type). The patient had a history of a 10 year exposure to wood dust (furniture worker), and the latency time of this patient was 48 years in 1998. We suppose that the tumor of the left side is a second primary intestinal type adenocarcinoma. This case indicates the usefulness of a lifelong follow up of patients with adenocarcinoma of the nose because of the wide range of latency times of these tumors.
