[Occupational and environmental risk factors for essential thrombocythemia: a case-control study].

Background: Essential Thrombocythemia (ET) is a chronic myeloproliferative disorder characterized by a long median survival, even though serious complications such as acute hemorrhagic or thrombotic events are not infrequent. Very few information are available about risk factors for ET because of lack of epidemiological studies focused on this topic.

Methods: We conducted a case-control study in order to analyze the possible association between ET and some occupational and environmental risk factors.
