Myelofibrosis and benzene exposure.

Petrol station attendants are exposed to benzene, a well-known carcinogen for blood malignancies. A case of myelofibrosis in a petrol station attendant is presented, along with other reports of myelofibrosis after benzene exposure obtained from the Swedish Cancer Environment Register. Findings of an increased risk for myelofibrosis in the transport sector also suggest a causal relationship with benzene.
