Two rare complications of chronic benzene poisoning: myeloid metaplasia and paroxysmal nocturnal hemoglobinuria. Report of two cases.
Two patients, one with myeloid metaplasia and the other one with PNH, both due to chronic exposure to benzene are presented. The patient with PNH exhibited also marked monocytosis as a rare hematologic finding of chronic benzene exposure. The etiological relationship between myeloid metaplasia, PNH and chronic benzene exposure is discussed.
