Mild thrombocytosis secondary to iron-deficiency anemia and stroke.

A 45-year-old woman with mild thrombocytosis secondary to iron-deficiency anemia suffered from hemispheric infarction in absence of vascular, cardiac or coagulation pathologies. The modest raise of the platelets count seemed as the sole possible cause for the cerebral infarction. We wish to emphasize the inconstant benignity of mild non essential thrombocytosis at levels less than 1 million/cu.mm.
