Reactive thrombocytosis (secondary thrombocytosis) is frequent and typically moderate. We report a case of extreme thrombocytosis and leukocytosis secondary to an iron deficiency anemia. A 21-year-old woman is admitted in emergency department for acute headache. Biological assessment reveals a severe microcytic anaemia (5.4 g/dL) with thrombocytosis (2500 giga/L) and leukocytosis (35 giga/L) leading to multiple diagnosis hypotheses. Finally, biological evaluation concludes to a diagnosis of iron deficiency anaemia related to insufficient oral intake and menorrhagia. Reactive hyperleukocytosis and thrombocytosis rapidly resolved with iron supplementation. This case is a reminder that iron deficiency-related thrombocytosis can sometimes be severe. However, the associated reactive leukocytosis is quite exceptional.
