Abstract
in English, Spanish

Thrombocytosis is usually a casual finding in children. Reactive or secondary thrombocytosis is the more common form, being the infections diseases the most prevalent cause of it. Regarding the number of platelets there are four degrees of thrombocytosis; in its extreme degree the number of platelets exceeds 1,000,000/mm(3). We describe a case of extreme reactive thrombocytosis in a healthy 6-year-old child. He required critical care admission for diagnosis and treatment (maximum number of platelets 7,283,000/mm(3)). We review the different causes of thrombocytosis in childhood, the differential diagnosis, and the available treatments in case of extreme thrombocytosis.

La trombocitosis es un hallazgo casual frecuente en pediatría. En niños, predominan las formas secundarias, siendo las infecciones su causa más prevalente. Se distinguen 4 grados de trombocitosis en función del número de plaquetas; en la forma extrema, se supera el 1.000.000/mm3. Se presenta un caso de trombocitosis extrema reactiva en un niño sano de 6 años, que requirió ingreso en cuidados intensivos para tratamiento y diagnóstico (cifra máxima de plaquetas de 7.283.000/mm3). Se revisan las diferentes causas de trombocitosis en la infancia, se describe el diagnóstico diferencial y se discute sobre los diferentes tratamientos disponibles ante un caso como el descrito.
