RT Journal Article SR Electronic T1 Essential thrombocythemia in a child. Diagnostic and therapeutic dilemma JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 1806 OP 1808 VO 26 IS 11 A1 Asghar, Ramyar A1 Behzad, Elahi A1 Mohammad, Golsorkhtabar-Amiri YR 2005 UL http://smj.org.sa/content/26/11/1806.abstract AB We report an 11-year-old child with essential thrombocythemia ET, a very rare myeloproliferative disorder among children. Essential thrombocythemia can be complicated by life-threatening thrombosis with a risk of converting into acute leukemia. Cytoreductive therapy may reduce the risk of thromboembolic complications. We usually recommend cytoreductive treatment for asymptomatic adult patients with platelet counts of more than 1.5 million/micro liter, but treatment remains obscure in children. Herein, we report the results of child with ET, treated successfully with hydroxuea.
