[Severe aplastic anemia as a complication of treatment with metizol]

Aplastic anemia is the rare hematologic complication of the antithyroid medication. We present here the case of 39-years old female who was treated with Thiamazole due to Graves disease. This and the others cases cited in the literature indicate that antithyroid drugs-induced aplastic anemia is characterised by severe clinical status and profound marrow hypoplasia or aplasia but good prognosis with short term recovering.
