Graves' disease with pancytopenia: A rare case report.

A variety of hematologic abnormalities can be seen in Graves' disease (GD), however; here, we describe a patient with GD and a very rare complication; pancytopenia.

Hence, in patients with pancytopenia and normal bone marrow examination, GD should also be considered.
