Abstract
Acromegaly patients have higher incidence of neoplasia than the general population, especially for colonic carcinoma. Recently, various hematological malignancies have been reported in patients with acromegaly. However, myelodysplastic syndrome has not been reported in acromegaly previously. In this paper, we reported a unique patient with acromegaly and concomitant pancytopenia and myelodysplastic syndrome.
