Abstract
We describe the case of a 70yearold male with acromegaly who developed colon carcinoma and myelodysplastic syndrome MDS during the course of acromegaly MDS progressed to acute myeloid leukemia but was refractory to chemotherapy Acromegaly is a rare disorder caused by excessive amounts of growth hormone GH primarily secreted by pituitary adenomas Patients with acromegaly are more prone to develop various malignancies but there are few reports of hematological malignancies in such patients In the present case excessive endogenous GH and insulinlike growth factorI levels may have altered cell proliferation and thereby affected the oncogenesis and chemosensitivity of both malignancies
