Hematological malignancies are very rare in acromegaly. Here, we report an 80-yearold patient with acromegaly and multiple myeloma. Patient died within a month of diagnosis. Previous studies have shown that growth hormone and somatomedin-C activate B lymphocyte and somatomedin-C receptors are found in multiple myeloma cells. Possible effects of growth hormone and somatomedin-C on multiple myeloma progression are discussed in the light of the relevant literature.eninfo:eu-repo/semantics/closedAccessAcromegalyMultiple MyelomaArticle173N/AQ47577WOS:000217336100007
