Chronic myeloid leukemia (CML) is characterized by increased and unregulated proliferation of granulocytic lineage in the bone marrow and
presence of these immature myeloid cells in the peripheral blood with presence of Philadelphia (Ph) chromosome. Tyrosine kinase inhibitors
are the most important drugs in the CML therapy and provide long disease-free survival. Due to the increased survival of CML patients with
continual administration of these drugs, the chance of development of secondary malignancies may increase. The most common secondary
malignancies are prostate, colorectal and lung cancer, non-Hodgkin lymphoma, malignant melanoma, non-melanoma skin tumors and breast
cancer. Herein, we are describing a rare case of Hodgkin lymphoma in a patient of CML after ten year of primary disease presentation. Hodgkin
lymphoma in a known case of CML is very rare and further studies are also needed to know the pathogenic relationship between the two entities
and to assess the risk of secondary Hodgkin lymphoma in CML patients treated with tyrosine kinase inhibitors. CML itself is a risk factor for
development of solid cancers and hematologic malignancies. In addition, patients on chemotherapy are immune-compromised and may be at
greater risk of neoplasm driven by infectious agents such as Epstein-Barr virus.
