Abstract

The coexistence of different malignant diseases in the same patient is an entity that can rarely be encountered clinically. This can be observed as the presentation of two distinct types of cancer in the same patient simultaneously or at different times. The genetic structure of the individual, environmental factors and chemotherapeutic agents and radiotherapy used in the treatment of primary disease may play a role in this process. Hodgkin lymphoma is hardly ever observed after non-Hodgkin lymphoma treatment. In this report, we aimed to share two cases that were diagnosed with classical Hodgkin lymphoma in their follow-up after non-Hodgkin lymphoma diagnosis and treatment in our clinic.
