Composite follicular lymphoma and classic Hodgkin lymphoma

Abstract

Composite lymphoma is very rare and a combination of Hodgkin lymphoma and non-Hodgkin lymphoma and even histiocytic tumors can occur. Because of the unfamiliarity, not only can this cause diagnostic problems, but can also affect treatment plan. We report a case of composite lymphoma in a 40-year-old male. Initial biopsy showed a composite lymphoma of follicular lymphoma grade 1 and classic Hodgkin lymphoma. After chemotherapy, another lymph node was taken because of disease progression, which revealed follicular lymphoma, grade 3a without Hodgkin lymphoma component.
