Lymphoma Heterogeneity: Three Different Histological Pictures and One Unique Clone

Abstract EN

We report a patient who developed up to three different lymphomas with the same clonal IGH rearrangement.

She was first diagnosed of splenic zone marginal lymphoma and relapsed for the first time with Hodgkin lymphoma histology and later with diffuse large B-cell lymphoma histology.

Subsequent biopsies and analysis of clonally rearranged IGH genes helped to elucidate the clonal relationship between the three histologies and to confirm a common origin from the three tissue histologies.

An integrated diagnosis should always be performed in order to achieve the most accurate diagnosis and be able to choose the best therapeutic options for our patients.
