INTRODUCTION:
Chondrosarcoma represent the most common type of malignant lesions of
the sternum[1]. Primary Bone lymphoma
(PBL) is a rare localization of invasion by Non-Hodgkin Lymphoma cells.
The most common histological type is represented by the Diffuse Large B
Cells Lymphoma (DLBCL). The sternum is an exceptional localization for
PB-DLBCL, accounting less than 1% of
cases[2].
We represent the case of a primary sternal DLBCL mimicking a sarcoma
with difficult assessment.
