Lytic Bone Metastasis in a Case with Primary Breast Lymphoma

摘要

Bone metastasis alone without involvement of bone marrow is rarely seen in primary breast lymphoma (PBL). It has a poor prognosis. A 64-years old woman was diagnosed as high-grade PBL T type. The patient received 6 sessions of chemotherapy with a diagnosis of stage IIAE PBL. The patient achieved remission and was followed for 12 years. She underwent surgery due to fracture at lower half of right femur. Palliative radiotherapy (30 Gy) was given to right femur. Here, we presented a patient with high-grade PBL T type developed lytic bone metastasis without bone marrow involvement.
