Long-term Survival of a Patient with Malignant Lymphoma of Bone

Malignant lymphoma of bone is an uncommon tumour. A number of studies have outlined the clinicopathological findings and overall favourable prognosis in adults. We report on a woman whose tumour was originally diagnosed as a secondary carcinoma of the upper femur. Twenty-three years later following proximal femoral replacement, the original histology was reviewed using immunohistochemical techniques and revised to B-cell malignant lymphoma of bone.
