Non-Hodgkin’s disease is a type of lymphoma and accounts for approximately 1% of all cancers. It spreads contiguously and along lymphatic pathways. Non-Hodgkin’s disease is usually confined to the lymph nodes, although uncommon may be found in any organ system, either as a primary manifestation or as dissemination of systemic disease. Extra nodal disease is commoner in children and in the immunocompromised host. Primary Non-Hodgkin's disease of bone (Reticulum cell sarcoma) is a rare, extra nodal lymphoma histologically identical with those arising in lymphoid tissue but presenting initially as a localized solitary bone lesion accounting for approximately 3% of malignant bone tumours. The metadiaphyses of long bones are most commonly involved, particularly the femur, tibia and humerus. Flat bones are also involved, especially the ilium and scapula. We report a rare case of non-Hodgkin’s lymphoma with bony metastasis showing aggressive periosteal reaction.
