Primary lymphoma of the bone is a rare malignancy accounting for 3% to 7% of all primary bone malignancies. Commonly seen in elderly population, very rarely also seen in pediatric population as well. Lymphoblastic variant of Non-Hodgkin’s lymphoma being an aggressive entity has a very rapid course. Being a radiological masquerader and a rare entity it has to be differentiated from its mimickers. Here we present a case of 6-year-old female child who had progressive swelling of left thigh following multiple episodes of trivial trauma who was radiologically diagnosed as Ewings/osteogenic sarcoma. However, histopathology and immunohistochemistry studies were s/o T-cell lymphoblastic Non-Hodgkin’s Lymphoma.
