A pathological fracture is one which occurs in diseased bone with trivial trauma or even without it. However, fracture occurring as a result of significant injury can masquerade underlying ominous bone pathology, which is highly likely to be missed in the garb of overwhelming traumatic aetiology. Pathological fracture as the manifestation of tumour in children less than 10 years of age is rare.1, 2 Fracture following significant trauma masquerading as underlying malignancy is even rarer. We report a case of 7-year-old male child, he had history of significant trauma with fracture shaft of femur, pathology was "missed" initially in the outset of trauma and on subsequent follow up it was found to be osteosarcoma.
