Lung cancer is known to have a high metastatic potential for the brain, bones, adrenal glands, lungs, and liver. Orthopaedic manifestations frequently include bony metastasis commonly to the vertebrae. Olecranon is less known for skeletal metastasis and its involvement as the primary site is least known in literature. We present a case of a 60 year old male who presented with lytic lesion at olecranon and turned out to be a secondary lesion with biopsy showing adenocarcinoma. Patient was evaluated further and primary lung cancer was diagnosed.
