Synchronous Bony and Head and Neck Malignancies ? A Rare Presentation

The incidence of distant metastases in head and neck squamous cell carcinoma (HNSCC) is relatively small in comparison to other malignancies and the rate of development of a bony second primary in a patient with HNSCC even smaller. Presence of a second primary adversely impacts the survival and may significantly alter treatment planning . Pulmonary secondaries and second primaries are the most frequent in SCC. A bony second primary in HNSCC is rare and not reported. In this article, we report the case of a patient with oral cavity malignancy that developed osseous second synchronous primary to the distal end of the femur.
