A 72 year old woman presented with left hip pain. Computed tomography showed bony metastasis of the femoral neck. There was no obvious primary source. A total hip replacement was carried out and histology from the femoral neck showed highly pleomorphic tumour cells consistent with metastatic malignant melanoma. A malignant melanoma (Clark’s level 3, Breslow thickness 1.9 mm) had been excised from her posterior right thigh two years earlier. Lung, prostate, thyroid, kidney, and breast cancer are the most common sources of bony metastases, with rarer causes including bowel and bladder cancer and malignant melanoma.
