Tibial metastasis from muscle invasive bladder carcinoma: an unusual site

We report a case of a 61-year-old gentleman who presented with frank hematuria with associated weight loss and on-going left knee pain. Subsequent investigation revealed a muscle invasive bladder carcinoma with a related unusual bone metastasis. Though bone metastases form bladder carcinoma are common, frequent deposition sites include the spinal column and pelvis. This case report is to the best of our knowledge the first reported case of a tibial metastasis for relevant bladder carcinoma. Furthermore, we reviewed the literature, relevant diagnostic and management surrounding such occurrences.
