Appendicular metastatic prostate cancer simulating osteosarcoma, Paget's disease, and Paget's sarcoma.
Skeletal metastases from prostate cancer is common and usually do not pose a diagnostic dilemma. This study reviews radiographic appearances of prostatic metastases to the appendicular skeleton in four patients where the appearances simulated osteosarcoma, Paget's disease and Paget's sarcoma. Prostatic metastases to long bones can produce appearances considered characteristic of other lesions and suggest misleading alternative diagnoses.
