Collision tumor is a rare condition in which two neoplasms (usually benign and malignant), both growing in the same general area, collide with each other and become intermingled. We present histopathology and imaging correlation of xanthogranulomatous pyelonephritis coexistent with squamous cell carcinoma and osteogenic sarcoma of the kidney.
