Giant clear cell renal carcinoma extended from the kidney until the pulmonary artery

Duringthe 13th stage of the 1967 Tour de France, near the summit of Mount Ventoux, race leader Tom Simpson fell dramatically from his cycle. Legend dictates that Simpson demanded in whispered gasps 'Put me back on my bike!' just moments before succumbing to a fatal cardiac arrest. Although post-mortem examination revealed amphetamines in Simpson's body, the story bears testament not only to the fanatical devotion of many endurance athletes, but also to the gruelling nature of this 3500 km event. Riders completing the Tour are estimated to have scaled the combined equivalent of Ben Nevis, Scafell Pike, Snowdon, Mont Blanc, Kilimanjaro, and Everest within 21 days. In 2013, the year that has witnessed the 100th excursion of the Tour, the risk-benefit ratio of such extreme exercise continues to provoke fierce controversy amongst the scientific community.
