Polypoid tumour of the pericardium--a previously unrecognised macroscopic appearance of metastatic bladder carcinoma.
We report a case in which a metastasis to the pericardium from a bladder carcinoma had a polypoid appearance similar to that of the primary tumour. We suggest that the local environment of a metastatic deposit may influence its macroscopic appearance. The case described emphasises the importance of thorough exploration of the pericardial sac at surgery.
