Squamous cell carcinoma of the pericardium found during coronary bypass surgery of possible cutaneous origin.

Metastatic neoplasms of the pericardium are more common than primary tumors. Isolated metastasis of cutaneous squamous cell carcinoma to the pericardium has not been described. We report a case of squamous cell carcinoma of the pericardium diagnosed after coronary bypass surgery without any primary tumor. The only significant history is the removal of multiple "skin cancers" in the past.
