Renal carcinoma presenting as cardiac tamponade: a case report and review of literature.

Pericardial involvement in an advanced malignancy is common but malignancy presenting as cardiac tamponade is rather uncommon. Review of English literature using Medline CD ROM revealed 131 cases since 1935, who have presented with this life threatening emergency. Lung is the most common primary site followed by lymphomas and leukemias. We report a case of transitional cell carcinoma of kidney presenting as cardiac tamponade. Such a presentation of transitional cell carcinoma of kidney has never been reported.
