Epicardial mass causing cardiac compression: an unusual involvement in lymphomatoid granulomatosis.

Lymphomatoid granulomatosis is a rare, diffuse, large B-cell lymphoma that is positive for Epstein-Barr virus. A multiorgan process, it manifests itself chiefly in the lungs but can also affect the skin, nervous system, and kidneys. Cardiac involvement and pericardial effusion are very unusual. We report the case of a 62-year-old man with lymphomatoid granulomatosis involving the heart and lungs. Diagnosis was confirmed with wedge biopsy at pericardiotomy, and the patient was treated with cyclophosphamide, prednisolone, and vincristine. Although the patient was still symptomatic at 6-month follow-up, he was in partial remission with improved functional capacity.
