Rapid progression to cardiac tamponade in Erdheim-Chester disease despite treatment with interferon alpha.

[erdheim-chester disease]

Erdheim-Chester disease (ECD) is a rare form of non-Langerhans histiocytosis with heterogeneous clinical manifestations. The most common presentation is bone pains typically involving the long bones. Approximately 75% of the patients develop extraskeletal involvement. Cardiac involvement is seen in up to 45% of the patients, and although, pericardial involvement is the most common cardiac pathology of this rare disease, cardiac tamponade due to ECD has been very rarely reported. We describe a case of a patient found to have ECD with multi-organ involvement and small pericardial effusion, which progressed to cardiac tamponade despite treatment with interferon alpha.
