Massive myocardial infiltration by primary anaplastic T-cell lymphoma: a case report.

Primary cardiac lymphoma is not frequent, and the lack of specific symptoms makes the diagnosis extremely challenging and often limited to autopsy findings. Our case highlights the importance of an appropriate diagnostic algorithm, requiring non-invasive multimodality assessment imaging and then invasive cardiac biopsy. This approach may allow an early diagnosis and an adequate therapy for this otherwise fatal pathology.
