Cardiac metastases are among the topics with limited systematic reviews. Theoretically, the heart can be infiltrated by any malignancy with the ability to spread to distant structures. Thus far, no specific tumors are known to have a predilection for the heart, but some do metastasize more often than others, for example, melanoma and primary mediastinal tumors. We report a case of cardiac metastasis from a diffuse large B cell lymphoma in a young man. The peculiarity of this case is that besides the involvement of right ventricle and atrium, the tricuspid valve was also infiltrated. Valvular metastasis is rarely reported in the medical literature.
Core tip: This manuscript describes a case of diffuse large B-cell lymphoma involving the heart, in particular affecting the tricuspid valve. The clinical features in this case are clearly illustrated. The peculiarity of this case report is that besides the involvement of the right ventricle and atrium, the tricuspid valve was also infiltrated. Secondary valvular metastasis is unusual and the patient remained in remission after a course of chemotherapy.
