Key result
Left atrial fibrous histiocytoma metastasis causes fatal severe mitral stenosis in a rare case.
Why the study?
Symptomatic mitral stenosis caused by a left atrial mass as the first sign of metastasis of a malignant tumor is extremely rare and frequently associated with poor prognosis.
Case Report (n=1)
A left atrial mass causing symptomatic mitral stenosis can be a rare presentation of metastasis from a malignant tumor.
Clinicians should consider metastatic sarcoma in left atrial masses causing mitral stenosis; extends reported cardiac sites but leaves optimal management open.
Symptomatic mitral stenosis caused by a left atrial mass as the first sign of metastasis of a malignant tumor is extremely rare and frequently associated with poor prognosis. We report a case of a 59-year-old man with a history of grade 3 malignant fibrous histiocytoma on his left tigh treated by limb-sparing surgery 17 months earlier, who was admitted with 10-days of worsening dyspnea. Imaging revealed a left atrial mass protruding through the mitral valve that resulted in severe mitral stenosis. Biopsy confirmed metastasis of malignant fibrous histiocytoma.

Auer et al. (2012) conducted a case report in Mitral stenosis (n=1). Metastasis of malignant fibrous histiocytoma was evaluated. A rare case of severe mitral stenosis caused by a left atrial metastasis of a malignant fibrous histiocytoma in a 59-year-old man, which resulted in sudden death four days after admission.
