Why the study?
Primary cardiac sarcoma is routinely misdiagnosed as atrial myxoma, presenting diagnostic challenges when evaluating recurrent primary cardiac tumors.
Primary cardiac sarcomas can be misdiagnosed as benign atrial myxomas, emphasizing the need for immunohistochemistry to accurately identify malignant variants upon recurrence.
No takes yet. Share an insight, caveat, or question.
Rare cardiac tumors and post-resection myxoma recurrence warrant extended surveillance; leaves open optimal prevention and follow-up protocols.
Kotasthane et al. (2025) studied this question.
