Primary cardiac low grade sarcomas mimicking myxomas. Pitfall in diagnosis
Cardiac sarcomas can resemble myxomas macroscopically and microscopically. These tumours can be easily misdiagnosed unless examined carefully. The presence of spindle cells with mitoses, hypercellular areas the formation of a cellular “cambium” layer beneath the surface and/or an unusual location of the tumour are often helpful in recognizing the true nature of these tumours.
