Mentzel et al. [16] further demonstrated the coexpression of SMA and CD34 in 6 mGTs, underlining that this immunophenotype could complicate the differential diagnosis with other CD34-positive tumors, such as myopericytoma or solitary fibrous tumor (SFT), particularly in the presence of myxoid stroma. The gene discussed is SMN1; the disease is solitary fibrous tumor.
