The authors concluded that TGFBR3 and MGEA5 rearrangements are much more common in hybrid HFTL-MIFS tumors than in classic MIFS, that HFLT and pure MIFS are unrelated, and that hybrid HFTL-MIFS tumors most likely represent HFLT with sarcomatous
progression rather than a neoplasm strictly related to MIFS.

Two malignant variants are known--first, the primary malignant GCT that was found in up to 10% of cases; and second, the rare sarcomatous
