Abstract:
We report a case of malignant mesenchymoma developed in the mesentery in a 62-year-old man with no past history. It was an huge mass in the mesentery of the ileum. The tumor was composed of areas of chondrosarcoma and rhabdomyosarcoma in addition to an undifferentiated fusiform component. Malignant mesenchymoma is a rare sarcoma occurring preferentially in the retroperitoneum or the thigh. The location in the mesentery is exceptional. Malignant mesenchymoma is discussed more particularly with dedifferentiated liposarcoma with heterologous elements. The patient is alive without recurrence three years after surgery.

The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
