Rhabdomyoblastic differentiation after chemotherapy in malignant triton tumor - a case-report

A case of malignant Triton tumor which consists of a malignant schwannoma accompanied by rhabdomyo-sarcomatous elements is reported. Only a small number is known in literature. The patient survived for four years without any sign of local recurrence or metastasis although an extremely poor prognosis for this neoplasm is reported. The therapy consisted of wide resection, irradiation and pre-and postoperative combination chemotherapy. The effect of multi-agent antineoplastic drugs on the differentiation of rhabdomyosarcoma cells and the relevant literature is discussed.
