[Triton's tumor in children: a report of two cases]

Triton's tumor is a rare neoplasm, consisting of both neurogenic and rhabdomyoblastic components. Triton's tumor does not respond well to chemo- or radiotherapy, resulting in its poor therapy effects. This paper reports on two cases of this malignancy diagnosed in our department. The first one was treated with CWS chemotherapy followed by radical tumor resection, which resulted in 4.5 year complete remission. The other patient was treated with chemotherapy according to CWS protocol, achieving partial regression of the tumor. We suggest that this response may be connected with the sensitivity of the RMS embryonal component of the tumor to chemotherapy. This partial remission may create a possibility of radical tumor resection.
