Background. Malignant triton tumor (MTT) is a relatively rare, aggressive tumor comprised of both malignant schwannoma cells and malignant rhabdomyoblasts. Because MTT frequently arises in the head and neck, the otolaryngologist must be aware of the nature of the tumor and its response to various tr

Abstract
Background.
Malignant triton tumors are rare neoplasias consisting of a malignant peripheral nerve sheath tumor with additional rhabdomyoblastic differentiation. These tumors are highly aggressive and prognosis is poor. Our aim is to describe the outcome and to identify potential prognostic factors.
Methods.
From 1993 to 2005, 7 patients with a malignant triton tumor of the head and neck were treated at our institution. A literature search revealed another 46 published cases. All these cases were analyzed for outcome and prognostic factors.
Results.
Patients with primary tumors involving the nose and paranasal sinuses have better, patients involving the neck a poor prognosis. All other locations show an intermediate course. Complete surgical removal is of crucial importance. Additional radiation or chemotherapy show little effect.
Conclusion.
Location of the primary tumor is a key factor for prognosis. Complete surgical removal is the only treatment associated with survival.Β© 2009 Wiley Periodicals, Inc. Head Neck, 2009

## h d i a Twenty-seven cases of malignant peripheral nerve sheath tumors involving the head and neck region over a period of 7 years were reviewed. They were graded from 1-3 based on necrosis, mitosis, cellularity, and pleomorphism. Mean age of occurrence was 42 years, with a range of 12-70 years
