Malignant triton tumor (MTT) of the neck.
Malignant Triton Tumor (MTT) is a rare, malignant periphere nerve sheath tumor with rhabdomyoblastic differentiation. One third of described MTT's were located at the head and neck region. One third of these are associated with neurofibromatosis type 1. MTT most often appears in the third decade. MTT's are very aggressive tumors with early metastases and the overall survival is poor (26%). Therefore, early diagnosis and correct treatment is of utmost importance. We report a case of MTT of the left supraclavicular region in a 41-year-old man. We present the pathological findings, both light and immunohistochemically.
