Introduction:Malignant peripheral nerve sheath tumors (MPNSTs) are very rare. Malignant triton tumor is an aggressive variety of MPNSTs with rhabdomyoblastic differentiation. In this study we reported the clinical, radiographic, histopathologic and immunohistochemical features of an intramandibular malignant triton tumor.
Case Report: The patient was a 31 year-old male who was referred to maxillofacial surgery ward of Mashhad dental school with a painful swelling in the anterior part of mandible and facial asymmetry. After histopathological evaluation, surgery was performed and immunohistochemical staining confirmed the diagnosis of Triton tumor. Patient was referred for further necessary treatments.
Conclusion: In cases of mandibular tumors with initial histopathologic findings of sarcoma, uncommon differential diagnosis such as peripheral nerve sheath tumors must be considered as well.
