Abstract
This paper describes a rare case of malignant triton tumor (MTT), a malignant peripheral nerve sheath tumor with rhabdomyoblastic differentiation, that occurred in a 21-year-old male with no concomitant clinical signs of neurofibromatosis. Although total surgical excision is ideal, the high recurrence rate and distant metastases frequently result in a poor prognosis. A biopsy, in this case, revealed spindle cells organized in short fascicles, with minor anisonucleosis and cross-striations indicating rhabdomyomatous differentiation. Positive immunohistochemistry for epithelial membrane antigen (EMA), Desmin, and S100 markers validated the diagnosis. For further treatment, the patient was referred to a cancer center. Even without clinical signs of neurofibromatosis type 1 (NF-1), the research emphasizes the need to evaluate MTTs as a differential diagnosis for individuals presenting with tumors in the head and neck area. Histopathology and immunohistochemistry are useful diagnostic techniques, and early intervention with surgical excision may enhance the outcome. The paper concludes with a review of the histological criteria needed to establish the diagnosis of MTT and the distinctions between sporadic and NF-1-associated tumors.
