Malignant triton tumor (MTT) is a rare and devastating malignant peripheral nerve-sheath tumor, which shows rapid growth and poor clinical outcomes. Here, we reported a 2-year-old girl who was diagnosed as MTT, an overview of the literature was conducted to discuss the clinical features and optimal treatment strategies of MTT. Methods: We conducted an analysis of 42 patients from the PubMed, Medline, Embase and Web of Science databases for relevant articles published between 1938 and 2018. Results: A 2-year-old girl died of tumor recurrence. Forty-two eligible cases of MTT in children (birth to 18 years; mean age, 8.3 years), the highest frequency of occurrence was in 12-16 years; and the male-to-female ratio was 1.7:1. Only 33 provided complete treatment details: 11 patients received treatment by surgery alone; 2 received both surgery and chemotherapy; 4 received both surgery and radiation therapy; 14 received surgery, chemotherapy, and radiation therapy; 1 case received chemotherapy and radiation therapy; and only 1 received supportive care. In the 33 cases, the average OS and 5-year OS probability were 23.9 months (range, 0.3-156 months) and 27.5 ± 4.3%. There were significant differences between radiation therapy and patient survival (p<0.05), postoperative chemotherapy/radiation therapy and patient prognosis (p<0.05). Conclusion: The clinical and histopathological features and therapeutic options for MTT are discussed in the light of published data. Further studies are needed to improve survival in children with this rare malignant tumor.

“…We compiled data on reported cases of MTT in the recent 6 years (2018–2023, Table 1). 1,6–38 There were totally 37 cases with a mean age of 39.4 years (range 8 months old–75 years old), including 24 male and 13 female patients. Eleven cases originated in the abdomen (30%), 10 cases in the head and neck (27%), 8 cases in the thoracic cavity (21%), 6 cases in the limbs (16%), 1 case in the spine (3%), and 1 case in the buttocks (3%).…”

Malignant triton tumor (MTT) is a highly aggressive malignant neoplasm, classified as a variant of malignant peripheral nerve sheath tumor with rhabdomyoblastic differentiation. There are few reports that MTT occurred in urogenital system. In the present study, we report the first MTT occurring in the uterus. A 57‐year‐old woman came to the emergency department due to persistent vaginal bleeding for 2 months. The gynecological palpation found that a club‐shaped excrescence existed in the vagina about 7 cm × 3 cm × 3 cm. The mass located in the lower segment of the uterus and the cervix was confirmed by gynecological vaginal ultrasound and magnetic resonance imaging, which was preliminarily diagnosed as cervical carcinoma. After neoplasm punch biopsy, the pathological diagnosis was malignant triton tumor. The patient finally lost follow‐up. This is the first report about MTT in the uterus and suggests that pathological biopsy combined with imaging examination is necessary for the diagnosis of rarely MTT.

“…Although most MTT cases are diagnosed in patients under 35 years of age, few cases have been reported in children and adolescents (9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19). Main series have shown no gender predilection and, although widely distributed, the head, neck and trunk have been described as the most common locations.…”

Malignant triton tumor (MTT) is a very infrequent variant of the malignant peripheral nerve sheath tumor (MPNST) with rhabdomyoblastic differentiation. Up to 70% of cases are diagnosed in patients with neurofibromatosis type 1 (NF1). It is a highly aggressive pathology with early relapses occurring in up to 50% of patients. Despite multimodal treatment the prognosis is poor, with long term survival rates not exceeding 15%. We present the case of an adolescent male with known NF1 diagnosed with an aggressive retroperitoneal MTT and disseminated pulmonary disease.
