Malignant triton tumour of the parapharyngeal space: A case arising from the cervical sympathetic nerve

Abstract

Background: Malignant triton tumour is a relatively rare, aggressive sarcoma comprising both malignant schwannoma cells and malignant rhabdomyoblasts. Malignant triton tumour of the parapharyngeal space is exceptionally rare, with only one case being described in the literature. Malignant triton tumour of the cervical sympathetic nerve has not previously been reported. Methods: We report a case involving the parapharyngeal space and arising from the cervical sympathetic nerve, and we review the management and outcome of the previous case reported in this rare location. Conclusions: The parapharyngeal space is a unique location. Owing to this specific localisation, adjuvant therapy in addition to complete resection may be important in the treatment of malignant triton tumour in this rare location. © 2007 JLO (1984) Limited.
