ABSTRACT

Introduction: fibrosarcoma is a malignant soft tissue neoplasm which occurs most of the time in teenagers and young adults. Facial, and especially parotid gland localization, is very uncommon. Case report: A 44-year-old male patient, with no prior history, was hospitalized for swelling in the left parotid area noted 7 months before. The mass was painful and there was no facial paralysis. A CT scan revealed a tumoral process of mixed density in the left parotid gland. The thorax and abdominal CT scan was normal. The patient was initially treated by surgery and adjuvant radiotherapy. Discussion and Conclusion: Five percent of salivary gland primitive tumors are of mesenchymatous origin, 0.3 to 1.5% of which are sarcomas. Fibrosarcoma is an extremely rare mesenchymal malignant tumour. The diagnosis of parotid gland fibrosarcoma is confirmed by immunehistochemistry and cytogenetic tests. fibrosarcomas are rather uncommon in the salivary glands and have a high tendency towards recurrence. Surgery combined to radiotherapy seems to be the best treatment.
