Primary sarcomas of the salivary glands occur rarely with few cases having been reported. Fibrosarcoma is a rare type of primary sarcoma with a poor prognosis and low life expectancy. Microscopically, these tumors resemble their counterparts encountered in other areas. They can be easily confused with spindle cell (sarcomatoid) carcinomas, myoepithelial carcinomas or malignant melanomas. We present an unusual case of a primary fibrosarcoma that arose in the right parotid gland of a 50 years male, who presented with a large nodular mass in the right preauricular region. Computed tomography (CT) scan revealed a tumor arising from the right parotid gland. A near total parotidectomy was performed and the histopathology report showed neoplastic spindle cells predominantly arranged in a ‘herring bone’ pattern. On immunohistochemistry, the tumor was positive for vimentin and was negative for pancytokeratin and S-100, which lead to a firm diagnosis of fibrosarcoma.
