Fibromatosis is a histologically benign fibrous neoplasm that arises from the musculoaponeurotic tissues of the body. It is microscopically benign but it can be locally invasive with a tendency to also recur locally after resection. We experienced a case of a fibromatosis occurring in the parapharyngeal space. A 73-year-old female with a low grade performance status (PS) presented at our department with a right neck mass. The MRI findings demonstrated a well-enhanced tumor lesion within the left parapharyngeal space. Histological examinations indicated the tumor to be fibromatosis. Due to her low grade PS, we did not perform surgical treatment. First, the patient received steroid pulse therapy to treat the parapharyngeal lesion. Despite administeringth e steroidt herapy, the tumor increasedi n size, and she complainedo f severep ain. Therefore, we planned to perform external irradiation as a palliative therapy. As a result, a partial response was achieved with a relief of the severe pain from the tumor. The tumor has not increased in size after the radiation therapy.
