Abstract
Aggressive fibromatosis is also known as desmoid tumor. They do not metastasize, but can cause significant morbidity though their local effects. We report a case of aggressive fibromatosis in a 44-year-old woman, who presented with a left-sided swelling in the neck. It was necessary to operate on her three times, which was followed by radiation therapy. Finally, decrease in the tumor size was achieved. The recommended treatment remains wide surgical excision when possible, with every attempt made to achieve a negative surgical margin. When a negative surgical margin cannot be achieved, as is often the case in the head and neck region, radiation therapy is recommended to prevent the high recurrence rates.
