Successful Management of Aggressive Fibromatosis of the Neck: A Case Report

Background: Aggressive fibromatoses are histologically benign fibrous neoplasms originating from musculoaponeurotic structures throughout the body. They are locally invasive and erode adjacent vital structures. The head and neck region constitutes 7-25% of all extra-abdominal cases.

Case Report: Here, we report the case of a patient with aggressive fibromatosis in the left side of the neck. While the tumor deeply invaded the scalene muscles, the lesion was successfully treated by surgery followed by radiotherapy. The patient has been disease free for the last 7 years following treatment.

Conclusion: Due to its unusual location in the head and neck region, aggressive fibromatosis should be considered in the differential diagnosis of invading lesions of the neck.
