Aggressive Fibromatosis of Head and Neck in a Child

摘要

Aggressive fibromatosis is a broad group of benign fibrous tissue proliferations of similar microscopic appearance that are intermediate in their biological behavior between benign fibrous tissues and fibrosarcomas. They are rare lesions accounting for less than 3 % of all soft tissue tumours. Usual site is extremity whereas head and neck fibromatosis is a rare occurrence. We present a case of aggressive fibromatosis of the infratemporal fossa in a child, which was treated by surgical excision with adjuvant hormonal therapy.
