Case Discussion
Aggressive fibromatosis is a benign fibrous neoplasm arising from fascia, periosteum and musculoaponeurotic structures of the body with no metastatic potential resulting from the abnormal infiltrating proliferation of fibroblasts. In the head and neck region, fibromatosis tends to be locally aggressive and to invade bone and soft tissue structures. Three types of these tumors can be distinguished: intra-abdominal form, the form of the abdominal wall, and extra-abdominal form. Histologically, desmoids are characterized by the proliferation of uniform spindle cells resembling myofibroblasts, in a background of abundant collagenous stroma and vascular network.
