Aggressive fibromatosis versus low grade fibrosarcoma - a diagnostic dilemma

ABSTRACT

The fibromatosis are a group of lesions that can infiltrate widely, replacing muscle, fat and bone with fibrous tissue of varying cellularity. They do not develop distant metastases, however, locally they show an aggressive and infiltrative behaviour. The major challenge in the diagnosis lies in not over or under diagnose of fibrosarcoma and an underdiagnosis of reactive fibrosis. But this histologic differentiation is necessary owing to different treatment strategies
