title: A guide to oncological management of soft tissue tumours of the abdominal wall.
abstract: BACKGROUND
  An abdominal mass is a common clinical presentation, and a small percentage of such patients will have an abdominal wall tumour with the two most common pathologies being fibromatosis and soft tissue sarcoma.
  
  
  METHODS
  Here we present the available literature on the diagnosis and management of both fibromatosis and soft tissue sarcoma, in the context of our experience in a tertiary referral centre for sarcoma.
  
  
  CONCLUSIONS
  Appropriate cross-sectional imaging and a pre-operative tissue diagnosis by percutaneous core biopsy are necessary to define management. Desmoid fibromatosis can be managed initially by observation with serial imaging, with surgery being reserved for those patients who demonstrate progression. Soft tissue sarcoma can display a range of pathologies from relatively indolent tumours to locally aggressive sarcomas that can readily metastasise. An accurate pre-operative histological diagnosis and staging enables a multidisciplinary approach to management. This may include chemotherapy and radiotherapy, but the mainstay of treatment remains wide surgical resection and abdominal wall reconstruction. Patient outcomes are worse if referral is delayed or if the sarcoma is incompletely resected without an initial tissue diagnosis.
