Neoplasms of the abdominal wall

Neoplasms of the abdominal wall

As the abdominal wall is composed of muscle, fascia and bone, benign and malignant tumours can arise from each, although these are rare. This is usually considered by pathologists to be a hamartoma and is more common in women. Some, however, believe it to be a fibroma and possibly the result of repeated trauma. Desmoids also occur in familial adenomatous polyposis. Histologically , they contain plasmodial cell masses resembling giant cells. They undergo central myxomatous change. Surgical excision with a wide margin is required to prevent local recurrence, which is a frequent problem.
