Aetiology
Benign fibrohistiocytic tumours of the retroperitoneum or peritoneum (BFTRP) are rare and typically occur in adults between the ages of 40 and 60 years. The exact cause of these tumours is unknown, but they are thought to arise from mesenchymal cells in the lining of the abdominal cavity.
Diagnosis
Diagnosis of BFTRP is typically made by imaging studies such as computerized tomography (CT) and magnetic resonance imaging (MRI). In some cases, a biopsy may be needed to confirm the diagnosis.
Differential diagnosis
Differential diagnoses for BFTRP include other benign tumours such as lipomas, cysts, and leiomyomas, as well as malignant tumours such as sarcomas.
Treatment
Treatment of BFTRP typically involves surgical resection, followed by chemotherapy and/or radiation therapy if necessary.
Prognosis
The prognosis for BFTRP is generally good, with most patients achieving a complete recovery. In some cases, however, the tumour may recur and further treatment may be required.
