The exact cause of benign fibrohistiocytic tumours is unknown, but it is believed to be related to a combination of genetic and environmental factors.
Benign fibrohistiocytic tumours are usually diagnosed based on clinical presentation, imaging studies and histopathological examination. Imaging studies such as MRI or CT scan may be used to identify the size and location of the tumour. Histopathological examination of a biopsy specimen is then performed to confirm the diagnosis.
The differential diagnosis for benign fibrohistiocytic tumour includes other benign and malignant soft tissue tumours.
Treatment of benign fibrohistiocytic tumours is typically surgical excision. However, radiotherapy may be used if the tumour is in an area that is difficult to access surgically.
The prognosis for benign fibrohistiocytic tumours is generally excellent, with complete cure in most cases. However, some cases may recur or progress to malignancy, so close follow-up and surveillance is important.
