"The tumour may derive from smooth muscle cells of the bile ducts or blood vessels. No underlying aetiologic factors are known. Not associated with cirrhosis, but may be related to EBV. C-kit negative (differentiates it from GIST)."

"Surgical resection is the standard treatment but with the rarity of the tumour, its effectiveness is uncertain. It had previously been reported that the majority of patients have recurrent tumour and some develop widespread metastatic disease, however, some studies suggest that this prognosis was based on some earlier misclassification of GIST tumours as hepatic leiomyosarcomas 5,7. The clinical course of a pedunculated leiomyosarcoma may be benign 6."
