Temporary spontaneous regression of intrahepatic cholangiocarcinoma

A 34-yr-old man with a liver mass was referred to the hospital, The mass showed temporary spontaneous regression during the follow-up, however, subsequent regrowth of the tumor prompted surgical resection, The specimen revealed intrahepatic cholangiocarcinoma with two distinct components which had been clearly demonstrated on serial CT, Spontaneous resolution of a lesion does not necessarily suggest the lesion's benign, self-limiting entity. Intrahepatic cholangiocarcinoma should be included in the tumors that could spontaneously regress. Copyright (C) 1996 Elsevier Science Ltd.
