The bile duct cancer pathology changes

1.The occurrence part of the liver outside bile duct cancer.On the anatomy, part take place according to the cancer, the bile duct cancer outside the liver can is divided into:①The or so liver takes care of a cancer;②Liver manager cancer;③The gall bladder takes care of a cancer;④The liver manager, gall bladder tube and Dan manager remit to match a cancer;⑤Dan manager cancer.
2.The big body appearance of the liver outside bile duct cancer:The bile duct cancer outside the liver can is divided into 3 on the big body appearance:①Take care of wall gradually type:It is thus clear that at any part of bile duct, most for much see.Because the tube wall implicating increases thick, can to tube the chamber diminish or narrow, then can take place to jam a phenomenon.②Knot a stanza type:More take care of wall gradually the type is seldom seen, it is thus clear that in compare the bile duct cancer in later period, the diameter of cancer knot stanza can 1.5~5.0 cms.③Nipple-like in shape type inside the chamber:At least see, it is thus clear that at any part of bile duct, but remit to match a department more seldom seen.This type of can jam a bile duct chamber completely.In addition to mainly growing inside the chamber to the tube, cancer organization may also further to take care of to gradually grow inside the wall.
3.The histology type of the liver outside bile duct cancer:According to the type of cancer cell, divide a degree and cancer organization growth way.The bile duct cancer outside the liver can is divided into following 6:⑦Nipple-like in shape gland cancer:In addition to separately is take care of wall gradually type, almost and all is a nipple-like in shape type inside the chamber.②The high mark turns a gland cancer:In the bile duct cancer can have above 2/3 at most, it is thus clear that at any part.The cancer organization all is taking care of to gradually grow inside the wall and surround the whole tube wall.Gradually of the cancer organization present size etc. not, shape irregular gland body structure, have of can extend to present a bag chamber.③The low mark turns a gland cancer:Namely divide a bad gland cancer, the cancer organizes part to present gland body structure, the part is irregular of solid sex slice piece, as well at take care of inside the wall fill the air gradually growth.④Don't divide a cancer:Less see.Some cellules didn't divide a cancer, with gall bladder of don't divide a cancer homology, the cancer cell is in the bile duct wall fill the air gradually, quality less.The cancer organization hits a little bit greatly, often can invade and the bile duct surrounding organ of fat organization or close by.⑤Print to quit a cell cancer:Less see.It prints with gall bladder or stomach and intestines way to quit a cell cancer similar, from divide degree don't wait of imply the cancer cell that glue the liquid composing.Cancer cell the none settle structure, fill the air gradually.⑥Scale-like in shape cell cancer:Rare.It organizes the homology that appearance and other organs sees.
4.The bile duct cancer outside the liver spreads and transfers:In early days, occurrence assignor less, mainly is follow the bile duct wall gradually and directly spread upward and downward.As above segment liver tube the cancer can directly invade and liver, compare a medium and next cancer to much see.The lymphoid liver door department knot is most familiar to transfer, can also go to the lymphoid knot of the belly cavity other parts.The blood road transfers, unless is a later period cancer, generally and less.The bile duct cancer of each part, the liver transfers to at most see, particularly high bile duct cancer, the cancer organizes easy vein in the invasion door, the formation cancer blood bolts, can cause liver's transfering.Can also transfer to the close by organ pancreas, gall bladder.
