Additionally, the fluid wave sign on the liver surface further supported the diagnosis of PMP, characterized by the accumulation and redistribution of mucin within the peritoneal cavity.[13] The mucin and tumor cells, moving with the flow of ascitic fluid, redistribute under the influence of lymphatic spaces and lymphatic cells, leading to the preferential accumulation of tumor cells in areas such as the pelvis, mesocolon, greater omentum and hepatic capsule. This evidence concerns the gene MUC5AC and neoplasm.
