Xanthoma cells are a type of amorphous bacteria that are part of the normal flora in the human body. They have an unusual shape, similar to foam spheres, and contain many small cells that are separated from each other by partitions. In most cases, they are harmless and do not cause disease when ingested without any other conditions. This allows Xanthoma cells to be an important component of many drugs for the treatment of fungal infections and other diseases. Although they are a byproduct of normal bacteria in the human gut, these cells can cause allergic reactions and promote the growth of malignant tumors if they enter the bloodstream and spread throughout the body. That is why in some cases they act as biomarkers for stomach cancer, etc.
