They often have a characteristic appearance which the radiologist can diagnose. However, there's no evidence that an untreated liver hemangioma can lead to liver cancer. [1] Upon cellular interaction and cross-signaling with their cognate follicular (Fo B) B cells, TFH cells trigger the formation and maintenance of germinal centers through the expression of CD40 ligand (CD40L) and the secretion of IL-21[2] and IL-4.
