The 2 major histologic tumor subtypes are serous and mucinous, with serous being more common. Serous tumors are presumed to originate from the germinal epithelium. Mucinous tumors do not have a clearly defined origin. Substantial information indicates that many tumors may actually originate from the appendix; thus, this organ should be removed at the time of surgery.
