Appendix cancer, also known as appendiceal cancer, is a very rare malignant tumor that forms in the vermiform appendix.[7]
Gastrointestinal stromal tumors are rare tumors with malignant potential.[8] Primary lymphomas can occur in the appendix. Breast cancer, colon cancer, and tumors of the female genital tract may metastasize to the appendix.[9]
