1. Tumors presenting as acute appendicitis.    1) Acute appendicitis mimicking cancer    2) Tumors presenting as acute appendicitis      - Infected mucinous neoplasm of appendix, Neuroendocrine tumor, Non-mucinous appendiceal cancer 2. Tumors masquerading as periappendiceal abscess    1) Chronic inflammatory condition mimicking cancer.        - Periappendiceal abscess mimicking cancer, Chronic xanthogranulomatous appendicitis, Endometriosis,      Actinomycosis    2) Tumors masquerading as periappendiceal abscess       - Colon cancer (cecum, appendix), Ovarian cancer, Gastrointestinal stromal tumors, Lymphoma 3.
