Özet
Neoplasms of the appendix are infrequent diseases that can be generally diagnosed with surgery or pathological examination. One of the most commonly fulfilled surgeries today is appendectomy. The neoplastic diagnoses that come out as a result of the examination of pathological specimens need to be well known. Even benign neoplastic diseases of the appendix may require extended follow-up periods and serious treatments if pseudomyxoma peritonei is involved. For example, serrated adenomas classified as benign may be dysplastic, and when they are diagnosed, the colonoscopic examination should be done to determine simultaneous colonic serrated polyps. Epithelial appendix neoplasm can be categorized as mucinous and non-mucinous. Their majority is mucinous neoplasm. Mucinous neoplasm causes pseudomyxoma peritonei without producing distant metastasis. Low-grade appendiceal mucinous neoplasms also hold the appendix wall, although in benign morphology, and may disseminate throughout the peritoneum. In benign pathologies, appendectomy may be sufficient provided that the disease is restricted to the appendix, no mucin or mucinous epithelium is detected outside the appendix serosa, and the resection border is clear. However, if these conditions are not provided or there is an appendix cancer, more painful surgical procedures are required. The peritoneal spread, lymphatic spread, and distant metastasis possibilities of appendix adenocarcinomas can be determined and treated according to the type of subdiagnosis (colonic-type, mucinous, or goblet cell). In this section, we tried to clarify the issue of appendix neoplasm.
