[Tumors of the appendix]

Neoplasms involving the vermiform outgrowth are among the rarely met with conditions, accounting for 0.1 to 0.5 per cent of all gastrointestinal tract tumors. This is a report on personal observation of three patients presenting tumors of the appendix, diagnosed over the period 1987 to 1995. As shown by the results, tumors of the appendix run a clinical course characterized by two distinct forms: clinical picture of acute appendicitis--two cases, and clinical picture of tumor of the colon--one case. It is underscored that intraoperative diagnosis is extremely difficult. The diagnosis is usually made by pathoanatomist, while the therapeutic approach and operative tactics are determined on the ground of histomorphological study results and local operative status. The scope of operative intervention includes appendectomy and right hemicolectomy.
