Primary adenocarcinoma of the appendix.

A case of primary adenocarcinoma of the appendix in which the patient had the usual symptoms of acute appendicitis is presented. A review of the literature showed the potential for early extension and nodal metastasis in this lesion and led to the recommendation of right hemicolectomy as the treatment of choice. The operation should be done either primarily or secondarily after an appendectomy and should lead to a five-year survival of approximately 45%. Every effort should be made to make the diagnosis and provide definitive treatment at the primary operation by examining the appendix grossly and obtaining frozen section microscopic study of any suspicious tumor or ulceration.
