title: Primary adenocarcinoma of the appendix.
abstract: Two cases of carcinoma of the appendix presenting as appendicular masses are discussed. Carcinoma of the appendix is rare and hence a pre-operative diagnosis is seldom made. Awareness of the condition would naturally arouse suspicion of its presence, especially in elderly patients who present with cute appendicitis or an appendix mass. It is known to have occurred in an appendix stump several years after the initial appendicectomy, and also in a 17-year-old patient. The need for histological examination of all appendicetomy specimens is stressed. The operation of choice is right hemicolectomy, either as a primary or as a secondary procedure. This is associated with better survival rates than when the condition is treated by appendicectomy alone.
