INTRODUCTION. The primary adenocarcinoma of vermiformis appendix is a uncommon disease with an exceptional preoperative diagnosis and with many criteria on surgical treatment. The objective of present study was to determine the incidence of this disease and to identify the diagnostic elements and the options of treatment adapted according the postoperative follow-up results. METHODS. A descriptive and prospective study was conducted in 10 patients with a histopathological diagnosis of primary adenocarcinoma of vermiformis appendix, operated on the "Saturnino Lora"" Teaching Provincial Hospital of Santiago de Cuba province for 19 years (1990-2008). Patients were seen in the postoperative follow-up consultation of colorectal carcinoma and with a prescription of adjuvant mono-chemotherapy with 5-fluoruracil. RESULTS. The series represented the 0,12% of appendectomy patients and the 3% of those seen during this period. There was predominance of male sex aged over the fifth decade of life and clinical manifestations similar to acute appendicitis. The 70% of them undergoes right hemicholectomy from invasive primary adenocarcinoma and the remainder undergoes appendicectomy. The 5-years course was satisfactory in 8 patients; 2 deceased from tumor recurrence two years after initial surgery. CONCLUSIONS. All the appendixes removed must to be examined by pathologic histology to detect this uncommon entity which the surgeon neither always may to diagnose before surgery nor during it, since could to get confused with the acute appendicitis. The right hemicholectomy is justified in the invasive type and the appendicectomy in the non-invasive adenocarcinoma whenever the patients receive a adjuvant treatment and to attend to consultation of postoperative follow-up.
