RESUMEN
BACKGROUND AND OBJECTIVES: Isolated vasculitis of the gastrointestinal (GI) tract is a rare entity. Endoscopic biopsies have low sensitivity to diagnose intestinal vasculitis, even though the endoscopic findings may be suggestive of this condition. Our aims were to describe a case of biopsy-proven colonic leukocytoclastic vasculitis and review the literature. METHODS: A patient with biopsy-proven colonic leukocytoclastic vasculitis is described. A Medline database search of cases with localized GI vasculitis between January 1985 and September 2005 was conducted. RESULTS: A 32-year-old man was admitted to the hospital because of abdominal pain and diarrhea. A colonic biopsy showed leukocytoclastic vasculitis. There are very few articles on leukocytoclastic GI vasculitis as a separate disease, and most of them emphasize the difficulty in classification. Unlike our case, in former cases of localized vasculitis a diagnosis was made after surgery. Although our patient had steroid-refractory biopsy-proven isolated intestinal vasculitis, treatment with intravenous cyclophosphamide resulted in rapid resolution of symptoms and surgery was not required. CONCLUSIONS: In patients with abdominal pain a diagnosis of intestinal vasculitis should be considered. Immunosuppressive therapy allowed our patient to avoid surgery and may be similarly beneficial in other similar cases.

The aim of this study was to analyze the characteristics of the presentation and prognosis of patients aged >/= 80 who were diagnosed with gastric adenocarcinoma. We have used a retrospective cohort study of 2334 patients diagnosed between 1975 and 1993 in northwestern Spain, 263 (11.3%)of whom were >/= 80 years of age. No differences were observed with respect to patients of a younger age at diagnosis regarding the site of the tumor, extension of the disease, or Laurén's histologic type. However, fewer resections with curative intent were performed in the older group (49.1% vs. 30.1%; p < 0.0001). Among those operated on with curative or palliative intent, at the end of the first month the survival probability was 0.9 and the 0.95% confidence interval (CI 95%) was 0.93-0.97 for patients < 80 years of age and 0.93 (CI 95% 0.89-0.98) for the older group ( p = 0.19). At the end of 5 years of follow-up these probabilities were 0.29 (CI 95% 0.27-0.31) and 0.18 (CI 95% 0.14-0.23), respectively ( p < 0.0001). If we consider only those patients undergoing curative resection, the survival probability for the two groups ( p = 0.4) was not statistically different. In conclusion, although the two groups showed similar characteristics at presentation, patients >/= 80 years of age underwent surgery with curative intent less frequently and their general prognosis was worse. Our data support the idea that curative surgery should not be ruled out exclusively for reasons of age.
