Toxic haemorrhagic colitis: a rare presentation of eosinophilic colitis.

Eosinophilic colitis is a rare condition that usually presents with non specific abdominal symptoms. Very uncommonly it presents with an acute surgical emergency such as peritonitis or haemorrhage. We present a rare presentation of eosinophilic colitis with toxic hemorrhagic colitis and ischaemic bowel requiring laparotomy and bowel resection.

Critical analysis of mucin and signet ring cell as prognostic factors in an Asian population of 2,764 sporadic colorectal cancers.

INTRODUCTION: Conflicting data on the clinicopathological characteristics as well as prognosis and survival of signet ring cell (SRC) and mucinous adenocarcinomas (MA) of the colorectum persist. METHODS: Consecutive patients (2,764) with sporadic colorectal cancer from 1999 to 2005 were evaluated. The clinicopathological characteristics of these patients were reviewed. Univariate analysis was performed, and survival curves were constructed using the Kaplan-Meier method. Multivariate analysis assessed independent prognostic factors. RESULTS: The incidence of MA and SRC is 6% and 1.1%, respectively. MA and SRC tend to occur in patients aged
