RESUMEN
Background: This study was conducted to determine relative frequency of various histopathological types of gastrointestinal (GI) tumours and to evaluate them in relation to age & sex of patients and location of tumours. Methodology: Histopathological study of 91cases of gastrointestinal tumours was carried out at AMC MET Medical College from January 2011 to June 2015. Results: Of total 91 cases, peak age distribution was in the sixth decade & male to female ratio was 2.03:1. GI tumours were more common in the colorectal region (38.46%), followed by esophagus (28.57%), stomach (19.78%), small intestine (9.89%), appendix (2.20%) & anal canal (1.10%). Benign & malignant tumours comprised 10.99% & 89.01% respectively. Among malignant tumours, adenocarcinoma was the commonest type (45.68%); followed by squamous cell carcinoma (32.10%), exclusively seen in esophagus. Conclusion: Gastrointestinal tumours show a wide variation in the morphology. So, histopathological examination is mandatory for the diagnosis.
