<p><strong>Background:</strong> Gastric carcinomas have various pathological features. Based on patterns of growth and invasiveness, however, they fall into two types: diffuse type and intestinal type. These two types of carcinoma appear to be different in their histogenetic origins.</p><p><strong>Objectives:</strong> To analyse various types of gastric cancer reported in last five years. To compare the features of intestinal and diffuse type gastric carcinoma including gross appearance, staging, grading of tumor.</p><p><strong>Materials and Methods:</strong> This was a retrospective study of 324 gastric cancer which were surgically resected and received over 5 years. The tumors were divided into groups according to their gross and microscopic patterns. Gross appearance was classified based on Borrmann classification. Microscopic features evaluated include tumor cell type, extent of invasion, degree of maturation, formation of glandular structures, nodal metastasis.</p><p><strong>Results:</strong> Totally 320 cases of gastric cancer were received of which 218(68%) were male, 102(32%) were female. Gastric cancers are rare below the age of 30 years. Comparing the type of gastric cancer intestinal type were 269(84%), diffuse type were 24(7.5%) and other type of gastric cancer including GIST, lymphoma, mucinous adenocarcinoma were 27(8.5%). Younger patients have higher stage of lymph node metastasis in diffuse type, but not for the intestinal type.</p><p><strong>Conclusion:</strong> Gastric cancer more common in male (M:F= 2:1) and most frequently seen in 5th decade. Intestinal type constitutes the most common type of gastric tumor. Gross appearance of diffuse type was predominantly infiltrative (79%).</p>
