Abstract

Background: Colon and rectum are affected by various non-neoplastic and neoplastic lesions. Biopsy is essential in many lesions because of delay in diagnosis due to vague symptoms.

Objective: The present study was done to evaluate etiological pattern of colorectal lesions and prevalence of malignant lesions on histopathological examination of biopsies and specimens.

Material and Methods: The present study was conducted in the Department of Pathology, M.G.M. Medical College Indore, from January 2016 to December 2017. Total 104 cases were studied. The diagnosis in all the cases were made on Hematoxylin and Eosin stained slides of processed tissue.

Results: Out of 104 cases, 77 (74%) were males and 27 (26%) were females with age range from infant to 80 years. Among 104 cases 18 (17.3 %) shows acute non specific colitis, 10 (9.62 %) shows chronic non specific colitis, 08 (7.69 %) shows tuberculosis, 12 (11.56 %) shows ischemic colitis, 05 (4.8 %) shows Juvenile rectal polyp, 07 (6.73 %) shows adenomatous rectal polyp, 12 (11.56 %) Hirschprung’s disease, 01 (0.96 %) shows crohn’s disease, 02 (1.92 %) Ulcerative colitis, 04 (3.84 %) shows Haemorrhoids, 17 (16.34 %) shows adenocarcinoma, 05 (4.80 %) shows mucinous adenocarcinoma, 02 (1.92 %) shows squamous cell carcinoma and 01 (0.96 %) shows malignant melanoma.

Conclusion: Majority of cases were non-neoplastic lesions, among which common finding were acute and chronic non specific colitis. Among neoplastic lesions, most common was adenocarcinoma colon. Biopsy is important investigation for diagnosis of malignant colorectal lesions.
