Introduction: Large intestine is affected by various types of lesions, both non-neoplastic and neoplastic. Due to vague symptoms, the clinical diagnosis is usually delayed. A battery of laboratory tests including biopsy is essential to arrive at a specific diagnosis for appropriate management.
Materials and Methods: This five years study was done during the period of 2005 to 2010 in a tertiary care centre which included 124 biopsies and resected specimens of large intestine and 64 from Anal canal. All tissues were fixed in formalin, stained with H&E and special stains like Periodic Acid Schiff (PAS), Reticulin, Zeihl Neelsen (ZN) along with Immunohistochemistry (IHC) were done as and when required.
Results: Out of the 124 cases of large intestine 38 were non-neoplastic, 77 were neoplastic and 9 were inadequate biopsies. Sixty four cases from Anal canal included 55 non-neoplastic and 9 neoplastic lesions. The non-neoplastic conditions included congenital anomalies, infective and ischaemic lesions while neoplastic included benign and malignant lesions. Most of the cases presented with symptoms like abdominal pain, vomiting and constipation.
Conclusion: We observed that neoplastic lesions were more common in large intestine while non-neoplastic lesions were frequently seen in Anal canal. Present study emphasizes the need for early histopathological diagnosis for appropriate treatment.
