HISTOPATHOLOGICAL STUDY OF LESIONS OF ANAL CANAL

Abstract

Background. Diverse diseases including congenital anomalies like Hirschsprung disease, anorectal agenesis, infections like tuberculosis, parasitic infestations, inammatory disorders like Crohn's disease ulcerative colitis, and neoplasms like adenomas, adenocarcinomas, squamous cell carcinoma etc, involve the anal canal. Despite its short length, the anal canal produces a variety of tumor types reecting its complex anatomic and histologic features (WHO). Majority of these disorders present with common symptoms like constipation, per rectal bleeding, altered bowel habits and difculty in defecation. The study was undertaken with the aim of a Aim: nalysing the histopathological lesions of anal canal with clinicopathological corelation. Total 116 lesions affecting anal canal over Materials and methods: a period of January 2013 to June 2017(4.5 years) were included in this study. Demographics of patients, presenting symptoms and pathologic features were recorded. Out of 116 Results: lesions, 106 were nonneoplastic, greatly outnumbering the eight neoplastic lesions. Anal stula was the most common lesion accounting for 49 cases. Most common age group affected was 31-40 years. Conclusion: Histopathological examination of every anal lesion is important since clinical presentation of neoplastic and nonneoplastic disorder is same. Rare entities like anal gland carcinoma can be diagnosed only on histopathology
