Summary
Anal canal adenocarcinoma is rarely found in internal hemorrhoid specimens. Routine pathological analysis of hemorrhoidectomy specimens is recommended for early detection of this rare cancer.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Oncology
Background:
- Carcinoma within internal hemorrhoid specimens is exceptionally rare.
- Primary anal canal adenocarcinoma is even more infrequently found within internal hemorrhoids.
- This report details a rare case of anal canal adenocarcinoma discovered in an internal hemorrhoidectomy specimen.
Observation:
- A 79-year-old male presented with rectal bleeding and was diagnosed with internal hemorrhoids.
- Screening colonoscopy revealed large thrombosed internal hemorrhoids.
- Pathologic analysis of the hemorrhoidectomy specimen identified a 1.5 cm adenocarcinoma of anal origin.
Findings:
- The adenocarcinoma showed moderate-to-poor differentiation with superficial submucosal invasion.
- The patient underwent biopsy and re-excision for a non-healing wound with no recurrence.
- At ten-month follow-up, the patient was cancer-free.
Implications:
- An interdisciplinary approach is crucial for managing primary anal canal adenocarcinoma.
- Routine pathological examination of hemorrhoidectomy specimens can aid in timely diagnosis and treatment.
- Early detection of anal canal carcinoma is vital due to its potential severity.

01:25Assessment of the Rectum and Anus
709
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

01:22Appendicitis-I: Introduction
1.2K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
