Summary
Mesoappendiceal lesions are rare but can be clinically significant. Careful pathological examination of appendectomy specimens is crucial for identifying these often-overlooked findings, including infections and tumors.
Area of Science:
- Gastroenterology
- Pathology
- Surgical Pathology
Background:
- Lesions of the mesoappendix are uncommon and frequently overlooked during routine pathological examination of appendectomy specimens.
- While often benign and incidental, mesoappendiceal lesions can encompass a range of infectious, tumor-like, and neoplastic conditions with clinical implications.
Purpose of the Study:
- To highlight the importance of thorough gross examination of the mesoappendix in appendectomy specimens.
- To determine the spectrum and frequency of mesoappendiceal and periappendiceal lesions.
Main Methods:
- Retrospective review of 4371 appendectomy specimens over a four-year period.
- Detailed gross examination and sectioning of the mesoappendix were emphasized.
Main Results:
- Eight cases (0.18%) of mesoappendiceal or periappendiceal lesions were identified.
- Findings included benign entities (e.g., reactive lymph nodes, ectopic decidua), an inflammatory fibroid tumor, and clinically significant infections (tuberculosis, schistosomiasis).
- Lesions were more prevalent in young adult males (male to female ratio 7:1).
Conclusions:
- Thorough pathological examination of the mesoappendix is essential for detecting rare but potentially significant lesions.
- Increased awareness and meticulous grossing techniques can improve the identification of these findings, aiding patient management.

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:22Appendicitis-I: Introduction
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...

01:26Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

01:21Peritoneum
The peritoneum is a vital membrane that lines the abdominal cavity and covers most of the organs within it. It plays a crucial role in protecting the organs, providing a smooth surface for their movement, and facilitating various physiological processes. Understanding the anatomy and function of the peritoneum is essential for comprehending the complexities of the abdominal region.

01:25Assessment of the Rectum and Anus
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.

01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
