Insights

This report details the first Indian case of cecal mucosa-associated lymphoid tissue (MALT) lymphoma, a rare condition. The MALT lymphoma presented as acute intestinal obstruction, highlighting its unusual presentation and location.

Area of Science:

  • Gastroenterology
  • Oncology
  • Pathology

Background:

  • Mucosa-associated lymphoid tissue (MALT) lymphomas are recognized lymphoid malignancies.
  • MALT lymphomas originating in the colon are exceptionally rare, with limited documented cases.
  • Colonic MALT lymphomas pose diagnostic challenges due to their rarity and varied presentations.

Purpose of the Study:

  • To report the first documented case of cecal MALT lymphoma in India.
  • To describe the clinical, radiological, and pathological features of this rare entity.
  • To emphasize the importance of considering MALT lymphoma in the differential diagnosis of colonic masses.

Main Methods:

  • Case presentation of a patient with acute intestinal obstruction.
  • Diagnostic workup including CECT scan and video colonoscopy with biopsies.
  • Surgical resection (right hemicolectomy) and histopathological examination with immunohistochemistry.

Main Results:

  • A 35-year-old male presented with symptoms of acute intestinal obstruction.
  • CECT revealed a mass in the right iliac fossa with diffuse thickening and lumen obliteration of the ascending colon and cecum.
  • Video colonoscopy showed circumferential ulcerated growth at the cecum; histopathology confirmed low-grade B-cell MALT lymphoma invading the muscular layer.

Conclusions:

  • Cecal MALT lymphoma is an extremely rare malignancy that can present as acute intestinal obstruction.
  • Multimodality imaging and endoscopic evaluation are crucial for diagnosis.
  • Histopathology and immunohistochemistry are essential for definitive diagnosis and classification of MALT lymphoma.

Intestinal Obstruction I: Introduction01:29

Intestinal Obstruction I: Introduction

Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...

Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...

Appendicitis01:19

Appendicitis

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...

Appendicitis-I: Introduction01:22

Appendicitis-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...

Assessment of the Rectum and Anus01:25

Assessment 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.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...
