Insights

Myeloid sarcoma, a rare gastrointestinal manifestation of acute myeloid leukemia (AML), can present as the sole initial symptom. This case underscores the diagnostic challenges and critical need for prompt identification of this aggressive disease.

Area of Science:

  • Oncology
  • Hematology

Background:

  • Myeloid sarcoma can precede acute myeloid leukemia (AML) and may be its only initial presentation.
  • Gastrointestinal involvement by AML is uncommon, typically affecting the small intestine and presenting with vague abdominal pain or obstruction.

Purpose of the Study:

  • To report a challenging case of primary gastrointestinal myeloid sarcoma.
  • To emphasize the diagnostic difficulties and the importance of prompt management.

Main Methods:

  • Case report of a 25-year-old male with prolonged abdominal pain and vomiting.
  • Diagnostic procedures included esophagogastroduodenoscopy (OGD) with biopsy, ileal resection, histology, immunohistochemistry, and bone marrow examination.

Main Results:

  • Initial OGD revealed gastric infiltration; subsequent ileal resection was performed for acute intestinal obstruction.
  • Histology initially suggested non-Hodgkin's lymphoma, but immunohistochemistry confirmed myeloid sarcoma.
  • Bone marrow investigations confirmed concurrent AML, and the patient ultimately succumbed to the disease.

Conclusions:

  • Primary gastrointestinal manifestation of AML, such as myeloid sarcoma, poses significant diagnostic challenges.
  • Early and accurate diagnosis through immunohistochemistry and bone marrow assessment is crucial for timely intervention and management.

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: 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...
