Abstract

Background:

Myelodysplastic syndromes (MDSs) are clonal hematopoietic disorders often associated with cytogenetic abnormalities, among which trisomy 8 is one of the most common abnormalities. Trisomy 8 is linked to autoimmune manifestations, including Behçet-like disease, especially with gastrointestinal involvement.

Case Presentation:

We report a rare and severe case of a 59-year-old male with MDS characterized by a complex abnormal karyotype, including trisomy 8, accompanied by multiple ileal perforations and intestinal ulcers resembling Behçet's disease. Despite surgical intervention and broad-spectrum antimicrobials, recurrent symptoms persisted. A combination of corticosteroids and thalidomide ultimately led to clinical and hematologic improvement.

Methods:

Clinical, radiologic, histopathologic, and cytogenetic data were collected. Literature review was conducted to contextualize diagnostic criteria and treatment strategies.

Results:

The patient showed hematologic and symptomatic improvement following immunosuppressive therapy. Chromosome karyotype analysis revealed chromosomal numerical abnormalities, including trisomy of chromosomes 8, 9, and 15 and the presence of an extra Y chromosome. Gastrointestinal involvement with recurrent perforations was attributed to Behçet-like intestinal disease.

Conclusion:

This case underscores the aggressive clinical course and diagnostic challenges of Behçet-like disease associated with MDS and trisomy 8, highlighting the importance of early recognition and immune-targeted therapy.

Chronic Bowel Disorders: Introduction

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
Clinical Manifestations:

Inflammatory Bowel Disease I: Ulcerative Colitis

Inflammatory Bowel Disease I: Ulcerative Colitis

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Esophageal Perforation-I: Introduction

Esophageal Perforation-I: Introduction

Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

Inflammatory Bowel Disease V: Surgical Management

Inflammatory Bowel Disease V: Surgical Management

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:
