Summary
Classic Kaposi Sarcoma (KS) rarely presents in the jejunum, a finding typically seen in the gastrointestinal tract. This case highlights the importance of upper endoscopy for diagnosing rare gastrointestinal KS presentations.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Classic Kaposi Sarcoma (KS) commonly affects mucosal surfaces, including the oral cavity and gastrointestinal (GI) tract, in approximately 10% of patients.
- Primary KS in the GI tract is exceptionally rare, with limited documented cases, predominantly in the colon.
Observation:
- A 35-year-old male presented with symptoms of bowel obstruction.
- Diagnostic investigations revealed primary classic Kaposi Sarcoma located in the jejunum.
Findings:
- This case represents the first documented instance of primary classic KS in the jejunum within the country.
- The rarity of reported GI KS cases may stem from underdiagnosis or misdiagnosis.
Implications:
- The findings suggest that upper gastrointestinal endoscopy should be considered in select patients with classic KS to rule out GI involvement.
- Increased awareness and diagnostic vigilance are crucial for identifying rare presentations of Kaposi Sarcoma in the gastrointestinal tract.
