Gastrointestinal Kaposi's Sarcoma Presenting as Ileocolic Intussusception

Area of Science:

• Oncology
• Gastroenterology
• Infectious Diseases

Background:

• Kaposi's sarcoma (KS) is a common neoplasm in patients with acquired immune deficiency syndrome (AIDS).
• Gastrointestinal (GI) involvement with KS typically occurs with cutaneous or lymph node disease, with isolated GI tract involvement seen in only 3.5% of cases.
• While often asymptomatic, GI KS can manifest as hemorrhages in the digestive tract.

Observation:

• This case report details a unique presentation of GI KS.
• The patient lacked skin manifestations, and the initial symptom was acute intestinal intussusception and obstruction.
• Nodular mass lesions were identified in the stomach and GI tract, indicative of GI KS.

Findings:

• The case demonstrates a rare instance of KS presenting solely as GI involvement.
• Intestinal intussusception and obstruction were the primary clinical manifestations.
• Diagnosis was confirmed through nodular mass lesions in the GI tract.

Implications:

• Physicians should consider GI KS in the differential diagnosis for HIV-positive patients with recurrent abdominal pain.
• The absence of typical skin lesions can pose a diagnostic challenge.
• Early recognition of isolated GI KS is crucial for appropriate management and prognosis in AIDS patients.
