Imaging of Kaposi sarcoma

Area of Science:

• Oncology
• Dermatology
• Radiology

Background:

• Kaposi sarcoma (KS) is a multifocal vascular neoplasm.
• KS can manifest in various forms, affecting the skin and internal organs.

Purpose of the Study:

• To review the diverse clinical and imaging manifestations of Kaposi sarcoma (KS).
• To discuss differential diagnoses for KS imaging findings.
• To highlight molecular markers aiding KS diagnosis and therapy.

Main Methods:

• Literature review of KS imaging findings.
• Analysis of differential diagnoses for KS.
• Summary of relevant molecular markers for KS.

Main Results:

• KS presents with varied appearances on imaging studies.
• Several conditions mimic KS on imaging.
• Specific molecular markers are associated with KS subtypes and prognosis.

Conclusions:

• Accurate diagnosis of KS requires integrating clinical, imaging, and molecular data.
• Understanding KS imaging patterns and differentials is crucial for patient management.
• Molecular markers offer potential for targeted therapy in Kaposi sarcoma.
