# Kaposi Sarcoma: Almost Forgotten but Occasionally There

## TL;DR

Kaposi sarcoma is a rare cancer often linked to HIV, immunosuppressants, or African populations, and PET-CT is now the main imaging tool for diagnosis and monitoring.

## Contribution

Highlights the role of PET-CT as the primary radiological method for diagnosing and following up on Kaposi sarcoma.

## Key findings

- Kaposi sarcoma is rare and mainly affects HIV-positive individuals, those on immunosuppressants, or African patients.
- PET-CT is currently the primary imaging technique used for diagnosis and monitoring of the disease.

## Abstract

Teaching point: Kaposi sarcoma is a rare disease most commonly occurring in patients with human immunodeficiency virus (HIV), in patients receiving immunosuppressants or in African patients. Radiological imaging has a role in facilitating the diagnosis and follow‑up, currently primarily with positron emission tomography–computed tomography (PET‑CT) (1).
