Kaposi Sarcoma in Two Lung Transplant Recipients: A Single-Center Experience.

Kaposi's Sarcoma (KS) is a malignant vascular tumor commonly seen in immunocompromised individuals, particularly patients with acquired immunodeficiency syndrome. Lung transplant recipients are at high risk of developing KS due to a strong immunosuppressive regimen that can lead to donor-derived infection or reactivation of recipient human herpesvirus 8, the causative organism for KS. In this overview, we describe 2 lung transplant recipients who developed pulmonary KS with poor outcomes, reviewing the diagnosis, bronchoscopy findings, and treatment and surveillance strategies for pulmonary KS.
