Non-Invasive Diagnosis of Pulmonary Kaposi Sarcoma: A Case Report

Abstract

Pulmonary Kaposi sarcoma (KS) is a low-grade malignant neoplasm associated with human herpesvirus-8 (HHV-8), seen predominantly in immunocompromised hosts. Classically, diagnosis relies on the combination of clinical history, exclusion of alternative infectious and neoplastic etiologies, and histopathologic confirmation of proliferating spindle cells staining positive for HHV-8. Tissue-based diagnosis requires bronchoscopy with biopsy and is associated with procedural complications, such as bleeding and pneumothorax.
