Pralsetinib-Induced Interstitial Pneumonitis in a Patient with Metastatic Pulmonary Spindle Cell Carcinoma Harboring RET fusion: A Case Report

2026-03-05

Abstract excerpt

<title>Abstract</title> <p> <bold>Background:</bold> Pulmonary spindle cell carcinoma (PSCC), an exceptionally rare subtype of pulmonary sarcomatoid carcinoma (PSC), remains poorly characterized in terms of molecular alterations, rendering targeted therapy a promising option. RET gene fusions act as oncogenic drivers across multiple tumor types, and the emergence of selective RET tyrosine kinase inhibitors (TKI...
