Pigmented Paraganglioid Carcinoid Tumors of the Lung: Spatial Transcriptomics Reveals Shared and Distinct Features with Typical Carcinoid Tumors and Extra-Adrenal Paragangliomas

2025-12-02

Abstract excerpt

Pigmented paraganglioid carcinoid tumors (PPCT) of the lung are a rare, underrecognized, and poorly characterized morphologic variant of pulmonary neuroendocrine tumors (NETs). While these tumors are usually diagnosed as typical carcinoid (TC) tumors, PPCT may represent a diagnostic challenge due to the histologic resemblance with extra-adrenal paraganglioma (PG). In this study, we aimed to comprehensively charact...
