Duodenal Metastasis of Pulmonary Pleomorphic Carcinoma: A Case Report

Pulmonary pleomorphic carcinoma (PPC) is a rare subtype of lung sarcomatoid carcinoma that has a poor prognosis, and no standard therapy has been established. Here, we report the case of a 74-year-old man with PCC who showed rare duodenal metastasis. He was referred to our hospital with a mass shado...
