title: Primary Pulmonary Lymphoma and Synchronous Cecal Adenocarcinoma: A Rare Occurrence.
abstract: In the era of extensive imaging and increasing indications for performing PET-CT scans, the recognition of synchronous tumors may be greater than before. However, the majority of these tumors are seen to occur in the same organ system, likely because of sharing similar pathogenic mechanisms. Synchronous lung cancers of similar or differing histologies have been reported. Primary pulmonary lymphoma, which is a rare form of non-Hodgkin's lymphoma, has also been seen with a synchronous primary lung cancer. However, we report a case of a 56-year-old male diagnosed with primary pulmonary lymphoma and on PET-CT imaging, found to have a cecal lesion, the biopsy of which showed adenocarcinoma. We discuss the incidence of the co-existence of multiple tumors, the pathogenic mechanisms involved, and approaches to the management of these rare clinical scenarios.
