Synchronous multiple neuroendocrine primary lung cancer with endobronchial extension in a never smoker - An unusual manifestation
Synchronous Lung Cancer primaries (SLC) are uncommon, with diverse underlying histology, constituting only a small proportion. The scarcity also poses a challenge in formulating a standardized diagnostic approach. Consequently, the diagnostic and staging challenges for SLC are heightened, particularly when the tumors are located on opposite sides of the chest. We report an exceptionally rare phenomenon in synchronous multiple primary lung cancers with simultaneous occurrence of two neuroendocrine tumors with endobronchial extension, small cell carcinoma and typical carcinoid tumor. Immunohistochemistry proved valuable in confirming the diagnosis. Given the poor prognosis associated with such cases, an accurate diagnosis is crucial for determining appropriate treatment options.
