Core Tip

Core Tip: Large cell neuroendocrine carcinoma (LCNEC) of the bladder is a rare non-urothelial tumor of the bladder. As LCNEC is a rare disease and its clinical symptoms and radiographic features mimic those of urothelial tumors, it may be misdiagnosed as urothelial carcinoma. In this article, we report a patient with LCNEC of the bladder, who was not accurately diagnosed due to the absence of immunohistochemical examination before surgery. We summarize the methods for diagnosing and treating LCNEC of the bladder and highlight the importance of early diagnosis and multimodal treatment.
