Abstract:
Micropapillary urothelial carcinoma (MPUC) represents a rare but aggressive variant of urothelial carcinoma characterized by early lymphovascular invasion, distant metastasis, and poor clinical outcomes. We present a diagnostically challenging case of ureteral MPUC initially misdiagnosed as intestinal neuroendocrine tumor. After the pathological diagnosis was confirmed, the patient received adjuvant chemotherapy with gemcitabine and carboplatin. Despite therapeutic intervention, the patient developed widespread metastases and succumbed to the disease within 11 months of follow-up.
