Background: Common tumor metastasis sites for intrahepatic cholangiocarcinoma (ICC) include regional lymph nodes as well as liver metastasis as an indication of tumor recurrence. The main route for the spread of tumor cells is generally via lymph vessels. This lymphatic pathway could be responsible for a rapid spread of the disease and the high lethality associated with ICC. Here we present a case report of the first described prostatic metastasis from primary ICC. Case Presentation: A 77-year-old patient with a history of ICC who received mesohepatectomy (MH) with positive resection margins (R1) after initial surgery for a centrally located liver tumor presented to a tertiary hospital due to intermittent episodes of gross hematuria and obstructive micturition.During transurethral resection of the prostate (TUR-P) a large suspicious mass involving the left prostate lobe of prostate occurred. The histopathology report revealed a carcinoma showing the same histopathological and immunophenotypical features as the primary hepatic tumor. The patient develops an early tumor recurrence with metastases to the prostate, local lymph nodes and the liver after the primary surgical resection. He is now going to receive systemic chemotherapy as well as stereotactic radiofrequency ablation (SRFA) of liver for the liver metastases. Conclusion: This case report represents to our knowledge the first case of prostate metastasis from primary ICC.
