Long-term survival after curative left hepatectomy for mucin-producing cholangiocarcinoma : Report of a case

Cholangiocarcinomas are rarely mucinproducing. We report a case of mucin-producing cholangiocarcinoma successfully treated by curative left hepatectomy, resulting in long-term survival, with no evidence of tumor recurrence 111 months after resection. Immunohistochemical studies revealed a pattern of MUC-1 negativity and MUC-2 positivity, suggesting low malignant potential.
