Abstract

A rhabdoid cholangiocarcinoma is a very rare variant of sarcomatous cholangiocarcinomas. Here, we report a vimentin positive cholangiocarcinoma showing rhabdoid features in the entire tumor, with a very aggressive behavior. A 41-year-old woman was admitted to our hospital due to a huge hepatic mass. The resected liver revealed a 17x15cm sized solid mass with extensive necrosis and an infiltrative border. On microscopic examination, the entire tumor was composed of loosely cohesive round to polygonal cells, with rhabdoid features having abundant eosinophilic glassy cytoplasm and eccentrically located vesicular nuclei. Some tumor cells contained intracytoplasmic mucin vacuoles, but definite areas of glandular differentiation or spindle cell were not found. Immunohistochemical staining showed a diffuse strong positive reaction to pan-cytokeratin and vimentin, and focal positivity for the carcinoembryonic antigen. Other immunohistochemical stainings for cytokeratin 7, cytokeratin 20, S-100 protein, HMB-45, desmin, alpha-smooth muscle actin, c-kit, CD34, alpha-fetoprotein, anti-hepatocyte antigen, chromogranin and synaptophysin were all negative. After two months, the patient developed a local recurrence along the resection margin, and multiple hematogenous metastases to the lung and liver were seen on the follow-up CT scan.
