Poorly differentiated cecal adenocarcinoma showing prominent rhabdoid feature combined with appendiceal mucinous cystadenoma: A case report and review of the literature.

Extrarenal rhabdoid tumors (ERRTs) are extremely rare neoplasms; of these, colorectal ERRTs are the most rare, and only nine cases have been previously described in the English language literature. The current study reports the pathological features of a case of poorly differentiated cecal adenocarcinoma with prominent rhabdoid feature, which was combined with mucinous cystadenoma of the appendix in a 73-year-old male, and additionally reviews the previously reported cases. Microscopically, the majority of tumor cells were non-cohesive or loosely cohesive, with a polygonal morphology and prominent rhabdoid feature, showing eccentric vesicular nuclei, prominent nucleoli and abundant eosinophilic cytoplasm.

Double primary hepatic cancer (sarcomatoid carcinoma and hepatocellular carcinoma): A case report.

Primary liver sarcomatoid carcinoma (SC) is a rare and aggressive tumor exhibiting rapid growth and a high recurrence rate following resection. To date, there have been no reports of primary liver SC occurring simultaneously with hepatocellular carcinoma (HCC). This is the case report of a 54-year-old man with liver cirrhosis due to hepatitis B virus (HBV) infection and alcoholic hepatitis.
