"A Tale of 2 Demons"-Concomitant Presence of Hepatocellular Carcinoma and Primary Neuroendocrine Tumor of Liver: A Case Report and Review of Literatures.

Neuroendocrine tumors usually originate from the neuroendocrine cells of gastrointestinal tract and their presence in the liver is mostly in the form of metastases. A primary neuroendocrine tumor in the liver concomitantly with hepatocellular carcinoma is an infrequent phenomenon. We present a 66-year-old woman with a remote history of breast cancer coming with postprandial fullness, later found to have multiple liver masses.

Salivary duct carcinoma with striking neutrophil-tumor cell cannibalism.

Cannibalism of neutrophils by tumor cells has previously been reported in certain carcinomas, lymphoma and melanoma. Tumor cannibalism is believed to serve as a tumor-immune escape mechanism, associated with high-grade aggressive cancers with a significantly increased metastatic potential. This interesting phenomenon has not been previously documented in association with salivary gland tumors.

Mesothelioma in an HIV/AIDS patient without history of asbestos exposure: possible role for immunosuppression in mesothelioma: a case report.

We describe a 41-year-old African-American male who initially presented in respiratory distress. He had a positive history of asthma, cigarette smoking, and only recent possible asbestos exposure six months prior to onset of symptoms. Mesothelioma was suspected after chest radiography and PET-CT, and confirmed by immunohistochemical tissue analysis.
