The Use of a Novel Immunohistochemical Triple Cocktail in the Subclassification of Resected Non-Small Cell Lung Carcinomas: A Comparative Study With Morphology and Traditional Immunohistochemistry.

Therapy for non-small cell lung carcinoma (NSCLC) is currently determined by histologic subtype and the presence or absence of actionable mutations. Accurate subclassification is therefore essential for appropriate selection of cases for molecular studies and guiding treatment. The gold standard for subclassification of NSCLC is identification of differentiating morphologic features in correlation with diagnostic immunohistochemistry (IHC) in cases of poorly differentiated carcinoma.

Hepatic adenomatosis: a rare but important liver disease with severe clinical implications.

A 56-year-old white female presented to the emergency room (ER) with acute onset of right upper quadrant abdominal pain, nausea, and vomiting, and she was found to have a sudden drop in hemoglobin. Abdominal computed tomography (CT) with and without intravenous contrast revealed multiple bilobar focal hepatic hypervascular lesions, one of them demonstrating spontaneous rupture with active intraperitoneal bleeding. A moderate hemoperitoneum was present.
