TMPRSS2-ERG is the most common gene fusion in conventional prostatic adenocarcinoma (PCa), identified in about 40% to 70% of cases. Mucinous PCa and PCa with mucinous features are rare subtypes of prostate cancer, and ERG expression in these subtypes has not been well characterized in a large series. A search was made through the surgical pathology and(More)
OBJECTIVE A combined thyroid transcription factor 1 (TTF-1) and Napsin A double stain has been shown to be useful in the diagnosis of adenocarcinoma (ADC). This study compares differences in double staining patterns among vendor antibodies (Leica, Dako, and Biocare). STUDY DESIGN The cohorts included 35 FNA cell blocks of lung ADC and 24 cell blocks of(More)
Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the most sensitive and specific test for establishing a tissue diagnosis for many gastrointestinal malignancies; however, cytologic morphology alone may not be definitive for subsets of tumors. Our aim was to quantify the impact of the broad application of flow cytometry (FC) and(More)
