Differentiating between benign hepatocellular adenoma (HA) and carcinoma (HCC) is important for making clinical management decisions but can be challenging. We have reported liver tumor patients being discrepantly diagnosed as or based on different interpretations of identical histologic pattern - acinar/pseudoglandular pattern. In the study early hepatocarcinogenesis, it was proposed more than...

INTRODUCTION A collision tumor is the meeting and eventual intermingling of two malignant neoplasms arising from independent topographical sites. Collision metastasis of carcinomas in the lymph nodes is a rare event. A literature search revealed only three cases of such a collision metastasis of prostatic and urothelial carcinoma, and only one of those cases had used immunohistochemical stains ...

Background: Colorectal carcinoma is a malignant epithelial tumor originating in the large bowel. More than 90% of colorectal carcinomas (CRC) are adenocarcinomas. This being graded morphologically at H&E stain histopathology as well-differentiated, moderately differentiated, and poorly differentiated. Aims Objectives: The aim this study to assess any association with different histopatholog...

CONTEXT Pancreatic cancer is frequently complicated by malignancies in other organs. However, synchronous triple cancers including pancreatic cancer have been seldom reported in the English language literature. CASE REPORT We describe the rare case of a 77-year-old man with triple cancers of the pancreas, stomach, and cecum. Biopsies revealed that all three tumors were adenocarcinomas. The pa...

Clear cell adenocarcinoma of the colon has been described scarcely in the literature. It affects elderly men more commonly than women and usually appears in the left side of the colon. A Hispanic 41-year-old female came to the emergency room with abdominal pain, vomiting, and distension. Physical exam revealed generalized tenderness without peritoneal signs. Laboratory data was unremarkable. A ...

A 78-year-old male patient presented with double vision, painless palpable mass under the right superolateral orbital rim, downward displacement and restricted adduction of the right eye. His visual acuity was 20/50 OD and 20/20 OS. Hertel exophthalmometry was 21 mm OD and 17 mm OS. Computed tomographic scans showed an infiltrative orbital mass with ill-defined, irregular margins, involving the...

INTRODUCTION Current grading system in application by WHO/ISUP divides urothelial malignancies in low and high grade by morphologic criteria while strict segregation may become cumbersome in limited tissue specimens. As grading these carcinomas are of utmost prognostic significance after depth of invasion, therefore we evaluated the role of immunohistochemical expression of p53 and cytokeratin ...
