Extra-osseous Ewing sarcoma of the pancreas: case report with radiologic, pathologic, and molecular correlation, and brief review of the literature.

In 2002, due to extensive histomorphologic, immunohistochemical, and cytogenetic similarities, the World Health Organization unified undifferentiated small round blue cell neoplasms of soft tissue and bone (previously segregated as Ewing sarcoma or Primitive Neuroectodermal tumor) into one category: Ewing family of tumors (EFT). Osseous EFT are more common, and while extra-osseous EFT can occur anywhere in the body, those of the pancreas are rare and likely to be seen in the second decade of life in the head of the pancreas. We report the case of a 39-year-old Caucasian male with a large heterogeneously enhancing mass in the pancreatic body.

The Effect of Faster Reporting Speed for Imaging Studies on the Number of Misses and Interpretation Errors: A Pilot Study.

Purpose: The purpose of the study was to determine if increasing radiologist reading speed results in more misses and interpretation errors.

Methods: We selected a sample set of 53 abdomen-pelvis CT scans of variable complexity performed at a teaching hospital during the study period. We classified the CT scans into 4 categories based on their level of difficulty, with level 4 representing the most-complex cases.

Case Report: Primary Leiomyosarcoma of the breast with unusual metastasis to the femur.

With less than 40 cases reported, primary leiomyosarcoma is an extremely rare form of breast cancer (less than 0.0006% of cases) with unpredictable biological behavior that usually presents as a slow growing, mobile mass in middle age women. Most cases are low-grade and are cured by complete excision with wide margins.
