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.

Thoracic Ultrasound: Technique, Applications, and Interpretation.

Thoracic ultrasound is used at the bedside in emergency and critical care settings. Advantages of ultrasound include rapid real-time, low-cost, diagnostic information that can direct patient care without the use of ionizing radiation. We describe methods on how to perform lung ultrasound, with the intent to educate the radiologist who might otherwise be relatively unfamiliar with thoracic sonography.

Metastatic Malignant Ovarian Steroid Cell Tumor: A Case Report and Review of the Literature.

We report a case of malignant ovarian steroid cell tumor not otherwise specified (NOS) in a 47-year-old female who presented with hirsutism, virilization, and amenorrhea. At the time of laparotomy, the tumor had already spread to the pelvic cul-de-sac. She underwent a total hysterectomy, bilateral salpingo-oophorectomy, and tumor resection with no residual disease.

"STOP, LOOK, and LISTEN." Hepatic Portal Venous Gas: Time for Clinical Assessment!

Pneumatosis intestinalis and portal venous gas are findings usually associated with intra-abdominal surgical catastrophes that frequently require emergent surgical intervention. Herein we present a case of a patient who presented in septic shock, with extensive portal vein gas, diffuse intestinal wall thickening, and atherosclerotic vascular insufficiency in the absence of pneumatosis intestinalis. Given his advanced age, multiple comorbidities, magnitude of the initial findings, and his dramatic clinical response to aggressive fluid resuscitation, a cognitive decision was made to continue with nonoperative management.
