OBJECTIVE The purpose of this study was to determine the diagnostic accuracy of CT in detecting mandibular invasion by squamous cell carcinoma of the oral cavity. MATERIALS AND METHODS Forty-nine patients who had squamous cell carcinoma of the oral cavity that was clinically fixed to the mandible were treated with mandibulectomy. All patients underwent(More)
BACKGROUND The increasing utilization of lymphatic mapping techniques for breast carcinoma has made intraoperative evaluation of sentinel lymph nodes attractive. Axillary lymph node dissection can be performed during the initial surgery if the sentinel lymph node is positive, potentially avoiding a second operative procedure. At present the optimal(More)
BACKGROUND Several well-controlled studies have demonstrated significantly increased local recurrence rates in patients with low-stage breast carcinoma treated with breast conservation therapy in whom focally positive margins were not reexcised. Imprint cytology is a rapid technique for evaluating surgical margins intraoperatively, thus allowing reexcisions(More)
BACKGROUND The evaluation of sentinel lymph nodes (SLNs) from a woman with lobular cancer of the breast is frequently challenging. Intraoperative imprint cytology (IIC) is equivalent to frozen sectioning for rapid SLN evaluation and is advantageous because it is rapid, reliable, cost-effective, and conserves tissue. Metastatic lobular carcinoma is difficult(More)
Yolk sac tumors (YST) in extragonadal locations are rare. Cytologic diagnosis of YST on fine-needle aspiration (FNA) smears may be a challenge to the cytopathologist. Further neo-adjuvant therapy may be based on cytologic diagnosis making accuracy important. We studied FNA material from a hepatic mass in a pediatric patient to further define the(More)
Hepatic adenomatosis is a well-known complication of glycogen storage disease type Ia (von Gierke disease). Although most of these tumors have an appearance similar to sporadic hepatocellular adenomas, unusual histologic features have been reported, including Mallory hyaline, varying degrees of fibrosis, and aggregates of neutrophils. We report the fourth(More)
BACKGROUND Duct brushing cytology is an important tool in evaluation of the extrahepatic biliary tract and large pancreatic ducts. The emergence of neoadjuvant therapies underscores the importance of accurate preoperative diagnosis by noninvasive means. Liquid-based preparation methods, such as ThinPrep, have become popular for nongynecologic cytology(More)
BACKGROUND The utilization of lymphatic mapping techniques for breast carcinoma has made intraoperative evaluation of sentinel lymph nodes (SLN) attractive, because axillary lymph node dissection can be performed during the initial surgery if the SLN is positive. The optimal technique for rapid SLN assessment has not been determined. Both frozen sectioning(More)
Sentinel lymph node biopsy is an important new addition to the surgical management of patients with breast carcinoma. Sentinel nodes have a higher chance of containing metastases than do nonsentinel nodes. Sentinel lymph node biopsy provides an opportunity to stage breast carcinoma patients more accurately and to modify subsequent treatment. One of the most(More)
BACKGROUND The etiology of thrombotic thrombocytopenic purpura (TTP) remains undetermined. TTP has been associated with a number of secondary causes including infections, drugs, menses, pregnancy, autoimmune diseases, and bone marrow transplantation. Regardless of the inciting factors, it is widely accepted that endothelial injury and platelet aggregation(More)
