Two novel, bionanocomposite scaffolds were evaluated in a rodent model over the course of three months to determine whether these scaffolds possessed adequate biocompatibility characteristics to warrant further evaluation as possible tissue reconstruction scaffolds. These bionanocomposite scaffolds were comprised of amine-functionalized gold nanoparticles(More)
This is a case report of a previously undescribed 20q chromosomal deletion (del(20q)) in marginal zone lymphoma (MZL). A 54-year-old Caucasian male presented with an enlarging neck mass and multiple violaceous skin nodules over his chest. Biopsy of the neck mass and cervical lymph nodes revealed MZL. Cytogenetic evaluation of both lymph node and bone marrow(More)
Fifteen percent to 25% of appendices resected for a preoperative diagnosis of acute appendicitis have no neutrophilic infiltration, thus histologically "normal." The discrepancy between clinical presentation and the lack of definite morphologic changes is confounding. It has been indicated that mast cells may play a role in the pathogenesis of the(More)
OBJECTIVES The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) established diagnostic categories for cytologic specimens of the thyroid. Each category was associated with an estimated risk of malignancy. Recently, the non-invasive follicular variant of papillary thyroid carcinoma has been reclassified as benign. This reclassification may alter(More)
Frozen section is routinely used for intraoperative margin evaluation in carcinomas of the head and neck. We studied a series of frozen sections performed for margin status of head and neck tumors to determine diagnostic accuracy. All frozen sections for margin control of squamous carcinomas of the head and neck were studied from a 66 month period. Frozen(More)
BACKGROUND Endoscopic ultrasonographic-guided fine-needle aspiration (EUS-FNA) is the procedure of choice for the investigation of pancreatic lesions. It shows good sensitivity and excellent specificity. Diagnostic criteria have been published but not statistically validated for the diagnosis of malignancy and stratification of risk for malignancy.

Objectives To determine the impact of consensus conferences on the frequency of discrepant cases in a surgical pathology practice. Methods The percentage of discrepancies in cases reviewed at a weekly consensus conference was calculated for the first and last months of a 13-month period. Both interrater agreement and agreement with the consensus diagnoses(More)
BACKGROUND The Paris System for Reporting Urinary Cytology represents a significant improvement in classification of urinary specimens. The system acknowledges the difficulty in cytologically diagnosing low-grade urothelial carcinomas and has developed categories to deal with this issue. The system uses six categories: unsatisfactory, negative for(More)
BACKGROUND Papanicolaou Society of Cytopathology guidelines place low- and intermediate-grade pancreatic endocrine tumors into the "neoplastic, other" category whereas high-grade pancreatic endocrine tumors are placed in the "malignant" category. No attempt was made to stratify pancreatic endocrine tumors in the "neoplastic, other" category by likelihood(More)
