The Papanicolaou Society of Cytopathology has developed a set of guidelines for pancreatobiliary cytology including indications for endoscopic ultrasound guided fine-needle aspiration biopsy, techniques of the endoscopic retrograde cholangiopancreatography, terminology and nomenclature of pancreatobiliary disease, ancillary testing, and postbiopsy(More)
To determine cytologic features of epithelioid hemangioendothelioma (EHE) that would enable accurate diagnosis, we evaluated fine-needle aspiration biopsy (FNAB) smears from 11 histologically confirmed EHEs. The variably cellular smears comprised dispersed single cells and occasional cell aggregates. Dense stromal fragments were present in association with(More)
OBJECTIVE To compare the cytologic diagnoses and specimen adequacy of the ThinPrep Pap Test with historical data within a distinct patient population to assess test performance and its impact on clinical practice. STUDY DESIGN A total of 16,314 ThinPrep Pap tests were processed and evaluated at Fletcher Allen Health Care over a seven-month period. A(More)
INTRODUCTION Primary upper urinary tract (UT) urothelial carcinoma (UC) is rare. UT washing cytology is often used during UT surveillance. The Johns Hopkins Hospital template (JHHT) is primarily designed to use on lower tract urine cytology and the data on applying JHHT on UT cytology is limited. We herein study the value of UT cytology in detecting UTUC(More)
BACKGROUND The Papanicolaou Society of Cytopathology has developed a set of guidelines for respiratory cytology including indications for cytologic testing, techniques for cytologic sampling, terminology and nomenclature for respiratory diseases, ancillary testing, and recommendations for postcytologic diagnosis follow-up and management. METHODS All(More)
OBJECTIVES/HYPOTHESIS To evaluate the results of patients treated by transoral laser microsurgery and margin mapping with attention to deep margin dimensions in the lateral pharyngeal wall. STUDY DESIGN A microscopic margin analysis of multiblock surgical specimens applied to a prospectively accrued case series of squamous cell carcinoma of the palatine(More)
INTRODUCTION The increasing use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology to examine pancreatic neoplasms has led to an increase in the diagnosis of metastases to the pancreas. Renal cell carcinoma (RCC) is the most common metastasis to the pancreas. Our study examines 33 cases of metastatic RCC to the pancreas sampled by(More)
Coccidioidal pericarditis, an uncommonly diagnosed entity, may evolve to a constrictive process. Constrictive coccidioidal pericarditis requires pericardiectomy and antifungal therapy. In the elderly, pericardiectomy may be complicated by coagulopathy and septic shock. Despite potential toxicity, use of antifungal therapy early postoperatively offers the(More)
BACKGROUND The purpose of this study was to report the treatment outcomes of patients with advanced oropharyngeal cancer treated with transoral laser microsurgery (TLM) followed by radiation therapy (RT) at Mayo Clinic in Arizona. METHODS A retrospective study of 80 patients treated from January 1, 2000 to November 7, 2011 was performed. All patients had(More)
