Cytomorphology and immunohistochemistry of a recurrent clear cell odontogenic carcinoma with molecular analysis: A case report with review of literature.

Clear cell odontogenic carcinoma (CCOC) is a rare, odontogenic tumor of the jaws with mandibular involvement usually present in sixth decade of life with female preponderance. It is classified as a malignant tumor of odontogenic origin in 2005 by the World Health Organization because of its aggressive and destructive growth capacity and potential to metastasize. It needs to be distinguished from other primary and metastatic clear cell tumors of the oral and maxillofacial region.

Cytologic findings of acute leukemia in bronchoalveolar lavage fluid.

Bronchoalveolar lavage (BAL) is often performed in patients with acute leukemia developed with respiratory failure or pulmonary infiltrates. Patients usually undergo BAL to rule out infection. Occasionally, however, leukemic infiltrate may be detected.

Update on human polyomavirus BK nephropathy.

Polyomavirus BK (BKV) has ebeen identified as the main cause of polyomavirus-associated nephropathy, a major cause of renal allograft failure. Although BKV-associated nephropathy develops in only 2% to 5% of renal transplant recipients, its prognosis when present is very poor, with irreversible graft failure developing in 45% of affected patients. While the use of urine cytology for the detection of decoy cells has been in use for decades, other diagnostic modalities to detect BKV have emerged, including tissue biopsy, polymerase chain reaction, viral culture, and serology.

Malignant biphasic pleural mesothelioma metastatic to the liver diagnosed by fine-needle aspiration.

As malignant pleural mesotheliomas are most often rapidly fatal, distant metastases are rarely detected. Here, we report a unique case in which the diagnosis of metastatic pleural mesothelioma was made via cytologic examination of a fine-needle aspiration (FNA) of the liver. Recognition of the cytomorphologic features inherent to mesothelioma cells on FNA material may become important for proper patient management.

Ductal lavage in the high-risk patient.

Background: [corrected] This analysis was conducted in a single-surgeon clinical practice to evaluate the utility and practicality of performing ductal lavage in a population determined to be at high risk for breast cancer.

Methods: One hundred twenty patients with negative mammograms and/or negative breast examinations had nipple aspiration and ductal lavage performed by a single surgeon. All were at high risk either according to Gail risk score, a previous breast carcinoma, or nipple discharge.

Ductal lavage using medically aseptic technique in women at high risk for breast cancer.

Ductal lavage of the breast is a minimally invasive procedure used to collect epithelial cells from the lumen of the ductolobular system for cytologic analysis. The purpose of this study was to determine the safety of using an aseptic technique in performing ductal lavage. The study included 114 consecutive patients at high risk for breast cancer with clinically negative mammograms and no palpable masses.

Fine-needle aspiration of superficial and deeply seated lymph nodes on patients with and without a history of malignancy: review of 439 cases.

This study addresses the utility of fine-needle aspiration (FNA) in assessing lymphadenopathy in patients with and without a previous history of malignancy. We reviewed the FNAs of superficial and deeply seated lymph nodes performed at our institution over a period of 18 yr (1983-2001). Where applicable, we also reviewed and report here the results of subsequent surgical excisional biopsies.

Fine-needle aspiration of clinically suspicious palpable breast masses with histopathologic correlation.

Background: The purpose of this study was to compare the diagnostic accuracy of fine-needle aspiration (FNA) of clinically suspicious palpable breast masses in women younger and older than 40 years of age.

Methods: All women who had FNA biopsy with subsequent tissue biopsy were included. The cytologic diagnoses were classified into three groups: malignant, suspicious, or benign.

Diagnostic role of fine-needle aspiration of pancreatic allograft to detect rejection.

The purpose of this study was to assess whether the same principles to evaluate renal transplant by fine-needle aspiration (FNA) for rejection could be applied to pancreatic allograft. Between 1996-1998, 25 ultrasound-guided FNAs on 13 patients with pancreatic allograft were performed and ThinPrep made. The percentage of lymphocytes, lymphoblasts, monocytes, eosinophils, plasma cells, immunoblasts, and macrophages were calculated.

Application of adjunct techniques in cytologic material in the diagnosis of rhabdomyosarcoma: case report and review of the literature.

A 4(1/2)-yr-old female presented with right-sided pleural effusion and a retroperitoneal mass. Cytologic analysis of the pleural fluid yielded malignant small round blue cells, which were noncohesive, 3-4 times the size of lymphocytes. The malignant cells had hyperchromatic, pleomorphic nuclei with moderate amounts of vacuolated cytoplasm.

Diagnostic role of fine-needle aspiration of bone lesions in patients with a previous history of malignancy.

At the present time fine-needle aspiration (FNA) is considered a routine diagnostic procedure in evaluating neoplastic vs. nonneoplastic lesions in many organs, with high sensitivity and specificity. The purpose of this study was to assess the utility of FNA in areas of diagnostic difficulty and its limitations in evaluating bone lesions in patients with a previous history of malignancy.

Anaplastic T large cell lymphoma diagnosed by exfoliative cytology in a post renal transplant patient.

In the last two decades posttransplant lymphoproliferative disorders (PTLDs) have been recognized as a complication of organ transplantation with immunosuppression. The reported incidence of PTLDs in renal transplant patients ranges between 0.3-3% (Birkeland et al.

Brush cytology of the biliary tract: retrospective study of 278 cases with histopathologic correlation.

Bile aspiration during endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography has been used as a diagnostic tool in the evaluations of pancreatic and biliary tree strictures for the last two decades. However, recently biliary tract brush cytology has become the method of choice in evaluating pancreatic/biliary tract abnormalities. The aim of this study was to evaluate the accuracy of pancreatobiliary lesions by an endobiliary cytotechnique.
