FNA Cytology in pediatric small cell glioblastoma.

Unlabelled: Small cell glioblastoma is a high anaplastic variant of GBM characterized by a monomorphic proliferation of small or medium cells with oval nuclei and scanty cytoplasm.

Case Study: The cytologic findings of a small cell glioblastoma in 11-year-old male and histologic features of the tumor using immunocytohistochemistry are reported.

Conclusion: The accurate preoperative diagnosis of a small cell glioblastoma is crucial to developing a curative surgical plan.

Cytology of Pericardial Effusion due to Malignancy.

Background: Malignant pericardial effusion occurs in one tenth of all cancers. It is a very serious disorder that is mainly a secondary process due to metastasis because primary neoplasms of the pericardium such as mesotheliomas, sarcomas being exceedingly rare [corrected]. Pericardial effusion specimens are uncommon and to the best of our knowledge the current study is the largest systematic evaluation of pericardial fluid cytology performed to date.

EUS - Fine- Needle Aspiration Biopsy (FNAB) in the Diagnosis of Pancreatic Adenocarcinoma: A Review.

Solid masses of the pancreas represent a variety of benign and malignant neoplasms of the exocrine and endocrine tissues of the pancreas. A tissue diagnosis is often required to direct therapy in the face of uncertain diagnosis or if the patient is not a surgical candidate either due to advanced disease or comorbidities. Endoscopic ultrasound (EUS) is a relatively new technology that employs endoscopy and high-frequency ultrasound (US).

Fine Needle Aspiration Biopsy (FNAB) in the Diagnosis of Hepatocellular Carcinoma: A Review.

Hepatocellular carcinoma (HCC) is the fifth more common cause of cancer and the third leading cause of cancer deaths worldwide. Despite advances in surgical and non surgical modalities in the treatment of HCC, a number of controversies regarding appropriate diagnostic procedures continue to evolve. A consensus statement from the European Association for the study of Liver Diseases (EASL) has been formulated to help clinicians standardize diagnostic approaches.

THE PROGNOSTIC SIGNIFICANCE OF P53, BCL2 AND MIB1 EXPRESSIONS RELATED WITH OTHER CLINICOPATHOLOGICAL VARIABLES IN SEROUS OVARIAN CARCINOMAS. A CLINICOPATHOLOGICAL STUDY IN PERITONEAL FLUIDS.

Objective: The first cytological study examining the expression of P53, BCL2 and MIB 1 expressions in correlation with other clinicopathological parameters in ascitic fluids of patients with serous ovarian carcinomas.

Materials And Methods: Fifty women 35-75 years old were diagnosed cytologically and confirmed histologically after operation in the University Hospital of Crete. All carcinomas were serous type and eight(8) of grade I, eighteen (18) of grade II and twenty two (22) of grade III.

Minos as a novel Tc1/mariner-type transposable element for functional genomic analysis in Aspergillus nidulans.

Transposons constitute powerful genetic tools for gene inactivation, exon or promoter trapping and genome analyses. The Minos element from Drosophila hydei, a Tc1/mariner-like transposon, has proved as a very efficient tool for heterologous transposition in several metazoa. In filamentous fungi, only a handful of fungal-specific transposable elements have been exploited as genetic tools, with the impala Tc1/mariner element from Fusarium oxysporum being the most successful.
