URINE CYTOLOGY AND AXILLARY TESTING FOR INTERPRETATION AND FOLLOW-UP OF URINARY TUMORS.

Microscopic appearance of cells in urine cytological samples is the formal diagnostic approach adjunct to cystoscopy for the detection and follow-up of urinary tumors. However, cystoscopy is a surgical method and cytology may miss low-grade papillary tumors. Several assays and markers have been developed to assist in this.

Resveratrol and lycopene ameliorate contrast-induced nephropathy in a rabbit model.

Oxidative stress appears to possess a central role in CIN pathophysiology. Resveratrol (Res) and lycopene (Lyc) are strong natural antioxidants evaluated in a limited number of CIN animal studies in vivo. The aim of the study was to evaluate the potential renoprotective effects of Res/Lyc in a CIN rabbit model.

Cytological diagnosis of unifocal Langerhans cell histiocytosis in the temporomandibular joint.

Unifocal Langerhans cell histiocytosis (LCH) presents as a solitary focal bone lesion characterized by clonal proliferation of CD1a (+) and langerin(+) dendritic cells, derived from the bone marrow. In 38-69% of cases BRAF-V600E mutation is revealed. It gains attention to maxillofacial surgeons due to involvement of the orofacial region and early onset of jaws symptoms.

Intraoperative squash Cytology of diffuse glioma not otherwise specified, of the Cerebellum.

Objective: Diffuse glioma arises anywhere in the CNS, but most frequent in the cerebral hemispheres. The tumor tends to be seen in children and in younger adults aged 20-30. We report one such case in an older female patient presenting the intraoperative cytology of the tumor.

Osteoclast: like giant cell undiferrentiated pancreatic tumor diagnosed by means of EUS guided FNA.

Objective: Osteoclast-like giant cell tumours are rare abdominal malignant neoplasms mainly arising in the pancreas. Because of their rarity, clinical and cytopathology reports are very limited, and sonographic features have not been clearly specified ; these tumors are easily misdiagnosed by ultrasound as mucinous cystic tumors (MCTs)  or solid pseudopapillary neoplasms (SPNs).

Case Study: We report a case of osteoclast  like giant cell tumor arising in the pancreas of an 80 year old female patient offered by EUS-FNA cytology on direct and cell block slides.
