Spectrum of Renal Tumors Other Than Renal Cell Carcinoma with Emphasis on Cytomorphological, Immunohistochemical, and Cytogenetic Study.

Background: The role of fine needle aspiration cytology (FNAC) in the diagnosis of renal malignancies is established and has been getting more precise and important over a period of time. Knowledge of the pathology of uncommon renal neoplasms along with radiological and clinical correlations often aids in correct diagnosis.

Aims: The present study aims to describe the cytomorphological and immunohistochemical findings in the varied spectrum of renal tumors, other than renal cell carcinomas (RCC).

Doing More with Less: Fine Needle Aspiration Cytology in Pediatric Neoplasms.

Background: Cancer is one of the leading causes of death in the pediatric age group following infections. Among the diagnostic modalities, fine needle aspiration cytology (FNAC) is increasingly recognized as it permits rapid diagnosis with low cost and complication. In this study, we emphasize the diagnostic value of FNAC and describe the cytomorphological spectrum of tumors diagnosed on FNAC in pediatric patients with or without the aid of ancillary tests.

Diagnosis of solid tumors in infants by fine-needle aspiration cytology: 5 years retrospective study from a tertiary care oncology center in South India.

Introduction: Neuroblastoma (NB), Wilms tumor (WT), hepatoblastoma (HBL), germ cell tumors (GCT), rhabdomyosarcoma (RMS), and so forth are the commonly identified solid tumors in infants. Invasive diagnostic techniques are more challenging in infants than older children. fine needle aspiration cytology (FNAC) is a safe, minimally invasive and outpatient procedure which is time and cost-effective for solid tumor diagnosis.

Cytomorphological and immunohistochemical features of renal and extrarenal rhabdoid tumors.

Background: Rhabdoid tumors are rare, highly lethal neoplasms characterized by alterations of SMARCB1 gene in chromosome 22, which occurs in infants and children. Fine needle aspiration (FNA) is an effective technique to diagnose this tumor when combined with Immunohistochemistry (IHC) and molecular genetics. In this study, we describe four cases of renal and extra-renal rhabdoid tumor of which three cases were diagnosed on FNA with IHC.

A rare case of translocation (12;22) (p13;Q) in Ewing's sarcoma.

Cytogenetic or immunohistochemical studies are often required to differentiate Ewing's sarcoma (ES) from other small round cell tumors. Herein we report a case of 13-year-old boy who presented with a large presacral lesion. Hemogram and biochemical parameters were normal except lactate dehydrogenase showing value of 96.
