    Molecular Diagnosis of Tubercular Lymphadenopathy from Fine-Needle Aspirates in Pediatric Patients.
    Acta Cytol 2017 20;61(3):173-178. Epub 2017 May 20.
    Department of Pathology, Jawaharlal Nehru Medical College Sawangi, Wardha, India.
    Objectives: The diagnosis of peripheral tubercular lymphadenopathy (TBLN) in pediatric patients is often a challenge because features evident on fine-needle aspiration cytology (FNAC) or tissue biopsy can be deceptive for the reason that they result from an immunological response. This study aimed to evaluate polymerase chain reaction (PCR) for Mycobacterium tuberculosis complex (MTBC) in pediatric patients under clinical suspicion for TBLN and to assess its role in the evaluation of cases cytodiagnosed as reactive lymphoid hyperplasia.

    Methods: This was a cross-sectional study conducted on 45 pediatric patients clinically suspected and unsuspected for TBLN. Read More

    Metastatic Pituitary Carcinoma to Cervical Lymph Node: Diagnosis by Fine Needle Aspiration and Review of the Literature.
    Acta Cytol 2017 12;61(3):242-246. Epub 2017 Apr 12.
    Department of Pathology and Laboratory Medicine, David Geffen School of Medicine, University of California at Los Angeles, Los Angeles, CA, USA.
    Background: Pituitary carcinomas are rare neoplasms whose designation requires demonstration of metastatic disease. No specific morphologic features can reliably distinguish pituitary carcinomas from pituitary adenomas, rendering the diagnosis particularly challenging. Furthermore, as reports of pituitary carcinoma on fine needle aspiration (FNA) biopsy are exceedingly rare in the literature, the cytological features of pituitary carcinoma are poorly characterized.

    Sperm Sediment Cytology: A New Technique for Diagnosing Occult Urologic Infections.
    Acta Cytol 2017 12;61(3):247-251. Epub 2017 Apr 12.
    Department of Laboratory Medicine, Russian Medical Academy of Postgraduate Education, Moscow, Russia.
    Background: Ill-defined chronic symptoms such as itching, burning, urethral discharge, and pelvic pain are not uncommon in male urologic patients. Often, microscopic urinalysis, bacterial cultures, and laboratory testing are non-contributory.
