Diagnostic dilemmas in fine needle aspiration cytology of an ectopic kidney: a case report.

Background: Congenital anomalies are easily diagnosed on radiology and rarely have an unusual presentation requiring an invasive diagnostic procedure. Fine needle aspiration cytology (FNAC), though a well-established diagnostic technique for abdominal and retroperitoneal lesions, is fraught with several challenges and pitfalls.

Case: We report a case of a 39-year-old woman with an ectopic kidney presenting as an abdominal mass.

Critical role of fine needle aspiration cytology and immunocytochemistry in preoperative diagnosis of pediatric renal tumors.

Objective: To evaluate accuracy and role of immunocytochemistry (ICC) in cytologic diagnosis of pediatric renal tumors.

Study Design: Fine needle aspirates from 75 cases of pediatric renal tumors were studied. Radiologic-guided aspirations were performed, with 6-7 smears stained with Papanicolaou and Giemsa stains.
