title: Cytodiagnosis of congenital mesoblastic nephroma: a case report.
abstract: Mesoblastic nephroma (MN) is the most common renal tumor diagnosed in infancy. A case of congenital MN was diagnosed in a 6-month old child by fine-needle aspiration cytology. The smears were cellular and consisted of plump spindle cells arranged in clusters along with scattered naked nuclei in the background. Blastemal, epithelial, or glomeruloid structures were not seen. Considering the age and the cytomorphology, a diagnosis of cellular variant of MN was offered which was confirmed on histopathology. Unlike Wilms tumor, preoperative chemotherapy is not required for MN. Hence cytologic diagnosis is important.
