A case of congenital mesoblastic nephroma of the left kidney was diagnosed in a 4-month-old child by fine needle aspiration cytology. The smears consisted of clustered and dyshesive spindle cells with minimal nuclear atypia and mitosis. No epithelial, tubular or glomeruloid differentiation was noted. Considering the age and cytomorphology, a diagnosis of mesoblastic nephroma was made. Histopathology of the nephrectomy specimen showed a tumor with features of atypical mesoblastic nephroma. Cytologic diagnosis of mesoblastic nephroma is important because the tumor has an excellent prognosis, and unlike Wilms' tumor, requires only surgery.
一名4个月大的儿童通过细针穿刺细胞学检查被诊断为左肾先天性中胚层肾瘤。涂片由聚集且分散的梭形细胞组成，核异型性和有丝分裂极少。未发现上皮、小管或肾小球样分化。考虑到年龄和细胞形态，诊断为中胚层肾瘤。肾切除标本的组织病理学显示肿瘤具有非典型中胚层肾瘤的特征。中胚层肾瘤的细胞学诊断很重要，因为该肿瘤预后良好，且与肾母细胞瘤不同，仅需手术治疗。
