Multicystic nephroma: a case report
BACKGROUND: Cystic nephroma is an uncommon pediatric renal neoplasm. It needsto be differentiated from cystic partially differentiated nephroblastoma and from other renalneoplasms showing extensive cystic change. It is scantily reported in the cytology literature. CASE:A 7-month-old female with a left-sided abdominal lump was diagnosed as having cystic Wilms’ tumoron computed tomography. Fine needle aspiration cytology showed cellular smears composed ofmonomorphic, round to oval cells, suggestive of a small round cell tumor, possibly rhabdomyosarcoma.However, histopathologic examination showed it to be a multicystic nephroma. On review of thecytologic smears, the blastemal component was absent. CONCLUSION: This case highlights 1 extreme andunexpected cytologic appearance of cystic nephroma; it may result in misdiagnosis.
