Primary renal mature cystic teratoma in an infant: A rare case presenting with an acute intestinal obstruction

Abstract

Primary renal teratomas are uncommon and preoperative diagnosis is difficult. Additional pathologies may be more difficult to diagnosis and may increase morbidity. We are reporting a case of large primary renal cystic teratoma which was presented with acute intestinal obstruction due to congenital band at ileum. Patient was successfully managed by dividing the congenital band and excision of teratoma in toto. Pathologic examination showed evidence for a primary renal mature teratoma. Serum alpha-fetoprotein is a reliable method of assessing recurrence.
