Retroperitoneal Teratoma in Infancy; Report of an Unusual Entity

Sarangi PK, Hui P, Mangaraj PD, Kumar S

Primary retroperitoneal teratoma in infancy is extremely rare. In children, it accounts for 3.5-4% of all germ cell tumours and 1-11% of primary retroperitoneal neoplasms. Clinical presentation is often asymptomatic or may present as a palpable mass or abdominal distension. The imaging findings of teratoma are characteristic. Early diagnosis is important for prompt surgical resection. We present a case of huge retroperitoneal teratoma in a 5-month-old child presenting with abdominal swelling where computed tomography findings are distinctive. Biopsy led to the definitive diagnosis of mature cystic teratoma of retroperitoneum.
