Primary Immature Renal Teratoma in a Neonate

Ali Al Sharqi et al. Oman Med J. .

Abstract

Teratomas are neoplasms that commonly arise from the gonads. It is rare that they originate in the kidney. Immature intrarenal teratomas are exceptionally rare. To our knowledge, the current case will be the fifth immature intrarenal teratoma reported in the literature, in addition to being the first such case reported in a neonate.

Keywords: Neonate; Oman; Teratoma, Immature.
