[A rare variant of testicular teratoma].

Tumors arising in human embryo from embryonic laying of an organ can be considered anomalies. Such tumors are renal adenomyosarcoma (Wilms' tumor), mesenchymoma and sarcoma botryoides of the prostatic gland, embryonal cancer of the testis, leydigocellular tumors of the testis and teratomas. Such anomaly as testicular teratoma occurs not rarely. However, testicular teratoma containing brain tissue is a rare finding. A case of teratoma of the left testis is reported in an 11-month-old infant. The tumor contained skin, appendages of the skin, cartilage, bone tissue, brain tissue, hair, fat.
