teratomas are rare germline tumors that originate from one or more embryonic germ cell layers. teratoma of the kidney is extremely rare, and less than 30 cases of primary intrarenal teratomas have been published to date. we report the main radiologic features of an unusual case of mature cystic teratoma arising from the left kidney in a two-year-old boy. a left-sided abdominal mass was detected...

Abstract Background Teratoma of the hepatoduodenal ligament is a rare entity. Only 17 cases teratoma exist in literature. Case presentation A girl with antenatally detected intraabdominal lesion was brought to us at age 3 years for prime concern progressive abdominal distension. Evaluation showed that mass arising likely from ligament. During excision, there an inadvertent pin-point perforation...

The lung and stomach are very unusual sites for teratoma. The histologic findings of intrapulmonary and gastric teratomas are not different from those arising in usual sites, such as the ovary or testis. However, preoperative diagnosis is sometimes difficult to make partly because of unusual location. We report here two cases of teratoma, one intrapulmonary teratoma and the other gastric. The i...

Mature cystic teratoma is one of the most common ovarian neoplasms, but extragonadal teratoma is rare. Teratoma in Douglas' pouch is extremely rare, and only 12 cases have been reported since the first case was described in 1978. We report a 20-year-old woman with a multicystic mass in Douglas' pouch that was treated via laparoscopic resection. The tumor consisted of cysts lined by stratified s...

Extragonadal teratomas are rare and account for only approximately 0.4% of all teratomas. The pathogenesis extragonadal is controversial poorly understood. We report a case an ovarian mature teratoma, which was discovered during autoamputation into omental teratoma.

Teratoma is a type of multipotential cell tumor, which includes a mixture of two or three germinal layers of ectodermis, endodermis, and mesodermis. Although neonatal sacrococcygeal teratoma has been frequently reported, its occurrence in older age is not common. In this study, we report a rare case of spinal intradural mature cystic teratoma in a 16-year-old male, emphasizing on considering th...

Mature teratoma comprises 5-10 % of all testicular neoplasms. Pure testicular teratoma is rare in adulthood with an incidence of 5 %. Regardless of differentiation postpubertal testicular teratoma have aggressive behavior and microscopic appearance of metastasis may differ from that of the primary. We present a case of pure teratoma of testis in an adult presenting as a metastatic germ cell tumor.

Sacrococcygeal teratoma (SCT) is rarely associated with syndromes. We report a female newborn with a prenatal diagnosis of small sacrococcygeal teratoma and postnatally diagnosed as having trisomy 13. The sacrococcygeal teratoma was excised. It was reported as mature teratoma. The child succumbed to sepsis postoperatively.
