Metastatic teratoma from a regressed impalpable testicular primary.

چکیده
A young man presented with a perineal tumour which despite intensive investigation, remained of unknown origin and required radical excision. It was subsequently shown to be a metastasis from a primary regressed testicular teratoma. It is important to exclude a testicular origin in these patients wherever possible because such tumours are often chemosensitive.

Pure Testicular Teratoma Presenting as a Metastatic Germ Cell Tumor
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.

متن کاملRare Presentation of Metastatic Cystic Trophoblastic Tumor in a Patient Without Prior Chemotherapy
Cystic trophoblastic tumor (CTT) is a rare testicular germ cell tumor (GCT) predominantly seen in post-chemotherapy patients. It is prognostically similar to teratoma and requires no additional chemotherapy in the absence of a nonteratomatous GCT component. We report a case of metastatic CTT in a patient with primary testicular teratoma without prior chemotherapy. Retroperitoneal lymph node met...
متن کاملClonal origin of metastatic testicular teratomas.
PURPOSE Testicular teratomas in adult patients are histologically diverse tumors that frequently coexist with other germ cell tumor (GCT) components. These mixed GCTs often metastasize to retroperitoneal lymph nodes where multiple GCT elements are frequently present in the same metastatic lesion. Neither the genetic relationships among the different components in metastatic lesions nor the rela...
متن کاملNovel Case of Metastatic Testicular Immature Teratoma Invading the Duodenum
We present the first report of an immature teratoma arising from a germ cell testicular cancer invading the duodenum. While other seminomatous and non-seminomatous germ cell tumors are known to metastasize to the duodenum, this is the first such case involving an immature teratoma directly invading the duodenum from a metastatic retroperitoneal mass.
