What is extracranial germ cell tumor of childhood?

Rare family: This is a family of tumors that can be diagnosed by a pathologist (i suggest you get a consensus from 3 of us) that resemble to some degree the gametes and/or the cells of the unborn child. They run from totally benign to very malignant; thankfully today's treatment produces many good responses.

Collection of tumors: Germ cell tumors typically arise from testicles or ovaries. They can occur in the brain (but extracranial gcts do not). The exact tumor type is rarely of one variety in kids. Typically a mixed tumor is noted by pathologists. Usually, the mixed tumor types include some malignant components. Treatments are good. Chemo + surgery usually.
