Youngest case of penile cancer?

What’s the youngest age at which penile cancer has ever been documented as occuring?

I can’t guarantee that this is the youngest case ever, but it must be close. The title of the case report really says it all.

For those interested in such things, a “rhabdomyosarcoma” is a malignant tumor of muscle tissue. In this case, the muscle in question was located in the penis.

Again, for those who are interested, the prefix “rhabdomyo” in medicine refers to skeletal muscle (as opposed to, say, the smooth muscle in blood vessels or in the bowel which is prefixed as “leiomyo”).

The suffix “sarcoma” refers to a cancer which has arisen in so-called ‘connective’ tissue, more properly termed ‘mesodermal tissue’. This means tissues such as bone (osteogenic sarcoma), cartilage (chondrosarcoma), muscle (rhabomyosarcoma or leiomyosarcoma), fat (liposarcoma), blood vessels (hemangiosarcoma), . . . Note how the common cancers affecting the lungs, breasts, prostate, bowels, etc are NOT in this list. Indeed, this latter group of those common cancers is covered by the term carcinoma (tumors arising from ‘epithelial’ cells/tissues).
