accumulation of fluid around the testis, due to fluid secreted into a potential space called the tunica vaginalis.

The TV is derived from extension of peritoneum wrapped around the testis

Q

Invasive SCC of penis

A

Most common cancer of the penis (95%) most cases occur in the uncircumcised males risk factors include poor hygiene, smoking, HPV infection (types 16 and 18) corpus spongiosum/cavernosum invasion important for staging

Q

teratoma

A

non-seminomatous tumor

mature form is composed of somatic-type tissues that can include intestine-type glands, respiratory epithelium, cartilage, muscle, squamous epithelium

immature form have a worse outcome. they contain immature neuroepithelium, blastema, carcinoid, or cellular stroma
