One American went with friends on vacation in Hawaii to dive with aqualange and was taken to the hospital with a giant mole on his penis. The patient had serious breathing problems, vomiting, also heavily swollen face and lowered blood pressure.
The guy, recovering, said: "A friend was filming a diving on the camera, I decided to stick and pulled my penis into the shell, but the molluscum stuck him and did not let go. It was not painful and even pleasant. After a while I felt bad and only with the help of a partner was able to get out to the shore."
The allergy developed a little later, so the body responded to the digestive enzymes of the giant mole, which may have been trying to digest the penis.
Moral: Don’t go anywhere!
