This week, a Peruvian girl went to a doctor and complained that she felt a "sliding sensation" near the back of her nose. Upon closer examination, Dr. Renzo Arauco-Brown found the problem-- in her upper nostril, the doctor found a leech--with teeth (see above).
The girl apparently picked up the rare leech while swimming in lakes and rivers in the Amazon region. Known as tyrannobdella rex (meaning, "tyrant leech king) the pinkie-finger size leech has teeth that are five times larger than any other leech. The teeth may look small, but they hurt.
This is an odd thing... but it is not the first time it has happened. In medical history there are now three recorded cases. The other two people reported headaches.
