This week in the clinic: Keratocystic odontogenic tumor (old name = odontogenic keratocyst)

This week has a warning…

Be forewarned that there are some images that are not suitable for viewers of all ages (it gets a little bloody).

Ok, now that I’ve said that I’ll continue on with this amazing case of a keratocystic odontogenic tumor (which used be called an odontogenic keratocyst – name change due to tumor-like growth instead of cystic growth).  This case was present in the posterior maxilla and I have some clinical photos of the removal showing the actual lesion.  This location is not the most common location as keratocystic odontogenic tumors occur more frequently in the posterior mandible.  This entity contains keratin which has a yellow cheesy appearance and thsis yellowish color is evident on the clinical picture below.  Whenever considering a keratocystic odontogenic tumor on a radiograph, it should be noted that the following entities should also be included on a differential list.

1. Ameloblastoma

2. Odontogenic myxoma

3. Central hemangioma

Now onto the case.

Clinical photos – left image shows yellowish coloring of neoplasm – right image shows exposed roots after removal of the neoplasm.

Enjoy (and I hope the pictures weren’t too disturbing for you)!

This week in the clinic is a weekly series featuring cases I have come across since I started in the dental field.  These cases have been collected from throughout the United States and world.  While the series title is ‘This week in the clinic’, that does not necessarily mean the case was actually seen this week in the clinic.
