Question 126 · LDEK · Benign tumors
According to the presently binding histological classification of the odontogenic tumors by WHO, complex odontoma ranks among:
1) odontogenic benign tumors;
2) benign lesions connected to the bone;
3) odontogenic tumors containing the odontogenic epithelium with a mature fibrous tissue without ectomesenchyme;
4) odontogenic tumors containing odontogenic epithelium and odontogenic ectomesenchyme, which can create hard tissue structures;
5) odontogenic tumors containing mesenchyme and/or odontogenic ectomesenchyme, which can contain odontogenic epithelium.
The correct answer is:
2) benign lesions connected to the bone;
3) odontogenic tumors containing the odontogenic epithelium with a mature fibrous tissue without ectomesenchyme;
4) odontogenic tumors containing odontogenic epithelium and odontogenic ectomesenchyme, which can create hard tissue structures;
5) odontogenic tumors containing mesenchyme and/or odontogenic ectomesenchyme, which can contain odontogenic epithelium.
The correct answer is:
- A. 1,4.
- B. 1,5.
- C. 2,3.
- D. 2,4.
- E. 2,5.
