# Which of the following tumors is most aggressive? (AIPG 91, AIIMS 2004)

A. Ameloblastoma
B. Odontogenic Myxoma
C. Odontoma
D. Fibrocarcinoma

Answer: B, Odontogenic Myxoma

ODONTOGENIC MYXOMA
- Aggressive, intraosseous neoplasms derived from embryonic odontogenic mesenchyme probably arise from the dental papilla or follicular mesenchyme.

- Nearly all lesions are found in the tooth bearing areas of maxillary and mandibular bone.

- Mandibular lesions are commonly found in the premolar-molar area.

- The lesions often produce multilocular radiolucency with a "soap bubble" or "honey comb" appearance in the bone.

- Thin and extremely delicate septa of bone are often seen to course through the radiolucent area and produce a "spider-web" like or "tennis racket" like appearance.
